The provided text is a 510(k) summary for a medical device (Excelsior XT-27 Microcatheters) and details its acceptance criteria and the study performed to demonstrate substantial equivalence, but it does not describe an AI/ML device. Therefore, the questions related to AI/ML specific criteria (such as sample sizes for test and training sets, number of experts for ground truth, adjudication methods, multi-reader multi-case studies, standalone performance, and data provenance) are not applicable to this document.
However, I can provide the acceptance criteria and study information that is available for this mechanical microcatheter from the document.
1. Table of acceptance criteria and the reported device performance:
| Test | Acceptance Criteria (Inferred from "Pass") | Reported Device Performance |
|---|---|---|
| Guide Catheter Compatibility with 1.17 mm (0.046") ID | Maximum forces required to completely deliver and retrieve the microcatheter inside a 0.046" ID guide catheter with worst-case sized ancillary devices must be acceptable/pass. | Pass |
| Tensile Strength for Joints and Marker Band | Tensile strength after preconditioning by simulated use with worst-case sized ancillary and interventional devices must be acceptable/pass. | Pass |
| Particulate and Coating Integrity | Hydrophilic coating integrity and particulate generation under simulated use conditions with a 0.046" ID guide catheter, and comparison to cleared comparator devices, must be acceptable/pass. | Pass |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Sample Size for Test Set: The document does not specify the exact number of samples (e.g., number of microcatheters tested) used for each bench test. It mentions testing with "ancillary devices that represent worst-case sizes" for the Guide Catheter Compatibility test and "worst-case sized ancillary devices and interventional devices" for the Tensile Strength test.
- Data Provenance: The study is described as "Bench testing," indicating it was conducted in a laboratory setting. There is no information regarding country of origin or whether it was retrospective or prospective, as these terms are typically applied to clinical studies involving human or animal subjects.
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 this is a mechanical device performance study, not an AI/ML diagnostic or prognostic study requiring expert opinion for ground truth. The "ground truth" here is the physical performance of the device against engineering specifications.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- Not applicable for the same reason as point 3. Bench testing results are typically adjudicated by meeting predefined engineering specifications and criteria, not by expert consensus in the same way as diagnostic reads.
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, a multi-reader multi-case (MRMC) comparative effectiveness study was not performed. This type of study is relevant for AI-assisted diagnostic devices, which is not what this device is.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. This is a physical medical device (microcatheter), not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" in this context is based on engineering specifications and performance criteria for the physical device. For example, for tensile strength, the ground truth would be a defined minimum force the joints and marker band must withstand without failure. For compatibility, it would be the ability to successfully deliver and retrieve the microcatheter within the specified guide catheter with acceptable force.
8. The sample size for the training set:
- Not applicable. This is not an AI/ML device, so there is no training set.
9. How the ground truth for the training set was established:
- Not applicable for the same reason as point 8.

One radiopaque tip marker is positioned at the distal tip of the device to facilitate fluoroscopic visualization. The Excelsior XT-27 Microcatheter is coated on the outer surface with Hydrolene™ coating which reduces friction during manipulation in the vessel.
The Excelsior XT-27 Microcatheters are available in effective lengths of both 135cm (53.1 inch) and 150 cm (59.1 inch), with two distal shaft configurations achieved through distal shaft lengths of 6 cm (XT-27 model) and 18 cm (XT-27 Flex model). Both straight tip and Pre-Shaped versions are available.
This document describes the Stryker Neurovascular Excelsior® XT-27™ Microcatheter and its 510(k) submission for market clearance. The submission relies on demonstrating substantial equivalence to predicate devices through a series of bench tests.
