The M-Y Sheath is intended to enable delivery of interventional and diagnostic devices into the human vasculature, excluding coronary and neuro vasculature.
The M-Y Sheath is a contralateral access guiding sheath with a proximal hemostatic valve and an integrated fixed wire at its distal end. The fixed wire is attached to the sidewall of the sheath and extends beyond the distal tip of the sheath and is used to provide sheath support during use. The wire distal end is first introduced through the ipsilateral in-dwelling femoral sheath introducer. then snared and externalized through an in-dwelling contralateral sheath introducer, thereby allowing the sheath to be positioned over the bifurcation by gentle simultaneous pushing and pulling the device using a "flossing" technique. Once the M-Y sheath tip is positioned at the desired location in the contralateral vasculature. the wire can be externally secured (e.g. using a pin vise), thereby providing stability and support when advancing interventional tools (e.g. angioplasty balloons, stents, etc.). The M-Y Sheath is compatible to fit through a standard 7 French femoral sheath introducer placed in the ipsilateral leg. The M-Y Sheath luminal diameter is sized to be compatible with 5 French therapeutic and diagnostic devices.
The document provided describes the M-Y Sheath, a catheter introducer, and its performance testing for a 510(k) premarket notification (K190369).

- In-vitro 3-D anatomy simulation model: Does not specify sample size (e.g., number of devices tested, number of simulated procedures).
Data Provenance: The studies are described as "bench testing," "in-vitro," and "clinical simulation bench model," indicating laboratory or simulated environments, not human clinical trials. The origin is implicitly the manufacturer (RAM Medical Innovations, Inc.) or its contracted testers. The data is retrospective in the sense that it was collected prior to this submission, but it's not data from patient records.
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 not an AI/ML device that requires ground truth established by medical experts. The testing involves physical properties, material compatibility, and functional performance in simulated environments. The "ground truth" for these tests is based on engineering specifications, recognized standards (ISO), and observable physical outcomes (e.g., "Pass/Fail," successful deployment, absence of leakage).
4. Adjudication Method for the Test Set
Not applicable. As noted above, this is not an AI/ML device requiring expert adjudication of results. The tests have objective pass/fail criteria.
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 is a physical medical instrument (catheter introducer), not an AI-powered diagnostic or assistive tool for human readers. No MRMC study was conducted.
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
The "ground truth" used for this device's testing is based on:
- Engineering specifications and design requirements: For mechanical performance, dimensions, and visual requirements.
- International Standards (ISO): Specifically ISO 10993 (biocompatibility), ISO 11135-1 (sterilization), and ISO 594-2 (hub/luer fittings).
- Objective physical measurements and observations: For leakage, tensile strength, fracture, flexing, radiopacity, corrosion, etc.
- Pre-defined acceptance criteria: For the successful completion of simulated use and clinical simulation models.
8. The Sample Size for the Training Set
Not applicable. This device does not involve a "training set" as it is not an AI/ML algorithm.

The Raider guidewire is intended for use in percutaneous procedures to introduce and position catheters and other interventional devices within the coronary and peripheral vasculature.
The Raider guidewire is a stainless steel core guidewire with a maximum outer diameter of 0.014″ and a straight, shapeable tip. It is available in 190 cm and 300 cm length is compatible with a guidewire extension. The distal portion of the guidewire includes a radiopaque coil and is covered with a polymer jacket and hydrophilic coating. The proximal portion has a PTFE coating.
The provided text is a 510(k) summary for the Raider Guidewire. It outlines the device's indications, technological characteristics, and testing performed to demonstrate substantial equivalence to a predicate device. However, this document does not contain the kind of detailed information about acceptance criteria or a study design (like sample size for test sets, data provenance, expert demographics, adjudication methods, MRMC studies, or standalone algorithm performance) that you would typically find for an AI/ML medical device.
The Raider Guidewire is a physical medical device (a catheter guide wire), not an AI/ML software device. Therefore, the questions posed in the prompt, which are highly specific to the evaluation of AI/ML diagnostic or predictive algorithms, are not applicable to the information provided in this 510(k) summary.
The document discusses "acceptance criteria" in a general sense through performance testing for mechanical properties and biocompatibility.
