Re: K243795
Trade/Device Name: pREBOA-PRO Catheter
Regulation Number: 21 CFR 870.4450
Catheter, Intravascular Occluding, Temporary
Review Panel: Cardiovascular (CV)
Regulation: 870.4450
The pREBOA-PRO Catheter is intended for temporary partial or complete occlusion of large vessels and blood pressure monitoring including patients requiring emergency control of hemorrhage.
The pREBOA-PRO™ Catheter is a large vessel occlusion catheter with a dedicated lumen for pressure monitoring. The device consists of a semi-compliant balloon, in-line pressure relief valve (safety valve), atraumatic distal tip (P-tip™), dual lumen catheter shaft and a hub with extension lines to provide access to each lumen.
The pREBOA-PRO™ Catheter is designed with flow channels to enable precise, smooth control of inflation and deflation of the balloon. Instructions for how to titrate the balloon for partial occlusion, if so desired by the clinician, are included in the Instructions for Use.
The device has an effective length of 72 cm and is compatible with 7 Fr introducer sheaths as shown in the compatibility section of the IFU. The catheter has a unibody design and is intended to be placed and advanced without a guidewire. In addition, the catheter is compatible with guidewires up to 0.025" that may be used to facilitate subsequent vascular procedures after a REBOA procedure. An orange peel-away sheath is preloaded on the catheter shaft covering the balloon to ease insertion of the catheter's P-tip™ into an introducer sheath hemostasis valve. A catheter shaft provides appropriate stiffness with a distal tip (P-tip™) designed for atraumatic advancement of the catheter in a blood vessel. Pad printed marks on both sides of the outer catheter shaft indicate distance to the center of the balloon as well as average insertion depth ranges to the center of aortic Zones 1 and 3 to facilitate proper placement. Radiopaque platinum iridium marker bands are located at the functional ends of the balloon to facilitate and visualize accurate balloon placement when used with imaging. The proximal end of the catheter has a hub and extension lines. The arterial line lumen is used to monitor blood pressure above the balloon. Below the balloon core aortic pressure monitoring is possible through the side arm of the sheath. The balloon lumen is used to inflate and deflate the balloon as needed. An in-line safety valve is connected to the balloon lumen stopcock and is designed to help prevent over-inflation of the balloon. The stopcocks provide control to each of the catheter's two lumens. The orange peel-away sheath can be separated from the catheter shaft after insertion if needed. The device is a single-use, sterile device.

The Bridge Plus Occlusion Balloon catheter is is indicated for temporary vessel occlusion of the Superior Vena Cava (SVC) and Inferior Vena Cava (SVC) in applications including perioperative occlusion and emergency control of hemorrhage.
The Bridge Plus Occlusion Balloon is designed to be delivered percutaneously to the superior vena cava (SVC) or the inferior vena cava (IVC) for the purpose of providing occlusion, emergency control of hemorrhage and perioperative occlusion in the event of an SVC or IVC tear or perforation during a vascular procedure.
The Bridge Plus Occlusion Balloon catheter is constructed of a compliant polyurethane balloon mounted on a 12Fr dual lumen nylon shaft. This guidewire lumen is used to pass the catheter over a guidewire. The balloon has a length of 80mm and inflation diameter ranging from 20-29mm. Three platinum-iridium radiopaque markers are placed within the balloon segment of the catheter to provide visual reference points for balloon positioning within the SVC or IVC prior to inflation.
This FDA 510(k) clearance letter pertains to a medical device, the Bridge Plus Occlusion Balloon, and therefore the "acceptance criteria" and "study that proves the device meets the acceptance criteria" refer to the performance specifications and verification/validation testing described in the submission, rather than clinical study endpoints for AI/software devices. The provided document does not describe a study involving human readers or AI algorithms.
Here's a breakdown of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document lists various Design Verification and Validation Testing categories. For these types of medical devices, the "acceptance criteria" would be the pre-defined performance specifications for each test, which the device must meet to be considered safe and effective and substantially equivalent to a predicate device. The "reported device performance" indicates that the Bridge Plus Occlusion Balloon met these specifications.