Here's an analysis of the provided information regarding acceptance criteria and the study that proves the device meets them:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria for the Excelsior XT-27 Microcatheter are largely based on demonstrating equivalence to the predicate devices (K000177, Renegade™ Hi-Flo™ Microcatheter and K042568, Excelsior® SL-10 Pre-Shaped Microcatheter). The "Result" column explicitly states "Met same criteria as predicate," indicating that the performance of the Excelsior XT-27 Microcatheter was found to be comparable to or better than the predicate devices for these specific tests.
| Test / Performance Metric | Acceptance Criteria (Implicitly based on Predicate) | Reported Device Performance |
|---|---|---|
| Visual Inspection | ||
| Durable Hydrophilic Coating | Performance comparable to predicate device | Met same criteria as predicate |
| Surface Defects | Performance comparable to predicate device | Met same criteria as predicate |
| Surface-Extraneous matter | Performance comparable to predicate device | Met same criteria as predicate |
| Dimensional Measurement | ||
| Kink Radius of Curvature / Proximal Shaft Kink | Performance comparable to predicate device | Met same criteria as predicate |

| Hemocompatibility (Direct Contact; Complement Activation C3a and SC5b-9; PTT; blood cell counts and hemoglobin / hematocrit levels) | Non-hemolytic | Non-hemolytic |
| Materials Mediated Pyrogen levels, Rabbit test | Non-pyrogenic | Non-pyrogenic |
| USP impurities, <661> | No significant impurities / Comparable to predicate | None |
| Latex test, ELISA Inhibition | No latex present / Comparable to predicate | None |
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample sizes used for each of the bench tests. It also does not provide information about data provenance in terms of country of origin or whether the tests were retrospective or prospective. Given the nature of bench testing for a medical device, it is typically prospective, with samples of the device being manufactured and then tested in controlled laboratory environments.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of those Experts
This information is not provided in the document. For bench testing, "ground truth" is typically established through adherence to test methodologies and specifications, often informed by engineering standards and regulatory guidance, rather than expert consensus on individual cases.
4. Adjudication Method for the Test Set
This information is not provided. As mentioned above, bench testing relies on objective measurements and predefined acceptance criteria rather than expert adjudication in the way clinical studies might.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs without AI Assistance
This information is not applicable and not provided. The Excelsior XT-27 Microcatheter is a physical medical device (microcatheter), not an AI-powered diagnostic or assistive tool. Therefore, an MRMC comparative effectiveness study comparing human readers with and without AI assistance would not be relevant to its evaluation.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
This information is not applicable and not provided. As it is a physical medical device, there is no "algorithm only" performance to be evaluated in a standalone manner.
7. The Type of Ground Truth Used
The ground truth for most of these tests is established by:
- Engineering Specifications and Design Requirements: For dimensional measurements, kink radius, advancement/retraction force.
- Established Biomedical Test Standards: For biocompatibility tests (cytotoxicity, irritation, systemic toxicity, sensitization, hemocompatibility, pyrogenicity, USP impurities, latex). These standards define the methods and acceptance criteria for classifying a material as non-toxic, non-irritating, etc.
- Comparison to Predicate Device Performance: For many performance characteristics (e.g., visual inspection, simulated use), the "ground truth" for the new device is that its performance must be equivalent or superior to the already legally marketed predicate devices.
8. The Sample Size for the Training Set
This information is not applicable and not provided. As a physical medical device, there is no "training set" in the context of machine learning or AI. The design and manufacturing processes are refined through engineering iterations, but this is distinct from an algorithmic training process.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable and not provided for the same reasons as point 8.
In Summary:
The document focuses on demonstrating substantial equivalence of the Excelsior® XT-27™ Microcatheter to its predicate devices through comprehensive bench testing. The acceptance criteria for most tests are implicitly or explicitly that the new device must perform comparably to (or better than) the predicate devices, or meet established safety and performance standards (especially for biocompatibility). The study design is largely a series of controlled laboratory tests performed on samples of the device. Aspects related to AI, human readers, or large-scale data training sets are not relevant to this type of device submission and therefore not included.

