The TightRail Guardian Motorized Dilator Sheath is intended for use in patients requiring the percutaneous dilation of tissue to facilitate removal of cardiac leads.
The TightRail Guardian Motorized Dilator Sheath is a sterile, single use, prescription only device used for cardiac leads. The device is comprised of:
- Drive Assembly
- Dilation Extension Selection (DES) Assembly
- Motor Drive Handle
- Outer Sheath Accessory
- Fish Tape Accessory
The motorized dilator sheath is advanced or retracted along the target lead to be removed. Pulling the trigger on the handle of the TightRail Guardian device results in activation of the motor and subsequent rotation of the inner shaft and cam blade. Triager activation results in bidirectional rotation mechanism. Actuation of the distal dilation mechanism causes dilation of tissue and fibrous attachments surrounding the lead tarqeted for removal, thereby facilitating removal of said lead. The device has two modes of operation, providing dilation with the blades shielded or extended. The diameter sizes range from 9 French (F) to 13 F. The nominal effective length of the TightRail Guardian is 47.5 cm. The outer sheath accessory may be used for additional support by creating a conduit for the device's shaft assembly. The outer sheath may also be used to maintain venous access for guidewire placement, prior to implantation of a new lead. The fish tape accessory may be used to feed a target lead and locking stylet through the inner lumen of the device.
The provided text describes the regulatory clearance for the TightRail Guardian Motorized Dilator Sheath and does not contain information about a study proving the device meets acceptance criteria in the context of an AI/ML powered device evaluation.
The document is a 510(k) summary for a medical device (a motorized dilator sheath), outlining its intended use, design, and comparison to predicate devices for regulatory clearance. It focuses on demonstrating substantial equivalence to existing devices, not on evaluating the performance of an AI/ML model.
Therefore, I cannot provide the requested information regarding:
- A table of acceptance criteria and reported device performance (as it relates to AI/ML metrics).
- Sample size and data provenance for an AI/ML test set.
- Number of experts and qualifications for establishing ground truth in an AI/ML context.
- Adjudication method for an AI/ML test set.
- MRMC comparative effectiveness study results for AI vs. without AI assistance.
- Standalone algorithm-only performance.
- Type of ground truth used for an AI/ML model.
- Sample size for the training set of an AI/ML model.
- How ground truth for the training set was established for an AI/ML model.
The document lists various Design Verification and Validation Testing performed, such as Simulated Use Testing, Human Factors Evaluation, and Biocompatibility testing. These are typical engineering and safety tests for a physical medical device, not performance metrics for an AI/ML algorithm.
The statement "Preclinical and clinical data was not required to demonstrate substantial equivalence" further indicates that this is a traditional medical device clearance, not one involving extensive clinical trials or AI/ML performance evaluation studies against specific acceptance criteria for diagnostic/prognostic accuracy.

The device is intended for the ablation of tissue in the removal of IVC filters that have failed a previous retrieval method.
The CavaClear Laser Sheath is a 14Fr or 16 Fr laser sheath that transmits ultraviolet energy in (b)(4) pulse durations from Spectranetics' Excimer Laser generators to the tissue at the distal tip of the device. When the laser activates, a small amount of the tissue is ablated through photochemical, photothermal, and photomechanical interaction, vaporizing tissue overgrowth in order to allow for inferior vena cava (IVC) filter removal. The CavaClear Laser Sheath operates at repetition rates of 25-80Hz and fluence of 30-60mJ/mm2.
The provided text describes the CavaClear Laser Sheath, a laser-powered device used for the retrieval of IVC filters that have failed previous removal methods. While the document details various aspects of the device's testing and clinical performance, it does not pertain to an AI/ML powered medical device. Therefore, information typically associated with AI/ML device acceptance criteria, such as training and test set data, ground truth establishment by experts, adjudication methods, and MRMC studies, is not present in this document.
The acceptance criteria and the study proving the device meets these criteria are based on traditional medical device evaluation metrics, focusing on safety and effectiveness in a real-world clinical setting.
Here's an analysis of the provided information, framed as closely as possible to your request, but acknowledging the lack of AI-specific details:
Acceptance Criteria and Device Performance for CavaClear Laser Sheath
The acceptance criteria for the CavaClear Laser Sheath are defined by two primary performance goals: a safety endpoint and an efficacy endpoint. These goals were based on meta-analysis of existing literature for IVC filter retrieval procedures.
