Q50 PLUS STENT GRAFT BALLOON CATHETER
The Stent Graft Balloon Catheter is intended for temporary occlusion of large vessels, or to expand vascular prostheses.
The OXMédical Stent Graft Balloon Catheter is a multi-lumen catheter which has a compliant polyurethane balloon with a maximum diameter of 50mm at 60cc inflation volume. The device is constructed with an 8Fr diameter blended PEBA shaft and is available in two usable lengths, 65 cm and 100 cm. The device is compatible with 12Fr (or larger) introducer sheaths and 0.038" diameter (or smaller) guidewires. Two platinum-iridium radiopaque marker bands are placed within the balloon to facilitate balloon placement prior to inflation. The proximal end of the catheter has an integral PEBA bifurcation manifold with female luer ports to allow communication with the balloon inflation lumen and guidewire lumen. A PVC extension tube (with stopcock) is connected to the balloon inflation port to facilitate handling. The device is a single use, sterile device.
This is a 510(k) premarket notification for a medical device (Q50® PLUS Stent Graft Balloon Catheter), not an AI/ML device. Therefore, the typical "acceptance criteria" and "study" information regarding device performance in an AI/ML context (such as accuracy, sensitivity, specificity, sample size, ground truth, expert consensus, MRMC studies, etc.) are not applicable here.
Instead, for a medical device like this, acceptance criteria typically refer to the specifications that the device must meet through various engineering, mechanical, and biological tests to demonstrate safety and effectiveness for its intended use, and substantial equivalence to a predicate device.
Here's how to interpret the provided information in the context of a 510(k) submission for a non-AI/ML medical device:
1. Table of Acceptance Criteria and Reported Device Performance
For this type of device, the "acceptance criteria" are the specifications that each mechanical, performance, and biocompatibility test must meet. The "reported device performance" is that "All tests met specifications."
Test Category | Specific Tests | Acceptance Criteria (Implied) | Reported Device Performance |
---|---|---|---|
Mechanical & Performance | Visual inspections | Meet design specifications (e.g., no defects) | Met specifications |
Dimensional inspections | Meet specified dimensions | Met specifications | |
Freedom from leakage | No leakage detected | Met specifications | |
Luer syringe compatibility | Compatible with luer syringes | Met specifications | |
Guidewire compatibility | Compatible with specified guidewire | Met specifications | |
Introducer sheath compatibility | Compatible with specified introducer sheath | Met specifications | |
Balloon compliance (volume v. diameter) | Meet specified compliance curve | Met specifications | |
Deflation time | Within specified time limits | Met specifications | |
Balloon inflation characteristics | Meet specified inflation characteristics | Met specifications | |
Radiopacity | Radiopaque markers visible | Met specifications | |
Corrosion resistance | No significant corrosion | Met specifications | |
Shipping/distribution testing | Maintained integrity after shipping simulation | Met specifications | |
Environment conditioning | Performed as expected after environmental conditioning | Met specifications | |
Vessel occlusion | Capable of occluding vessels up to 41mm | Met specifications (up to 41mm, as specified) | |
Balloon fatigue | Withstood 20 cycles of inflation (predicate spec) | Met specifications (maximum of 20 cycles) | |
Burst or leak volume | Withstood specified pressure/volume without bursting | Met specifications | |
Freedom from fragmentation | No fragmentation observed | Met specifications | |
Tensile strength (hub to shaft) | Met specified tensile strength | Met specifications | |
Tensile strength (tip to shaft) | Met specified tensile strength | Met specifications | |
Tensile strength (extension tube) | Met specified tensile strength | Met specifications | |
Torque strength | Met specified torque strength | Met specifications | |
Shelf life testing | Maintained function over specified shelf life | Met specifications | |
Package integrity | Maintained integrity | Met specifications | |
Biocompatibility | (Not detailed, but stated as "biocompatibility assessments") | Met biocompatibility standards | Met specifications (implied by "All tests met specifications") |
2. Sample Size Used for the Test Set and the Data Provenance
- Sample Size: The document does not explicitly state the sample sizes for each mechanical, performance, or biocompatibility test. Regulatory submissions for medical devices typically involve testing a statistically representative number of units for each test, but the exact numbers are not provided in this summary.
