Deknatel® Deklene® MAXX™ Polypropylene Surgical Sutures are indicated for use in general soft tissue approximation and/or ligation, including use in cardiovascular, and neurological procedures, but not for use in ophthalmic procedures.

Deknatel® Deklene® Maxx™ Polypropylene Suture is a nonabsorbable, sterile surgical suture composed of a strand of polypropylene, a synthetic linear polyolefin. Deknatel® Deklene® MAXX™ Polypropylene Surgical Suture is available dyed (blue) or undyed (colorless).

Deknatel® Deklene® Maxx™ Polypropylene Surgical Suture meets all nonabsorbable surgical suture requirements established by the United States Pharmacopeia (USP) except for suture sizes 7-0 and 8-0 which differ from USP in diameter only.

Deknatel® Deklene® Maxx™ Polypropylene Surgical Suture is available in USP sizes 8-0 through 0. The suture is provided in a variety of lengths, with and without 300 or 400 series stainless steel needles, with and without PTFE felt pledgets, and may be supplied in a variety of cut lengths. Finished suture may be packaged in cartons as single packs, multipacks or procedure packs.

The provided text is a 510(k) summary for a medical device (surgical suture) and does not contain information about the acceptance criteria or a study proving that an AI device meets acceptance criteria. The document explicitly states: "No clinical trials were conducted."

Therefore, I cannot extract the requested information regarding AI device performance.

Gabbay-Frater™ is a device for organizing, arranging and counting multiple interrupted sutures in an orderly fashion.

Deknatel Nonabsorbable Surgical Sutures are available in five (5) different material options.

• 1. Poly(ethylene terephthalate) a polyester fiber.
  • The three types of polyester sutures are 'cottony'™ II, 'silky' II POLYDEK, and ● TEVDEK II. 'cottony' II is uncoated polyester suture. 'silky' II POLYDEK® suture has a light coating of Polytetrafluoroethylene (PTFE) and TEVDEK II has a heavy PTFE coating.
  • . NextStitch Cardiovascular Valve Suture is a combination of 'silky' II POLYDEK and/or TEVDEK II polyester suture. NextStitch is a continuous chain of linked sutures designed to provide an alternative suturing technique for cardiovascular valve replacement procedures.
• 2. Polypropylene: DEKLENE II and DEKLENE® MAXX are the two varieties of this material.
• 3. NYLON is composed of monofilament synthetic polyamide fiber.
• 4. SILK is composed of grade 4A Chinese silk derived from the domesticated species Bombyx mori (B mori) of the family Bombycidae.
• 5. STERNOTOMY STAINLESS STEEL sutures are composed of 316 LVM stainless steel.

All sutures are provided in a variety of lengths, with and without needles, and (if applicable) with and without pre-attached pledgets (if applicable).

An accessory that can be used with the Nonabsorbable Surgical Sutures is the Gabbay-Frater Suture Guide which is a convenient suture organizer which keeps suture ends tangle-free.

This document is a 510(k) summary for the Deknatel Nonabsorbable Surgical Sutures. It aims to demonstrate substantial equivalence to previously cleared predicate devices, primarily focusing on a shelf-life extension and ownership transfer. Clinical performance criteria or studies in the context of device accuracy for diagnosis or treatment are not applicable here, as this is a surgical suture, not a diagnostic or AI-powered device.

Therefore, the requested information elements such as acceptance criteria, reported device performance, sample size for test sets, data provenance, expert involvement, adjudication methods, MRMC studies, standalone performance, types of ground truth, and training set details are not applicable or available in this submission because the device is a surgical suture, not an AI-powered diagnostic tool.

The "acceptance criteria" and "study" described in the document relate to the physical and mechanical properties of the sutures and their packaging for shelf-life extension, not to diagnostic or performance accuracy in the way an AI medical device would be evaluated.

Here's the relevant information based on the provided document regarding the substantiation of the shelf-life extension:

1. Table of Acceptance Criteria and Reported Device Performance:

The document states that non-clinical real-time aging testing was performed in accordance with specific standards. However, it does not explicitly present a table of acceptance criteria alongside reported device performance values in a comparative format for each individual suture property. Instead, it broadly states that "the proposed Deknatel Nonabsorbable Surgical Sutures are substantially equivalent to the predicate devices."

The standards referenced imply the properties that were measured and thus, the implicit acceptance criteria would be compliance with these standards within expected ranges for surgical sutures.

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

• Sample Size: The document does not specify the exact sample size used for the real-time aging testing. It generally refers to "non-clinical real-time aging testing."
• Data Provenance: The data is non-clinical, likely generated in a laboratory setting by Teleflex Medical, Inc. or its contractors. The document does not specify country of origin for the data, but the company is based in Morrisville, NC, USA. The testing is prospective in the sense that the sutures were aged in real-time to assess performance over 5 years.

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

• Not Applicable. For the physical and mechanical testing of surgical sutures, ground truth is established by adherence to recognized international and national standards (e.g., ISO, USP) and laboratory testing protocols, not by expert consensus or interpretation of images. The "ground truth" is the objective measurement against these standards.

4. Adjudication Method for the Test Set:

• Not Applicable. Adjudication methods like 2+1 or 3+1 are typically used for subjective evaluations where human interpretation is involved, such as reading medical images. For physical property testing of sutures, measurements are objective and usually do not require adjudication.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done:

• No. This is not an AI-powered diagnostic device, so MRMC studies are not relevant.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

• Not Applicable. This is a physical medical device (suture), not an algorithm or AI.

7. The Type of Ground Truth Used:

• Objective Measurement against Recognized Standards: The "ground truth" for demonstrating the shelf-life and performance of the sutures are the established specifications and test methods outlined in ISO and USP standards for medical device packaging and surgical sutures.

8. The Sample Size for the Training Set:

• Not Applicable. This is not an AI device that requires a "training set." The performance data is for physical characteristics of the manufactured product.

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

• Not Applicable. As there is no "training set," this question is not relevant.

In summary, this 510(k) pertains to a traditional physical medical device (surgical suture). The "study" referenced is non-clinical real-time aging testing to support a shelf-life claim, using recognized industry standards for material properties and packaging integrity. The concepts of acceptance criteria, test sets, experts, and ground truth are applied differently in this context compared to AI/diagnostic devices.