Table of Acceptance Criteria and Reported Device Performance
| Performance Metric | Acceptance Criterion | Single-Center Experience Performance | Multi-Center Experience Performance |
|---|---|---|---|
| Primary Safety Endpoint: Device-Related Major Complication Rate | < 10% (Upper Confidence Limit) | 2.9% (95% CL: 0.8%, 7.2%) | 4.0% (95% CL: 1.3%, 9.0%) |
| Primary Efficacy Endpoint: Procedural Technical Success Rate | > 89.4% (Lower Confidence Limit) | 95.7% (95% CL: 90.8%, 98.4%) | 95.2% (95% CL: 89.9%, 98.2%) |
Study Proving Device Meets Acceptance Criteria:
The study conducted was a retrospective analysis of real-world evidence from multiple medical centers.
-
Sample Size Used for the Test Set and Data Provenance:
- Total Subjects: 265
- Single-Center Experience (Test Set 1): 139 subjects
- Multi-Center Experience (Test Set 2): 126 subjects from 6 sites
- Data Provenance: United States (US), retrospective. Data was collected from medical records between March 2012 and February 2021.
-
Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts:
- The document states that "All site reported complications were independently adjudicated to assess relatedness to use of the laser and to evaluate the appropriate severity classification based on the current SIR guidelines."
- Number of Experts: Not explicitly stated, but implies at least one independent adjudicator.
- Qualifications of Experts: Not explicitly stated, but "adjudicated... based on the current SIR guidelines" implies experts familiar with interventional radiology and complication grading (e.g., interventional radiologists, vascular surgeons).
-
Adjudication Method for the Test Set:
- "All site reported complications were independently adjudicated."
- The specific method (e.g., 2+1, 3+1) is not detailed, but it was an independent review process based on SIR (Society of Interventional Radiology) grading guidelines for complications.
-
If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done:
- No. This study evaluated the performance of a physical medical device (laser sheath) in performing a medical procedure, not an AI/ML algorithm requiring human reader performance evaluation.
-
If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable, as this is not an AI/ML algorithm. The device's performance is inherently linked to human operation by trained medical professionals within a clinical setting.
-
The Type of Ground Truth Used:
- The ground truth for safety (complications) and efficacy (technical success) was established through clinical judgment and independent adjudication of real-world patient outcomes, based on medical records and SIR grading guidelines. Technical success was defined based on practitioners' clinical judgment and reported as such.
-
The Sample Size for the Training Set:
- Not applicable in the context of AI/ML training. The "training" for this device refers to human medical professional training on its use, not algorithmic training data.
-
How the Ground Truth for the Training Set Was Established:
- Not applicable as there is no algorithmic training set. The "ground truth" for human training would be established through established medical protocols, clinical best practices, and expert consensus on effective and safe procedural techniques. The document mentions a required training program for users.

- A table of acceptance criteria and reported device performance.
- Sample sizes for test sets or data provenance.
- Number or qualifications of experts for ground truth.
- Adjudication methods.
- MRMC comparative effectiveness studies or effect sizes.
- Standalone algorithm performance.

Turbo-Power is indicated for laser atherectomy of de novo or restenotic lesions in native infrainguinal arteries and for the treatment of femoropopliteal artery in-stent restenosis (ISR) in bare nitinol stents, with adjunctive Percutaneous Transluminal Angioplasty (PTA).