Here's an analysis of the provided text in relation to your request:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly state "acceptance criteria" in the typical quantitative sense (e.g., a specific percentage accuracy or precision). Instead, the acceptance criteria are implicitly that the modified devices (with pre-shaped tips) retain the same performance characteristics and safety profile as the predicate devices. The study performed is a "testing in support of substantial equivalence determination."
| Characteristic/Test | Acceptance Criteria (Implicit) | Reported Device Performance |
|---|---|---|
| Functionality | Equivalent to predicate devices | "Same as predicate device" for all listed characteristics (materials, design, dimensions, markers, coating, effective length, GDC compatibility) |
| Materials | Equivalent to predicate devices | "Same as predicate device" |
| Method of Operation | Equivalent to predicate devices | Stated as "substantially equivalent" |
| Intended Use | Equivalent to predicate devices | Stated as "substantially equivalent" |
| Indications for Use | Equivalent to predicate devices | Stated as "substantially equivalent" |
| Biological Safety | Equivalent to predicate devices | "Biological safety testing support the claim of substantial equivalence," stated as "substantially equivalent." |
| Tip configuration | Ability to offer pre-shaped tips with secondary shaping option | "Offered with Pre-Shaped Tips with the option of secondary shaping... As compared to the predicate which was cleared with straight tip, steam shapeable by physician prior to use." |
| In-vitro testing results (various) | Performance equivalent to predicate devices / safety thresholds | "The results of in-vitro testing (tip shape retention, appearance of the tip, tip dimensions, static rupture, tensile I ho reading of the worling test, and coil, guide catheter compatibility) ... support the claim of substantial equivalence." |
2. Sample Size and Data Provenance
- Test Set Sample Size: Not specified. The document refers to "in-vitro testing" but does not detail the number of units tested for each characteristic.
- Data Provenance: The data appears to be prospective as it involves "in-vitro testing" conducted specifically for this 510(k) submission. No information is given about the country of origin of the data beyond "Boston Scientific" which is a US-based company, suggesting the testing was likely conducted in the US or by a US-affiliated entity.
3. Number of Experts and Qualifications for Ground Truth
Not applicable. This submission is for a medical device (microcatheter) and relies on engineering and biocompatibility testing, not on expert interpretations of medical images or clinical data to establish a "ground truth" in the diagnostic sense.
4. Adjudication Method for the Test Set
Not applicable. As noted above, this isn't a study involving human interpretation of data where adjudication would be necessary.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. This type of study is typically performed for diagnostic devices where the performance of human readers, with and without AI assistance, is evaluated. This submission is for a microcatheter, which is an interventional device, not a diagnostic one.

This document is a 510(k) clearance letter for a blood glucose test strip, which falls under IVD (In Vitro Diagnostic) devices. For IVD devices, the acceptance criteria and study details are typically presented differently than for AI/ML-based diagnostic software. Instead of metrics like sensitivity, specificity, AUC, or reader studies, IVD device performance is usually evaluated based on accuracy against a reference method (e.g., laboratory analyzer), precision (repeatability, reproducibility), and interference studies.
Based on the provided text, there is no detailed information on acceptance criteria and a study report in the format typically requested for AI/ML devices. The document is primarily an FDA clearance letter and an "Indications For Use" statement. It confirms that the device is "substantially equivalent" to a legally marketed predicate device.
Therefore, many of the requested points for describing acceptance criteria and a study cannot be directly extracted from this document because it is not a study report.
However, I can infer some information based on the context of 510(k) submissions for IVD devices and the provided text:
1. A table of acceptance criteria and the reported device performance:
This information isn't explicitly in the provided text. For blood glucose meters and strips, typical acceptance criteria would involve accuracy metrics (e.g., certain percentage of results falling within specific ranges compared to a lab reference, or mean absolute relative difference - MARD), precision (coefficients of variation), and linearity. The "substantially equivalent" determination implies that the device met performance standards comparable to the predicate device.
2. Sample size used for the test set and the data provenance:
Not provided in this document. Studies for blood glucose meters typically involve a diverse set of patient samples with varying glucose levels.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
For blood glucose meters, the "ground truth" is typically established by measurements from a central laboratory's reference analyzer, not by expert interpretation.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable for this type of IVD device where ground truth is machine-determined (reference lab).
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:
Not applicable. This is not an AI/ML device, and there are no "human readers" interpreting results in the way an AI would assist a radiologist.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
The device (test strips) essentially operates in a "standalone" manner in that the chemical reaction on the strip and the meter's reading algorithm directly provide a result. There isn't an AI "human-in-the-loop" component in the traditional sense for this type of device.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):
For blood glucose test strips, the ground truth is established by a laboratory reference method, typically a clinical chemistry analyzer with high accuracy and precision, such as a YSI glucose analyzer.