Note: The document does not provide the specific quantitative acceptance criteria or detailed numerical performance results for each test. Instead, it states that "Performance testing data have demonstrated that the Bridge Plus Occlusion Balloon meets performance specifications to support substantial equivalence to the predicate devices." and that the conducted tests "validate and verify that the subject device met all specifications."
| Acceptance Criteria Category | Reported Device Performance |
|---|---|
| Design Verification & Validation Testing | Met specifications for substantial equivalence. |
| Dimensional and Visual Tests | Met specified dimensions and visual appearance requirements (e.g., Crossing Profile, Balloon Compliance, Balloon Working Length, Catheter Effective Length, Surface Appearance, Distal Tip Configuration, Luer Compatibility, Guidewire Compatibility). |
| Performance Testing | Met specified performance requirements (e.g., Deployment and Retraction, Withdrawal Force, Inflation and Deflation Time, Inflated Balloon Size Stability, Balloon Bond Strength, Tip Bond Strength, Hub Bond Strength, Flexibility and Kink, Torque Strength, Vessel Occlusion, Leak Testing, Balloon Fragmentation & Burst Volume, Device Fatigue). |
| Sterilization | Demonstrated compliance with ISO 11135:2014 Amd 1, confirming the appropriateness of existing process challenge devices and validating bioburden methods. |
| Biocompatibility | Met biocompatibility requirements for various tests (Cytotoxicity, Sensitization, Irritation or Intracutaneous Reactivity, Material Mediated Pyrogenicity, Acute Systemic Toxicity, Direct and Extract Hemolysis, Partial Thromboplastin Time, Platelet & Leukocyte Count, Comparative Surface Analysis, Complement Activation). |
2. Sample Size Used for the Test Set and Data Provenance
The document describes laboratory and bench testing rather than clinical studies with "test sets" of patient data. Therefore, the concept of sample size for a test set of data and data provenance (country of origin, retrospective/prospective) is not applicable in the context of this device's submission. The testing was conducted on the physical device itself.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Since this is a physical medical device (occlusion balloon) and not an AI/software device, the concept of "ground truth established by experts" for a test set is not applicable. Device performance was evaluated against engineering specifications and industry standards.
4. Adjudication Method for the Test Set
As this is not an AI/software device or a clinical study with subjective assessments, an "adjudication method" for a test set is not applicable.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of Human Reader Improvement with AI vs. Without AI Assistance
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for imaging or diagnostic AI products where human reader performance is being evaluated with and without AI assistance. The Bridge Plus Occlusion Balloon is a physical medical device for temporary vessel occlusion.
6. If a Standalone (i.e., Algorithm Only Without Human-in-the-Loop Performance) Was Done
No, a standalone (algorithm only) performance study was not done. This device is a physical medical instrument, not an algorithm.
7. The Type of Ground Truth Used
For this physical medical device, the "ground truth" is defined by engineering specifications, recognized industry standards (e.g., ISO for sterilization and biocompatibility), and performance benchmarks established by predicate devices. The device's physical and mechanical properties were tested against these pre-defined quantifiable criteria.
8. The Sample Size for the Training Set
The concept of a "training set" is not applicable to this physical medical device. Training sets are used for machine learning algorithms.
9. How the Ground Truth for the Training Set Was Established
Since there is no "training set" for this physical device, the method for establishing its "ground truth" is not applicable.

Re: K230281 Trade/Device Name: Picoclamp Regulation Number: 21 CFR 870.4450
Vascular |
| Classification Name: | Vascular clamp |
| Regulation: | 21 CFR §870.4450
A surgical instrument used to occlude a blood vessel temporarily.
PICOCLAMP is Ethylene Oxide sterile single-use hemostasis clamp consisting of Polyetheretherketone (PEEK) and stainless steel (SUS series). PICOCLAMP is designed for use during surgery to temporarily occlude blood vessels during the anastomosis process. PICOCLAMP consists of three main direct patient-contacting parts, all of them are streilized; main body, axis, and spring. The body is consisting of two parts; the jaw which is used to occlude the blood vessel temporarily and the grip which functions to open and close jaws using the surgeon hand or the clamp forceps. The axis integrates the body and keep its parts intact. The spring functions to give clamping force to the jaws. Two types of clamps are provided: green color clamps used for arteries temporary occlusion and blue color clamps used for veins temporary occlusion. Both of the artery and vein clamp are having two types: single and double. PICOCLAMP is available in three different sizes; S (Small), M (Medium), and L (Large). PICOCLAMP is used for temporary occlusion of blood vessels with diameters ranging from 0.2mm to 2.0mm. The clipping power applied at the blood vessel differs depending on the size of the clamp and the pressure of the spring selected. Once the anastomosis process is complete, PICOCLAMP is removed from the patient.
This document is a 510(k) Premarket Notification from the FDA regarding the PICOCLAMP vascular clamp. It outlines the device's characteristics, indications for use, comparison with a predicate device, and the performance data submitted to demonstrate substantial equivalence.
Based on the provided text, there is no information about acceptance criteria or a study proving the device meets those criteria in the context of AI/ML performance. The document is a regulatory approval for a physical medical device (vascular clamp), not a software or AI/ML-driven device.
Therefore, I cannot provide the requested information regarding acceptance criteria and a study proving device performance using AI/ML, as the document does not pertain to such a device or study.