The Turbo-Power (2.0mm, 2.3mm) Laser Atherectomy Catheter are laser atherectomy devices designed for use with the CVX-300™ Excimer Laser System. The Turbo-Power (2.0mm) and (2.3mm) Laser Atherectomy Catheters are sterile, single use, prescription only devices used for peripheral atherectomy. The Turbo-Power (2.0mm) and (2.3mm) are used to ablate lesions with reference vessel diameters of ≥3.0mm. Turbo-Power (2.0mm) and (2.3mm) Laser Atherectomy Catheters are comprised of 2 subassemblies: 1. Catheter Subassembly 2. Motor Drive Unit (MDU) Subassembly The working length of the Turbo Power Laser Atherectomy Catheter is constructed of multiple optical fibers arranged eccentrically around a 0.018" (0.46 mm) guidewirecompatible lumen. The PTFE guidewire lumen tip is attached to a stainless steel torque wire which is connected to the MDU at the proximal end of the working length. The multifiber laser catheter transmits ultraviolet energy from the Spectranetics CVX-300 Excimer Laser System through the tip of the laser to an obstruction in the patient's artery. The outer surface of the laser catheter working length is hydrophilic-coated, and the distal tip of the catheter contains a radiopaque marker band for in situ visibility. The ultraviolet energy transmitted from the CVX-300 laser system is used to photoablate multiple morphology lesions which may be comprised of atheroma, fibrosis, calcium, and thrombus, thus recanalizing diseased vessels. Photoablation is the process by which energy photons cause molecular bond disruption at the cellular level without thermal damage to surrounding tissue.
The provided text describes a 510(k) premarket notification for Spectranetics, Inc.'s Turbo-Power (2.0mm, 2.3mm) Laser Atherectomy Catheters, seeking substantial equivalence to a predicate device (K172687).
This document does not contain information related to an AI/ML powered medical device and therefore does not have the answers to questions 1-9. The device described is a physical medical device (laser atherectomy catheter) with minor design modifications (improved battery clip and battery pull tab), not an AI/ML algorithm.
Therefore, I cannot fulfill the request to describe the acceptance criteria and study proving an AI/ML device meets the acceptance criteria based on the provided text. The traditional medical device testing mentioned (Motor Drive Unit Lifetime Test, Motor Drive Unit Functionality Test, Pull Tab Isolation Test) are specific to the physical catheter's mechanical performance, not the performance of an AI/ML model.

The provided text is a 510(k) summary for the Spectranetics Turbo-Power Laser Atherectomy Catheters. The document states that "New clinical data was not required to demonstrate substantial equivalence," and much of the testing was "leveraged from the predicate Turbo-Power (2.3mm)" and summarized within this submission (which is not fully provided). Therefore, many of the requested details about acceptance criteria, specific performance metrics, sample sizes, and ground truth establishment for a new study are not available in the provided text because a new extensive clinical study for this specific 510(k) was not conducted.
However, based on the information provided, here's what can be inferred or directly stated:
1. A table of acceptance criteria and the reported device performance
The document lists types of performance data collected but does not provide specific acceptance criteria or quantitative performance results in a table format.
| Acceptance Criteria Category | Reported Device Performance |
|---|---|
| Design Verification and Validation Testing | Met all acceptance criteria as required by the risk analysis. |
| Simulated Use Testing | Performed. Outcomes not detailed. |
| Functional Testing | Performed. Outcomes not detailed. |
| Physical Testing | Performed. Outcomes not detailed. |
| Laser Testing | Performed. Outcomes not detailed. |
| Sterilization | Product adoption equivalency per AAMI TIR:28-2009. |
| Pre-clinical GLP Studies | Compared usability and procedural safety to predicate devices. Supported premarket notification. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Test Set Sample Size: Not specified for any new testing. Much of the data was leveraged from predicate devices. For pre-clinical GLP studies, the sample size is not disclosed.
- Data Provenance: Not specified for any new testing. The phrase "pre-clinical GLP studies" suggests controlled laboratory or animal studies, not human clinical trials.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
Not applicable, as new clinical data requiring expert-established ground truth was not explicitly detailed or required. The testing involved "Design Verification and Validation Testing" and "Pre-clinical GLP studies," which typically don't involve expert ground truth in the same way clinical imaging studies do.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable, as new clinical data requiring adjudication was not explicitly mentioned or required.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No MRMC study was mentioned. This device is a physical medical device (laser atherectomy catheter), not an AI-powered diagnostic tool. Therefore, the concept of "human readers improve with AI vs without AI assistance" does not apply.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This question is not applicable to a physical medical device like a laser atherectomy catheter. The device itself performs the intended function, often with human operation.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the pre-clinical GLP studies, the ground truth would likely be based on direct observations, measurements of tissue effects, and safety endpoints within the experimental setup, rather than expert consensus on diagnostic images or pathology. The document does not provide details.
8. The sample size for the training set
Not applicable. This device is not an AI algorithm that requires a "training set."