8. The sample size for the training set:
Not applicable in the context of AI/ML training. For IVD devices, development involves analytical studies (e.g., accuracy, precision, interference) and clinical studies. The "training set" concept doesn't directly apply in the same way.
9. How the ground truth for the training set was established:
Not applicable as there isn't a "training set" in the AI/ML sense. Ground truth for performance evaluation samples would be established via a laboratory reference method.
Summary based on the document:
The provided document is a 510(k) clearance letter for a medical device (blood glucose test strips). It attests to the device's "substantial equivalence" to a legally marketed predicate device. This implies that the device demonstrated comparable performance to the predicate through studies (not detailed in this letter), likely including accuracy against a reference method, precision, and interference studies. However, the specific acceptance criteria, study methodologies, and performance results are not included in the provided text.

The Excelsior SL-10 Microcatheter is intended to assist in the delivery of diagnostic agents, such as contrast media, and therapeutic agents, such as occlusion coils, into the peripheral, coronary and neurovasculature.
The Excelsior SL-10 Microcatheter is a single lumen device designed to aid the physician in accessing distal vasculature when used with a guide catheter and guidewire. The device shaft is comprised of graded materials of varying durometers, from a flexible tip to a semirigid proximal end. Stainless steel wire reinforcement provides for strength during torque transmission while the inner liner provides for lubricity. The hub / strain reliefs provide for kink resistance from the proximal end. A luer fitting on the catheter hub is used for the attachment of accessories. The radiopaque tip with one or two markers allows for visualization under fluoroscopy. The outer surface is coated with a hydrophilic coating which reduces friction during navigation in the vasculature. A steam shaping mandrel accessory is packaged with the catheter.
This submission describes the Excelsior™ SL-10 Microcatheter. The manufacturer is seeking substantial equivalence to existing predicate devices based on in vitro performance testing.
Here's an analysis of the acceptance criteria and study information provided:
1. Table of Acceptance Criteria and Reported Device Performance
The submission does not explicitly provide a table of acceptance criteria with specific thresholds. Instead, it states that "All testing indicates that the device is safe and performs according to its intended use." This is common for predicate device comparisons where the performance is expected to be at least equivalent to the predicate, rather than meeting a specific numerical benchmark.
However, based on the testing mentioned, we can infer the performance aspects evaluated:
| Performance Aspect | Reported Device Performance |
|---|---|
| Dimensional Inspection | Performed, implied to meet specifications |
| Tensile Strength | Performed, implied to meet safety and function |
| Burst Pressure | Performed, implied to meet safety and function |
| Flow Rate | Performed, implied to meet efficacy requirements |
| Withdrawal Force Testing | Performed, implied to meet safety and function |
| Biocompatibility | Confirmed according to ISO-10993 |
2. Sample Size Used for the Test Set and the Data Provenance
The document does not specify the sample sizes used for the in vitro performance tests. The data provenance is not explicitly stated as retrospective or prospective, nor are countries of origin mentioned. However, since these are in vitro performance tests, they are typically conducted in a laboratory setting by the manufacturer.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable. The ground truth for this device is established through objective in vitro measurements and comparison to predicate devices, rather than expert consensus on diagnostic interpretations.
4. Adjudication Method for the Test Set
Not applicable. As noted above, the "ground truth" is based on objective measurements and established standards (like ISO-10993) and comparison to predicate devices, not subjective expert reviews requiring adjudication.
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
Not applicable. This is a medical device (microcatheter), not an AI diagnostic tool. Therefore, an MRMC study comparing human readers with and without AI assistance is irrelevant.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. This is a physical medical device, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the performance claims is based on:
- Objective Measurements: Results of the in vitro performance tests (dimensional, tensile, burst, flow rate, withdrawal force).
- Established Standards: Biocompatibility verified according to ISO-10993.
- Predicate Device Equivalence: The primary "ground truth" for regulatory clearance is substantial equivalence to the legally marketed predicate devices (Tracker-10 Microcatheter and Excelsior 1018 Microcatheter) in terms of functionality, intended use, design, materials, and method of operation.
