Intended Use

The DuraSheath Introducer Sheath System is indicated to be used for introduction of interventional and diagnostic devices into the peripheral (and coronary) vasculature. The device is also intended to be used within a pediatric population.

Device Description

The DuraSheath Introducer Sheath System is a sterile, disposable device consisting of (a) a coil reinforced shaft with an atraumatic tip at the distal end; (b) a hemostasis valve with a side port and color coded 3-way stopcock; and (c) a tapered tip dilator with snap-fit hub at the proximal end.

AI/ML Overview

The provided text describes a 510(k) premarket notification for a medical device called the DuraSheath Introducer Sheath System. It details the device's design, materials, indications for use, and a comparison to predicate devices, along with non-clinical performance data.

However, the document does not contain acceptance criteria or study details in the format requested, which typically relates to performance metrics for AI/ML devices or clinical endpoints for studies proving substantial equivalence. Instead, it lists various engineering and biological tests conducted to demonstrate the safety and effectiveness of the device as a whole, rather than specific performance metrics against pre-defined acceptance thresholds for an AI algorithm.

The document mainly focuses on proving the new device is substantially equivalent to existing, legally marketed devices. It details a comprehensive set of non-clinical tests (mechanical, biocompatibility, sterilization, accelerated aging, packaging integrity, simulated use, and usability) to demonstrate this equivalence and the device's safety and effectiveness.

Given the nature of the device (an introducer sheath system, which is a physical medical device, not an AI/ML algorithm or a diagnostic tool with specific performance metrics like sensitivity/specificity), the requested information regarding "acceptance criteria and the study that proves the device meets the acceptance criteria" in terms of AI performance, expert ground truth, adjudication methods, MRMC studies, and standalone algorithm performance is not applicable.

Therefore, I cannot populate the table and answer the specific questions (2-9) about acceptance criteria, test set sample size, expert qualifications, adjudication, MRMC studies, standalone performance, ground truth types, and training set details because this information is not present in the provided FDA document, as it pertains to a mechanical medical device, not an AI/ML diagnostic or therapeutic device.

The closest information to "acceptance criteria" is the list of standards the device testing conformed to, indicating that meeting these standards served as the "acceptance criteria" for demonstrating safety and effectiveness of a physical medical device. The "study that proves the device meets the acceptance criteria" is the collection of all the non-clinical tests listed in the "PERFORMANCE DATA" section.

Here's what can be extracted from the provided text, recognizing the constraints:

2. Sample size used for the test set and the data provenance: Not applicable in the context of an AI/ML device. For the mechanical device, the number of units tested for each specific non-clinical test (e.g., how many sheaths were subjected to pull-out testing) is not explicitly stated, although it is implied that sufficient units were tested to meet the requirements of the listed standards. There was feedback from 16 clinical cases in Germany, but this was for European CE certification and not a formal clinical trial for this 510(k).

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth, in the AI/ML context, does not apply to this mechanical device.