9. How the ground truth for the training set was established
Not applicable, as there is no "training set" for this physical device.

The Turbo-Elite devices are indicated for use in the treatment, including atherectomy, of infrainguinal stenoses and occlusions.
The 0.014" and 0.018" Over-the-Wire (OTW) Turbo-Elite laser catheters are also indicated for use as an accessory to the use of the Turbo-Tandem System in the treatment of femoropopliteal artery in-stent restenosis (ISR) in bare nitinol stents, when used in conjunction with Percutaneous Transluminal Angioplasty (PTA).
Spectranetics Turbo-Elite Laser Ablation Catheters are percutaneous intravascular devices constructed of multiple optical fibers arranged around a guidewire lumen for Over-the-Wire (OTW) configurations, and bundled together for Rapid-Exchange (Rx) versions. Turbo Elite Laser Ablation Catheters are available in an Over the Wire (OTW) configuration and a Rapid Exchange (RX) configuration. The Turbo-Elite laser catheters in the OTW configuration are available in six different catheter tip sizes (0.9mm, 1.4mm, 1.7mm, 2.0mm, 2.3mm, and 2.5mm) and three different guide-wire compatibilities (0.014″, 0.018″, and 0.035"). New indication clearance is only being requested for the OTW configurations of Turbo-Elite catheters compatible with 0.014" and 0.018" guidewires.
The multifiber laser catheters transmit ultraviolet energy from the Spectranetics CVX-300® Excimer Laser System to an obstruction in the patient's artery. The ultraviolet energy is delivered to the laser catheter to photoablate fibrous, calcific, and atheromatous lesions, thus recanalizing diseased vessels. Photoablation is the process by which energy photons cause molecular bond disruption at the cellular level without thermal damage to surrounding tissue.
The provided text is a 510(k) summary for a medical device (Spectranetics Turbo-Elite Laser Atherectomy Catheters). It focuses on establishing substantial equivalence to a predicate device and expanding indications for use. While it mentions a clinical study (ABLATE), it does not provide acceptance criteria in the form of a table with specific device performance numbers, nor does it detail all the specific information requested in the prompt regarding the study's methodology for acceptance testing as if it were an AI/ML device.
However, I can extract the information that is present and indicate where information is missing based on the prompt's requirements.
Missing Information Acknowledgment:
The document does not include details typically found in studies proving an AI/ML device meets acceptance criteria, such as:
- A table of specific numerical acceptance criteria (e.g., minimum sensitivity, specificity, or accuracy thresholds for an AI/ML diagnostic device).
- Information on test set sample size for AI validation.
- Data provenance for AI training/test sets.
- Number/qualifications of experts for AI ground truth.
- Adjudication methods for AI ground truth.
- MRMC comparative effectiveness study results (AI vs. without AI).
- Standalone performance for an algorithm.
- Ground truth type for AI (e.g., pathology, outcomes data).
- Training set sample size for AI.
- How ground truth for the training set was established for AI.
This is because the device described, the "Spectranetics Turbo-Elite Laser Atherectomy Catheters," is a physical medical device (a laser catheter) and not an AI/ML software device. The clinical study mentioned (ABLATE) is designed to demonstrate the safety and effectiveness of the physical device for its intended use in treating infrainguinal stenosis and occlusions, not to validate an AI/ML algorithm's performance against specific metrics.
Based on the provided text, here is the available information related to the clinical study and device performance, rephrased to fit the prompt's structure where possible, and explicitly noting missing AI/ML-specific details:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria here refer to the primary safety and effectiveness endpoints of the ABLATE clinical study for the physical device, not an AI/ML algorithm.
| Acceptance Criteria Category (for physical device) | Acceptance Criteria (Target/Goal) | Reported Device Performance (from ABLATE study) |
|---|---|---|
| Primary Safety Endpoint | Percent freedom from Major Adverse Events (MAE) through day 30 follow-up. | Met (Specific percentage not provided, but stated as "hypotheses were met.") |
| Primary Effectiveness Endpoint | Mean reduction in percent stenosis at the time of the procedure by Angiographic Core Lab assessment. | Met (Specific percentage reduction not provided, but stated as "hypotheses were met." An average reduction of 42% was achieved for residual stenosis). |
| Additional Effectiveness Analysis 1 | Lesions had ≤50% residual stenosis post Turbo-Elite treatment. | Successful (Average reduction of 42% in stenosis was noted). |
| Additional Effectiveness Analysis 2 | Long-term freedom from Target Lesion Revascularizations (TLR) through 180-days. | Successful (Specific percentage not provided, but stated as "successful.") |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Sample Size (Test Set): Not explicitly stated numbers of patients in the ABLATE clinical study.
