The Inion Trinion™ Biodegradable Meniscus Screw is indicated for use in the fixation of longitudinal vertical meniscus lesions (bucket handle) located in the vascularized area of the meniscus (red-red and red-white areas).

Device Description

The Inion Trinion™ Biodegradable Meniscus Screw is intended for use in the fixation of longitudinal vertical meniscus lesions (bucket handle) located in the vascularized area of the meniscus (red-red and red-white areas). Screws are offered in different lengths typical for this application. The system will be provided sterile to the user and is not to be re-sterilized. The Inion Trinion™ Biodegradable Meniscus Screw is designed to be used with customized instrumentation. The Inion Trinion™ Biodegradable Screw is made of resorbable polylactic acid / trimethylenecarbonate copoylmers [Poly (L-lactide-co-D,L-lactide) and poly (L-lactide-cotrimethylenecarbonate)]. The Inion Trinion™ Biodegradable Meniscus Screws are offered both undyed and coloured for better visualization during surgical operation. The Trinion™ Biodegradable Meniscus Screw gradually looses its strength during 18-36 weeks. Bioresorption takes place within two to three years.

AI/ML Overview

I apologize, but this document does not contain the specific information required to complete your request. The provided text is a 510(k) summary for a medical device (Inion Trinion™ Biodegradable Meniscus Screw) and primarily focuses on its equivalence to previously marketed products rather than detailed performance studies and acceptance criteria as you've requested.

Specifically, the document does not include:

A table of acceptance criteria and reported device performance.
Information on sample sizes for test sets, data provenance, or expert qualifications for ground truth.
Details on adjudication methods.
Information about multi-reader multi-case (MRMC) comparative effectiveness studies or standalone algorithm performance.
Details on the type of ground truth used beyond a general statement of "clinical success" for predicate devices.
Sample size for training sets or how ground truth for training sets was established.

This document describes the device, its intended use, and argues for its substantial equivalence to predicate devices based on material properties and biomechanical testing. It is a regulatory submission, not a detailed scientific study report with the kind of performance metrics you've asked for.

DEVICE DESCRIPTION AND PRINCIPLES OF OPERATION

The Inion Trinion™ Biodegradable Meniscus Screw is intended for use in the fixation of I he Infon Trinon - Diodcepadable Monised - Decated in the vascularized area of the longhudmal vertion membeds renoms ( Screws are offered in different lengths typical for this application. The system will be provided sterile to the user and is not to be re-sterilized. this upplication. " The oyengiscus Screw is designed to be used with customized instrumentation.

The Inion Trinion™ Biodegradable Screw is made of resorbable polylactic acid / trimethylenecarbonate copoylmers [Poly (L-lactide-co-D,L-lactide) and poly (L-lactide-cotrimethylenecarbonate)]. The Inion Trinion™ Biodegradable Meniscus Screws are offered both undyed and coloured for better visualization during surgical operation. The Trinion™ Biodegradable Meniscus Screw gradually looses its strength during 18-36 weeks. Bioresorption takes place within two to three years.

EQUIVALENCE TO MARKETED PRODUCTS

The properties of the Inion Trinion™ Biodegradable Meniscus Screw are substantially equivalent to those of the previously accepted and clinically successfully used biodegradable meniscal repair devices.

Inion Trinion™ Biodegradable Meniscus Screw, Innovasive Meniscal Screw (Mitek Clearfix), LactoSorb Meniscal Screw, BioStinger -V Bioabsorbable Meniscal Repair Device and Biofix Biodegradable Meniscus Arrow System have the same intended use and principles of operation and very similar design characteristics. Biomechanical testing demonstrates that the device is substantially equivalent to the predicate ones. Differences between The Inion Trinion™ Biodegradable Meniscus Screw and predicate devices do not raise new questions of safety and effectiveness.

Regulation Number and Section

§ 888.3040 Smooth or threaded metallic bone fixation fastener.

(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.
