The Zenysis™ Short-Term Dialysis Catheter, is indicated for use in attaining short-term (less than 30 days) vascular access for hemodialysis, hemoperfusion, and apheresis treatments. The catheter is intended to be inserted in the jugular, femoral, or subclavian vein as required.

Zenysis™ Short-Term Dialysis Catheters are made of thermosensitive polyurethane, which softens when exposed to body temperature. The catheter is divided into two separate lumens permitting continuous blood flow. Both the venous (blue) and the arterial (red) lumens may be used for hemodialysis, hemoperfusion, and apheresis treatments. The Attachable Suture Wing and Attachable Suture Wing Fastener will be used to support the Zenysis™ Short-Term Dialysis Catheter, as securement devices to fixate the exposed portion of the catheter shaft to the patient's skin. The subject device included in this submission will be offered in varying French size and catheter configuration types, as summarized in the table below: Straight Extension Legs and Precurved Extension Legs with Insertion Lengths of 12.5 cm, 15 cm, 20 cm, and 24 cm. The subject catheters will be packaged with legally marketed components used in the placement procedure.

The provided text describes the Zenysis™ Short-Term Dialysis Catheter and its substantial equivalence to a predicate device. However, it does not contain a study that proves the device meets specific acceptance criteria in the way a clinical or performance study with detailed statistical results would.

Instead, the document outlines the acceptance criteria by referencing various guidance documents and standards that the device was tested against. The study itself is a series of verification tests performed in accordance with Design Controls (21 CFR §820.30) and the listed standards. The "reported device performance" is simply stated as "The subject device met all predetermined acceptance criteria".

Here's the information extracted and formatted to answer your request, with "N/A" for information not present in the document.

1. Table of Acceptance Criteria and Reported Device Performance

Note: The document states that the "subject device met all predetermined acceptance criteria derived from the above listed references and demonstrated substantially equivalent performance as compared to the cited predicate device." It does not provide specific numerical results for each test.

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not specified.
• Data Provenance: Not specified (e.g., country of origin). The testing would typically be performed in a laboratory setting by the manufacturer (Bard Access Systems, Inc. in Salt Lake City, UT).
• Retrospective or Prospective: N/A (these are bench tests, not clinical studies on patients).

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

• Number of Experts: N/A. Ground truth for these types of bench tests is established by adhering to widely accepted engineering and medical device standards (e.g., ISO, ASTM) and internal protocols, rather than expert consensus on medical images or diagnoses.
• Qualifications of Experts: N/A.

4. Adjudication Method for the Test Set

• Adjudication Method: N/A. The evaluation methods for these bench tests are typically predefined by the relevant standards and protocols, not requiring an adjudication process like clinical expert review.

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

• N/A. This document describes a medical device (dialysis catheter), not an AI-powered diagnostic or assistive tool. Therefore, an MRMC study comparing human readers with and without AI assistance is not applicable.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study Was Done

• N/A. This document describes a physical medical device, not an algorithm.

7. The Type of Ground Truth Used

• Type of Ground Truth: Established definitions and metrics based on engineering principles and international standards (e.g., ISO 10555, ASTM F640, ISO 10993-1) for device performance, safety, and material properties.

8. The Sample Size for the Training Set

• N/A. This is a physical medical device; there is no "training set" in the context of machine learning or AI.

9. How the Ground Truth for the Training Set Was Established

• N/A. As there is no training set, this is not applicable.