- Data Provenance:
- Country of Origin: Not specified in the provided text.
- Retrospective or Prospective: The ABLATE study is referred to as a "clinical study," which typically implies a prospective design for gathering safety and effectiveness data for device approval.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Number of Experts: Not specified.
- Qualifications of Experts: The "Angiographic Core Lab" is mentioned for assessing reduction in percent stenosis, implying expert (likely interventional cardiologists or radiologists specializing in vascular imaging) review, but no specific qualifications or numbers are provided.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not specified.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. This is a physical device, not an AI/ML system. Therefore, an MRMC study comparing human reader performance with and without AI assistance is not applicable and was not conducted. The study evaluated the direct impact of the laser atherectomy catheter.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- No. This is a physical device, not an AI/ML algorithm. Standalone algorithm performance is not applicable.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
For the physical device, the "ground truth" for effectiveness and safety endpoints included:
- Clinical Outcomes Data: Major Adverse Events (MAE) and Target Lesion Revascularizations (TLR) are clinical outcomes.
- Angiographic Assessment: "Mean reduction in percent stenosis at the time of the procedure by Angiographic Core Lab assessment" serves as a measure of the device's immediate effectiveness against a measurable anatomical change.
8. The sample size for the training set
- Not applicable. This is a physical device undergoing a clinical trial for safety and effectiveness, not an AI/ML algorithm that requires a training set.
9. How the ground truth for the training set was established
- Not applicable. This is a physical device approval, not an AI/ML algorithm.

The Turbo-Power (2.0mm) Laser Atherectomy Catheter is a laser atherectomy device designed for use with the CVX-300™ Excimer Laser System. The Turbo-Power (2.0mm) Laser Atherectomy Catheter is a sterile, single use, prescription only device used for peripheral atherectomy.
The Turbo-Power (2.0mm) is used to ablate lesions with reference vessel diameters of ≥3.0mm. Turbo-Power (2.0mm) Laser Atherectomy Catheter is comprised of 2 subassemblies:
-
- Catheter Subassembly
-
- Motor Drive Unit (MDU) Subassembly
The working length of the Turbo Power Laser Atherectomy Catheter is constructed of multiple optical fibers arranged eccentrically around a 0.018" (0.46 mm) guidewirecompatible lumen. The PTFE quidewire lumen tip is attached to a stainless steel torque wire which is connected to the MDU at the proximal end of the working length.

The provided document is a 510(k) summary for the Spectranetics Turbo-Power (2.0mm) Laser Atherectomy Catheter. It describes the device, its intended use, and substantial equivalence to a predicate device. However, it does not contain specific acceptance criteria or detailed results of a study proving the device meets those criteria, nor does it include information about sample sizes for test sets, data provenance, expert ground truth, adjudication methods, MRMC studies, standalone performance, or training set details.
The document mentions that various tests were conducted to validate and verify that the subject device met all acceptance criteria, as required by the risk analysis. These tests included:
- Design Verification and Validation Testing: Simulated Use Testing, Functional Testing, Physical Testing, Laser Testing.
- Sterilization: Product adoption equivalency per AAMI TIR:28-2009.
- Biocompatibility: Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Direct Hemolysis, Indirect Hemolysis, In Vivo Thrombogenicity-Ovine Model, Genotoxicity - Ames Test, Material Mediated Pyrogenicity.
- Pre-clinical Data: A pre-clinical GLP study was conducted to compare usability and procedural safety of the Turbo-Power (2.0mm) and Turbo-Power (2.3) laser catheters.
The document does not provide the specific acceptance criteria for these tests or the reported performance values against those criteria in a table format. It only states that the device "met all acceptance criteria." It also explicitly states that new clinical data was not required to demonstrate substantial equivalence, which means there isn't a human-in-the-loop or standalone study with clinical outcomes described here.
Therefore, many of the requested details cannot be extracted from this document.