The performance data mentioned in the document are for:
- Sterilization & Shelf-life & Packaging Testing: This ensures the device remains sterile and functional over its shelf life and that its packaging is adequate.
- Biocompatibility Testing: This ensures the materials used in the device are safe for contact with biological tissues.
- Bench Performance Testing: This evaluates the physical performance of the clamp, such as clipping power, ability for repeated opening/closing, and resistance to dislodgement. These tests compare the proposed device (PICOCLAMP) to the predicate device to demonstrate substantial equivalence of their physical performance.
The document explicitly states:
- "Animal Performance Testing was not required to demonstrate safety and effectiveness of the device."
- "Clinical Performance Testing was not required to demonstrate the safety and effectiveness of the device."
In summary, none of the requested information regarding AI/ML acceptance criteria, test set sizes, expert ground truth, MRMC studies, standalone algorithm performance, or training set details can be extracted from this document, as it is completely unrelated to AI/ML device performance.

| Product Code: | DXC |
| FDA Regulation Number: | 21 CFR 870.4450 |
The Abdominal Aortic and Junctional Tourniquet - Stabilized (AAJT-S) is indicated for use to control bleeding in the pelvis, inguinal area, axilla and for pelvic fracture stabilization.
The AAJT-S device is a wedge-shaped bladder that when inflated pushes in on the body Over the target area of application. One of the target areas is the lower abdomen, over the umbilicus, compressing all the structures within, including the descending aorta, to achieve the physiological effects of aortic compression. The other two areas are over the inguinal region or the axilla. In these two areas the region is compressed with the wedge- shaped bladder including the major vasculature that runs through that area.
Here's an analysis of the provided text regarding the acceptance criteria and study for the Abdominal Aortic and Junctional Tourniquet - Stabilized (AAJT-S):
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria | Reported Device Performance | Study to Prove |
|---|---|---|
| Pressure Maintenance: The AAJT-S must stay inflated and maintain the same pressure over the target area for at least a 4-hour period. | Confirmed successful inflation and pressure maintenance for at least a 4-hour period. | Pressure Testing |
| Component Bond Strength: The bonds of components to the hard cover must withstand normal tensile forces during clinical use. | Demonstrated ability to withstand normal tensile forces. | Force Testing |
| Biocompatibility (Cytotoxicity): No cytotoxic effects. | Passed ISO 10993-5 (in vitro cytotoxicity). | Biocompatibility Testing |
| Biocompatibility (Irritation & Skin Sensitization): No irritation or skin sensitization. | Passed ISO 10993-10 (irritation and skin sensitization). | Biocompatibility Testing |
| Wear Time (Stated Intended Use): Abdominal use: up to 1 hour; Junctional use: up to 4 hours. | Not explicitly stated as a test result, but the pressure test confirms the device maintains pressure for the maximum stated junctional use duration (4 hours). The increased wear time of 1 hour is also noted as a difference from the predicate device. | Pressure Testing implicitly supports junctional wear time. |
| Pelvic Fracture Stabilization: Indication for use. | Not explicitly stated what testing was conducted to prove this particular indication. The document refers to it as an "additional pelvic stability indication" compared to the predicate. | Not explicitly detailed in the provided text. |
Important Note: The provided text does not include specific numeric acceptance values (e.g., "maintain pressure within X mmHg of initial pressure"). It states the qualitative criteria and that the tests were performed to confirm or evaluate these criteria.
Missing Information:
- There are no explicit quantitative acceptance criteria or specific performance values reported for the pressure testing (e.g., pressure drop over time).
- Similarly, for force testing, no specific force values or deformation limits are given.
- The document doesn't detail how the "pelvic fracture stabilization" indication was specifically proven or what criteria were used for that.
2. Sample Size Used for the Test Set and Data Provenance
The provided text does not specify sample sizes for the performance tests (Pressure Testing, Force Testing, Biocompatibility Testing). It mentions these tests were "performed" but not the number of units or replicates used.
Data Provenance: Not applicable in the context of these non-clinical performance tests. These are laboratory tests conducted on the device itself, not patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable. These are non-clinical performance tests conducted on the device, not clinical studies involving expert interpretation of medical images or patient outcomes.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. The provided text describes non-clinical performance tests of the device itself (pressure, force, biocompatibility), not a clinical study involving human readers or comparative effectiveness with or without AI assistance. The device is a physical medical device (tourniquet), not an AI-powered diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, in the sense that the described tests are standalone device tests. The device's performance was evaluated independently without human-in-the-loop interaction as part of the test (beyond operating the test equipment). However, it's important to clarify that this refers to mechanical device performance, not AI algorithm performance.