8. The Sample Size for the Training Set
Not applicable. This device is not an AI algorithm; therefore, there is no "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set.

The Excelsior 1018 Microcatheter is intended to assist in the delivery of diagnostic agents, such as contrast media, and therapeutic agents, such as occlusion coils, into the peripheral, coronary, and neurovasculature.
The Excelsior 1018 Microcatheter is a single lumen device designed to aid the physician in accessing the distal vasculature when used with a guiding catheter and steerable guidewire. Graded shaft stiffness ranging from a highly flexible tip to a semi-rigid proximal section aids the physician in tracking over selectively placed guidewires without displacement of the wire. A luer fitting located on the catheter hub is used for the attachment of accessories. A radiopaque tip facilitates fluoroscopic visualization. The outer diameter is coated with a hydrophilic surface that reduces friction during manipulation in the vessel. The catheter is packaged with a steam shaping mandrel accessory.
The provided text describes a 510(k) submission for the Excelsior™ 1018 Microcatheter, focusing on its substantial equivalence to a predicate device, the TurboTracker-18 Infusion Catheter. The submission primarily details performance testing and biocompatibility to support this claim, rather than a clinical study with traditional acceptance criteria for a new AI/software device.
Therefore, many of the requested categories for AI/ML device studies (such as MRMC studies, ground truth establishment for training sets, number of experts for ground truth, sample sizes for test/training sets, data provenance, and adjudication methods) are not applicable to this 510(k) summary, as it pertains to a physical medical device.
1. A table of acceptance criteria and the reported device performance
Since this is a submission for a physical microcatheter, the "acceptance criteria" are related to established engineering and biocompatibility standards rather than clinical performance metrics typical of an AI device. The document states that "performance testing (tensile strength, coefficient of friction, static rupture, tip buckling, dimensional inspection, critical bend radius, particulate analysis, and coil compatibility) and biocompatibility testing support this claim of substantial equivalence."
While specific numerical acceptance criteria and reported performance values for each of these tests are not provided in the given text, the submission states that the results "demonstrate that the Excelsior 1018 Microcatheter is substantially equivalent to the predicate TurboTracker-18 Infusion Catheter device." This implies that the Excelsior 1018 Microcatheter met the necessary performance and safety standards to be considered equivalent to the predicate device.
| Test Type | Acceptance Criteria (Implied) | Reported Device Performance (Implied) |
|---|---|---|
| Tensile Strength | Met established engineering standards for medical catheters and was comparable to predicate. | Met. |
| Coefficient of Friction | Met established engineering standards for medical catheters and was comparable to predicate. | Met. |
| Static Rupture | Met established engineering standards for medical catheters and was comparable to predicate. | Met. |
| Tip Buckling | Met established engineering standards for medical catheters and was comparable to predicate. | Met. |
| Dimensional Inspection | Conformed to specified dimensions and was comparable to predicate. | Met. |
| Critical Bend Radius | Met established engineering standards for medical catheters and was comparable to predicate. | Met. |
| Particulate Analysis | Met established safety standards for particulate matter in medical devices. | Met. |
| Coil Compatibility | Compatible with target coils (GDC-10 & GDC-18). | Met. |
| Biocompatibility | Met ISO 10993 standards for biological evaluation of medical devices. | Met. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
Not applicable to this type of device submission. Performance testing usually involves a defined number of units per test, but these are engineering tests, not clinical studies with "test sets" in the AI/ML sense. Data provenance would be from internal lab testing at Boston Scientific.
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. Ground truth in this context refers to established engineering specifications and biocompatibility standards, not expert assessments of clinical data for AI performance.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods are used in clinical studies, particularly for AI, to resolve discrepancies in ground truth labeling. This submission relies on objective engineering measurements and standard biocompatibility assessments.
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
Not applicable. This is not an AI-assisted device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the performance testing is based on established engineering specifications, industry standards (e.g., for biocompatibility), and comparison to the predicate device's characteristics. For coil compatibility, the "ground truth" is whether the microcatheter can successfully deliver the specified GDC coils.
8. The sample size for the training set
Not applicable. This is not an AI/ML device that requires a training set.
9. How the ground truth for the training set was established
Not applicable.