Here's a breakdown of what can and cannot be answered based on the provided text:
1. A table of acceptance criteria and the reported device performance
- Cannot be provided. The document states that testing was performed and the device "met all acceptance criteria," but it does not specify what those criteria were or the actual performance results in a quantifiable manner.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Cannot be provided. The document mentions "Simulated Use Testing," "Functional Testing," "Physical Testing," "Laser Testing," and a "pre-clinical GLP study." However, it does not specify sample sizes for any of these tests or the data provenance (e.g., retrospective/prospective, country of origin). The pre-clinical study involved an "Ovine Model," indicating animal data.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not applicable/Cannot be provided. This question typically applies to studies involving human interpretation or clinical endpoints. The document describes engineering, biocompatibility, and animal (ovine model) studies. It does not mention any studies where human experts established ground truth for a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not applicable/Cannot be provided. Similar to point 3, this is relevant for studies involving human assessment or interpretation, which are not detailed here.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. The document explicitly states "New clinical data was not required to demonstrate substantial equivalence." An MRMC study would fall under clinical data. This device is a physical catheter, not an AI system.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable. This device is a physical catheter, not an algorithm or AI system. Its performance is evaluated through engineering, biocompatibility, and pre-clinical animal studies, not standalone algorithmic performance.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Cannot be fully specified. For the engineering tests, ground truth would likely refer to engineering specifications and performance benchmarks. For the biocompatibility tests, it would be established standards (e.g., ISO standards for cytotoxicity, sensitization). For the pre-clinical GLP study using an ovine model, ground truth would have been based on observations and measurements from the animal subjects related to usability and procedural safety as defined by the study protocol.
8. The sample size for the training set
- Not applicable. The document describes a medical device (catheter), not an AI system that requires a "training set."
9. How the ground truth for the training set was established
- Not applicable. Same as point 8.

The TightRail Sub-C Rotating Dilator Sheath is intended for use in patients requiring the percutaneous dilation of tissue to facilitate removal of cardiac leads, indwelling catheters, and foreign objects.
The TightRail Sub-C Rotating Dilator Sheaths are mechanical, intra-operative devices. The devices consist of a proximal handle drive mechanism with a distal dilation catheter. The sheaths are packaged with an optional outer support sheath. The dilator sheath is advanced, withdrawn, and rotated about the lead, catheter or foreign object to be removed. Actuating the trigger on the proximal handle activates a rotary dilation mechanism sheathed at the distal terminus of the catheter. Rotation of the inner shaft is translated to axial actuation of the dilation mechanism via a cam path contained within the distal components. Actuation of the distal dilation mechanism causes dilation of tissue and fibrous attachments surrounding the object targeted for removal, thereby facilitating removal of said object. The diameter sizes range from 9 French (F) to 13 F. The nominal effective length of the TightRail Sub-C is 15.5 cm.
The provided text describes a medical device, the "TightRail Sub-C Rotating Dilator Sheath," and its premarket notification (510(k)) to the FDA. The document focuses on demonstrating substantial equivalence to predicate devices rather than providing a detailed study that defines and meets specific acceptance criteria for a new, standalone device performance claim. Therefore, much of the requested information regarding algorithm performance, sample sizes for test/training sets, expert adjudication, MRMC studies, and ground truth establishment is not available in this document because it pertains to the evaluation of a software algorithm or AI, which is not the subject of this medical device submission.
Here's a breakdown of the available information:

2. Sample Size Used for the Test Set and the Data Provenance
The document does not explicitly state the numerical sample sizes for each specific test (e.g., how many balloons were tested for burst volume, how many animals were used in the preclinical study). However, it lists various "Design Verification and Validation Testing" categories, along with "Performance Testing," "Sterilization," and "Biocompatibility" tests.
- Preclinical Testing: Mentioned as "preclinical GLP testing." The specific number of animals is not provided.
- Data Provenance: The preclinical study was a prospective study conducted to demonstrate the device's intended use in SVC occlusion. The location of these studies is not specified, but they were conducted by the device manufacturer for regulatory submission in the USA.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
This information is not applicable in the context of this device and study. The studies described are engineering, materials, and animal studies, not studies involving human interpretation or subjective assessment by experts to establish a "ground truth" as it would be for AI/imaging devices. The "ground truth" for these tests are the objective measurement results and observations of physical performance and biological response.