7. The Type of Ground Truth Used
The "ground truth" for these non-clinical tests is based on objective physical measurements and established international standards:
- Pressure Testing: The ground truth is the measured pressure (e.g., using a pressure sensor) and its change over time.
- Force Testing: The ground truth is the applied force and the device's structural integrity under that force, measured by mechanical testing equipment.
- Biocompatibility Testing: The ground truth is determined by the results of standardized assays (e.g., cytotoxicity assays, irritation/sensitization tests) as per ISO 10993 standards.
8. The Sample Size for the Training Set
Not applicable. This device is a physical medical device, not an AI model that requires a training set.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As above, this is a physical device, not an AI model.

2. Sample size used for the test set and the data provenance
- Test Set Sample Size: Not explicitly stated for each bench test. The "In Vivo Testing" mentions an "acute Porcine model," implying a number of animals were used, but the specific count is not provided.
- Data Provenance: The bench testing and simulated use are laboratory-based, not patient data. The In Vivo testing was conducted using a Porcine (pig) model. The country of origin for the data is not specified, but the company is based in Salt Lake City, Utah, USA. The studies are prospective in nature, as they involve testing the manufactured device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. This device is a physical medical instrument, and its performance is assessed through engineering and biological in-vivo tests, not through expert interpretation of images or other data for diagnostic accuracy. "Ground truth" for this type of device relates to its physical performance meeting specifications (e.g., does the balloon burst at X pressure, does it occlude the vessel completely).
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable. As this isn't an algorithm or diagnostic study relying on human interpretation or consensus, there's no adjudication process as described (e.g., for reconciling differing expert opinions).
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 device does not involve AI assistance for human readers or interpretation of medical images.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for the device's performance in engineering and biological tests is derived from:
- Pre-defined engineering specifications and standards (e.g., pressure tolerances, material properties, dimensional accuracy).
- Observed physical and physiological responses in the animal model (e.g., successful occlusion, lack of damage to vessel walls, device integrity after deployment).
- Compliance with recognized standards like ISO 14971:2019 (risk analysis) and ISO 10993 (biocompatibility).
8. The sample size for the training set
Not applicable. This device is not an AI model requiring a training set.
9. How the ground truth for the training set was established
Not applicable. This device is not an AI model.

Trade/Device Name: GEM™ Biover Microvascular Clamps Regulation Number: 21 CFR 870.4450

GEM™ BIOVER disposable microvascular clamps are instruments which are used for all microsurgical procedures. They are used to occlude vessels during anastomosis, which is necessary as a result of vessel damage or thrombosis.
The GEM™ Biover Microvascular Clamps (Clamps) are arterial and venous clamps in both single and double clamp configurations, available in varying sizes. The clamps are sterile, disposable clamps for single use. The clamps are used in microsurgery, plastic surgery, and hand surgery for the temporary occlusion of blood vessels during an anastomosis.
The clamps are available for arteries and veins. The clamping force is higher for the arterial clamps than for the veinous clamps. The clamps are identified by a product reference code and by the color of the clamp. The clamps for veins are green, and the clamps for arteries are yellow.
The clamps are packaged individually in two Tyvek pouches (double pouched). The devices in the Tyvek pouches are gamma sterilized and are placed in cartons of 10. The clamps are used once and are disposed of after use.
This document is a 510(k) summary for the GEM™ Biover Microvascular Clamps, asserting their substantial equivalence to a previously cleared predicate device. This type of submission generally focuses on demonstrating that a new device is as safe and effective as a legally marketed predicate device, rather than proving performance against specific quantitative acceptance criteria in a robust statistical study.
Based on the provided text, the device is not an AI/ML powered device, nor is it a diagnostic device that requires high-level performance metrics, such as sensitivity, specificity, or AUC. The submission is for a physical medical device (microvascular clamps). Therefore, the information requested in the prompt regarding AI/ML performance metrics, sample sizes for test/training sets, expert adjudication, MRMC studies, and ground truth establishment is not applicable to this document.
The document states:
- "The GEM Biover microvascular clamps remain unchanged from the predicate device."
- "There are no engineering or performance changes to the device or its packaging."
The "performance data" section mentions:
- "The label design change and the outer carton sales unit design change were assessed and validated in a Packaging Summative Human Factors/Usability Study."
- "Historical complaint data were reviewed and indicate no use-related concerns, thus, there are no use-related risks or complaints that trigger a need for further Human Factors validation."
This indicates that the "performance" considered for this submission relates to packaging and user interface (labeling/carton design), and the study conducted was a human factors/usability study, not a clinical performance study measuring accuracy or efficacy of a medical algorithm.
Therefore, I cannot populate the table or answer the specific questions related to acceptance criteria, AI/ML performance, and ground truth for a diagnostic or AI-powered device, as these details are not present and are not relevant to this type of device submission.