- Data Provenance: Not applicable in the context of an AI/ML algorithm's test set. The data provenance here would refer to the source of the physical devices tested (e.g., manufactured at QXMédical's facility). The testing is prospective for the submission, meaning tests were performed specifically for this device and submission.
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, not an AI/ML algorithm requiring expert-established ground truth for image or data interpretation. The "ground truth" for this device's performance is established by engineering and laboratory measurements against predefined specifications.
4. Adjudication Method for the Test Set
Not applicable. Adjudication methods like 2+1 or 3+1 are used for resolving discrepancies in expert interpretations (e.g., in medical image reading for AI/ML validation). The performance of this device is assessed directly through physical and chemical testing.
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. MRMC studies are specifically designed to assess the impact of AI on human reader performance, which is not relevant for a physical catheter.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This is a physical device, not an algorithm.
7. The Type of Ground Truth Used
The "ground truth" for this medical device is the adherence to established engineering specifications, material properties, and performance benchmarks as defined by relevant industry standards and internal design requirements. This is verified through:
- Direct physical measurement (e.g., dimensions, compliance, tensile strength).
- Functional testing (e.g., inflation, deflation, occlusion, compatibility).
- Biocompatibility assessments (following ISO standards, often involving chemical analysis and biological assays).
8. The Sample Size for the Training Set
Not applicable. This is a physical device, not an AI/ML algorithm that requires a training set.
9. How the Ground Truth for the Training Set was Established
Not applicable. See point 8.
In summary, the provided information details a traditional medical device 510(k) submission, not an AI/ML device. The "study" proving the device meets acceptance criteria is the comprehensive non-clinical testing program described, which demonstrated that all aspects of the device's mechanical function, performance, and biocompatibility met the defined specifications and showed substantial equivalence to the predicate device.

STENT GRAFT BALLOON CATHETER
The Stent Graft Balloon Catheter is intended for temporary occlusion of large vessels, or to expand vascular prostheses.
The Stent Graft Balloon Catheter is a multi-lumen catheter which has a compliant polyurethane balloon with a maximum diameter of 50mm. The device is available in two usable lengths, 65 cm and 100 cm. The device is designed to accommodate a 0.038" diameter or smaller guidewire. Two radiopaque marker bands are placed within the balloon to facilitate balloon placement prior to inflation. The device is a single use, sterile device.
This document is a 510(k) summary for a medical device (Stent Graft Balloon Catheter). It describes the device, its intended use, and states that it underwent non-clinical testing to verify its safety and effectiveness.
However, this document does not contain the specific information requested in your prompt regarding acceptance criteria and a study proving the device meets those criteria.
Here's why and what information is missing:
- No Acceptance Criteria or Performance Data Table: The document explicitly states "No performance standards applicable to this product have been developed under Section 514 of the Act." While "mechanical, performance, and biocompatibility testing" were done, specific acceptance criteria for these tests (e.g., burst pressure, fatigue life) and the actual numerical results from these tests are not provided.
- No Description of a Clinical Study: The document refers to "non-clinical testing" which typically means bench testing and potentially animal studies, not human clinical trials. There is no mention of:
- Sample sizes for test sets (human patients).
- Data provenance (country of origin, retrospective/prospective).
- Number or qualifications of experts for ground truth.
- Adjudication methods.
- Multi-reader multi-case (MRMC) comparative effectiveness studies.
- Standalone algorithm performance.
- Type of ground truth used (pathology, outcomes data).
- Sample size for training sets (as this is not an AI/algorithm-based device).
- How ground truth for a training set was established.
Therefore, I cannot fulfill your request for the specific details outlined in your prompt based solely on the provided text. The document is a regulatory submission demonstrating substantial equivalence to predicate devices, primarily through non-clinical testing, rather than a detailed report of a study involving clinical performance acceptance criteria.