4. Adjudication Method for the Test Set
Not applicable. As described above, the tests are primarily objective measurements and observations, not requiring expert adjudication in the manner medical imaging studies might.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not done. The device is a physical medical device (balloon catheter), not an AI algorithm for diagnostic interpretation that would involve human readers.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This device is a physical medical device, not an algorithm.
7. The Type of Ground Truth Used
For the various tests:
- Engineering and Performance Tests: Ground truth is based on the design specifications and measurable physical/chemical properties (e.g., dimensions, material properties, inflation/deflation times, bond strengths, leak detection).
- Biocompatibility Tests: Ground truth is established by standardized biological assays and observation of biological reactions (e.g., cell viability for cytotoxicity, skin reaction for sensitization, blood component analysis for hemolysis).
- Preclinical Animal Study: The ground truth for this segment relates to the objective demonstration of SVC occlusion within the animal model, observed through physiological measurements or imaging.
8. The Sample Size for the Training Set
Not applicable. This device is not an AI/ML algorithm that requires a training set. The term "training set" is not relevant to the described studies for this physical medical device.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this device.

Turbo-Power™ Laser Atherectomy Catheted for laser atherectomy of de novo or restenotic lesions in native infrainguinal arteries and for the treatment of femoropopliteal artery in-stent restenosis (ISR) in bare nitinol stents, with adjunctive Percutaneous Transluminal Angioplasty (PTA).
The Turbo-Power System (Laser Atherectomy Catheter) is a laser atherectomy device designed for use with the CVX-300™ Excimer Laser System. The Turbo-Power Laser Atherectomy Catheter is a sterile, single use, prescription only device used for peripheral atherectomy.
Turbo-Power is used to directionally ablate infrainguinal concentric and eccentric lesions in vessels that are 3.5mm or greater in diameter. Turbo-Power Laser Atherectomy Catheter is comprised of 2 subassemblies:
-
- Catheter Subassembly
-
- Motor Drive Unit (MDU) Subassembly
The working length of the Turbo Power Laser Atherectomy Catheter is constructed of multiple optical fibers arranged eccentrically around a 0.018" (0.46 mm) quidewirecompatible lumen. The PTFE guidewire lumen tip is attached to a stainless steel torque wire which is connected to the MDU at the proximal end of the working length. The multifiber laser catheter transmits ultraviolet energy from the Spectranetics CVX-300 Excimer Laser System through the tip of the laser to an obstruction in the patient's artery. The outer surface of the laser catheter working length is hydrophilic-coated, and the distal tip of the catheter contains a radiopaque marker band for in situ visibility. The ultraviolet energy transmitted from the CVX-300 laser system is used to photoablate multiple morphology lesions which mav be comprised of atheroma, fibrosis, calcium, and thrombus, thus recanalizing diseased vessels. Photoablation is the process by which energy photons cause molecular bond disruption at the cellular level without thermal damage to surrounding tissue.
This document, a 510(k) summary for the Spectranetics Turbo-Power Laser Atherectomy Catheter (K152181), does not contain information about the device's acceptance criteria or a study directly proving the device meets specific acceptance criteria in the format requested.
Instead, it focuses on demonstrating substantial equivalence to predicate devices (Turbo-Tandem and Turbo-Elite) based on various performance data and existing clinical studies of the predicate devices.
Here's an breakdown of the information that is available and a note on what is missing based on your request:
Missing Information:
- A table of acceptance criteria and the reported device performance: This document does not provide a table specifying predefined quantifiable acceptance criteria (e.g., specific thresholds for success, failure rates, accuracy) for the Turbo-Power device itself, nor does it present its performance against such criteria. The "Performance Data" section lists types of tests conducted but not the results or the criteria for those results.
- Sample size used for the test set and the data provenance: While a "pre-clinical GLP study" is mentioned, details about its sample size, specific test set, and data provenance are not provided. The clinical data leveraged are from studies of the predicate devices.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable, as no direct acceptance criteria study with expert ground truth is described for the Turbo-Power device.
- Adjudication method for the test set: Not applicable for the same reason as above.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, if so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a laser atherectomy catheter, not an AI diagnostic tool.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable, as this is not an AI algorithm.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): For the predicate device studies (EXCITE, PATENT, CELLO), outcomes data (MAE, TLR, restenosis reduction, acute procedural success) were used as endpoints, which can be considered a form of ground truth for assessing clinical effectiveness. However, no ground truth is explicitly described for the Turbo-Power device's direct performance against acceptance criteria.
- The sample size for the training set: Not applicable, as this is not an AI device.
- How the ground truth for the training set was established: Not applicable.
Information that is available (or can be inferred) from the document, relevant to the spirit of your request, but focused on substantial equivalence rather than direct acceptance criteria fulfillment:
The document states that the following testing was conducted to validate and verify that the subject device met all specifications:
- Simulated Use Testing
- Functional Testing
- Physical Testing
- Laser Testing
- Software Testing
- Sterility/Biocompatibility/Physiochemical Testing
Pre-clinical Data:
- Study Type: A pre-clinical GLP study was conducted to compare the usability and procedural safety of the Turbo-Power and Turbo-Tandem laser catheters.
- Purpose: To support the premarket notification and demonstrate similarity to the predicate device.
- Sample Size/Data Provenance: Not specified in this document.
- Ground Truth: Usability and procedural safety endpoints, likely determined by direct observation and measurement in the GLP study, but the specific metrics are not detailed.
Clinical Data (Leveraged from Predicate Devices to Support Indications for Use):
The document explicitly states: "New clinical data was not required to demonstrate substantial equivalence." Instead, the following clinical studies of the predicate devices were leveraged:
-
The EXCITE Trial:
- Device: Spectranetics Turbo Elite Laser Ablation Catheter and Spectranetics Turbo-Tandem Laser Guide Catheter with Laser Atherectomy Catheter.

- Study Design: Prospective randomized controlled trial (2:1 randomization).
- Endpoints/Ground Truth:
- Primary Safety: Freedom from Major Adverse Event (MAE) through 30 days (all-cause death, major amputation in target limb, Target Lesion Revascularization (TLR)).
- Primary Efficacy: Freedom from TLR through 6 months.
- Results: Both primary safety and efficacy hypotheses were met. No statistical difference in major amputation rates, mortality, serious adverse events, or adverse events between groups.
- Sample Size/Provenance: Not specified in this document, but implied to be a multi-center trial.
-
The PATENT Study:
- Device: Spectranetics peripheral atherectomy laser catheters (Turbo Elite) used with Turbo-Booster catheters.
- Focus: Safety and performance for in-stent restenosis of nitinol stents in femoropopliteal arteries.
- Study Design: Multicenter prospective registry.
- Endpoints/Ground Truth: Safety and performance (specific metrics not detailed in this summary).
- Sample Size/Provenance: Involved 5 EU centers (specific sample size not detailed).
-
The CELLO (CLiRpath Excimer Laser System to Enlarge Lumen Openings) Study:
- Device: Turbo-Elite used with Turbo-Booster catheters.
- Focus: Safety and performance for treatment of Peripheral Artery Disease (PAD).
- Endpoints/Ground Truth:
- Primary Effectiveness: ≥ 20 percent reduction in percent diameter stenosis (assessed by angiographic core lab).
- Secondary Effectiveness: Acute procedural success (visual assessment of final residual stenosis).
- Primary Safety: Occurrence of major adverse events (clinical perforation, major dissection requiring surgery, major amputation, CVA, MI, death) at procedure time and through six months.
- Results: Demonstrated safety for the treatment of patients with stenoses and occlusions crossable by a guidewire in SFA and popliteal artery, with no occurrence of major adverse events through six-month follow-up.
- Sample Size/Provenance: Not specified in this document.
Conclusion for Substantial Equivalence:
The document concludes that the Turbo-Power System is substantially equivalent to the Turbo-Tandem and Turbo-Elite based on:
- Similarities in design.
- Performance data (referring to the listed testing).
- Pre-clinical data (GLP study).
- Leveraged clinical data from the predicate devices.
The implication is that the Turbo-Power device, having successfully completed its internal specifications and pre-clinical testing, is expected to perform similarly to the predicate devices whose clinical safety and effectiveness have already been established by the EXCITE, PATENT, and CELLO trials against their respective clinical endpoints.
