Intended Use
Reinforced Flexible Collagen Nerve Cuff is used for the management of peripheral nerve injuries where gap closure can be achieved by flexion of the extremity (e.g., to prevent ingrowth of scar tissue).
Device Description
Reinforced Flexible Collagen Nerve Cuff is a resorbable, flexible type I collagen tubular matrix circumferentially supported with a resorbable synthetic polymer filament. The device provides both an encasement for peripheral nerve injuries as well as protection of the neural environment. The synthetic polymer filament provides enhanced support for biomechanical stability and kink-resistance of the collagen conduit. The Reinforced Flexible Collagen Nerve Cuff is an interface between the nerve and the surrounding tissue to prevent ingrowth of scar tissue. When implanted at a severed peripheral nerve gap, the Reinforced Flexible Collagen Nerve Cuff provides guidance for axonal growth across the gap. Upon hydration, the Reinforced Flexible Collagen Nerve Cuff is a soft, flexible collagen conduit with compression-resistant and kink-resistant properties. It is supplied sterile, nonpyrogenic, in various sizes and for single use only.
More Information

No
The description focuses on the material properties and mechanical function of a collagen nerve cuff, with no mention of AI or ML capabilities.

Yes.
The device is used for the management of peripheral nerve injuries by providing an encasement and protection for the neural environment, guiding axonal growth, and preventing scar tissue ingrowth, which collectively contribute to the repair and healing of nerve injuries.

No

Explanation: The device description and intended use clearly state that the Reinforced Flexible Collagen Nerve Cuff is a surgical implant designed to physically support and protect damaged peripheral nerves, guiding axonal growth and preventing scar tissue ingrowth. It does not perform any diagnostic function, such as identifying, measuring, or analyzing medical conditions or biological processes.

No

The device description clearly describes a physical, implantable medical device made of collagen and synthetic polymer, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Reinforced Flexible Collagen Nerve Cuff is an implantable device used to physically support and protect damaged peripheral nerves within the body. It acts as a conduit and barrier to aid in nerve regeneration.
  • Intended Use: The intended use clearly states it's for the "management of peripheral nerve injuries" and is implanted to "prevent ingrowth of scar tissue" and "provide guidance for axonal growth." This is a therapeutic and structural function, not a diagnostic one based on analyzing bodily specimens.

The description and intended use clearly indicate this is an implantable medical device used for surgical repair and support, not for in vitro diagnostic testing.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Nonclinical Tests Submitted: The substantial equivalence of the Reinforced Flexible Collagen Nerve Cuff to its predicate device was demonstrated based on an evaluation of the product safety, product characteristics, and performance in an animal model. In vitro characterization studies included evaluation of physical properties such as suture pullout strength, compression resistance, kink resistance, and an evaluation of physicochemical properties such as product permeability and hydrothermal transition temperature. The characterization test results of the subject device were equivalent to those of the predicate device. The Reinforced Flexible Collagen Nerve Cuff subject device was evaluated in a number of in vitro and in vivo tests to assess its safety/biocompatibility. The subject device passed all applicable tests in accordance with ISO 10993-1 and FDA Guidance on Use of International Standard ISO 10993-1 for the biological evaluation of medical devices within a risk management process.

Animal Study: 48 rats underwent excision of a segment of the sciatic nerve. In 16 of 48 rats, the nerve injuries were treated with the subject device, in another 16 rats the nerve injuries were treated with the predicate device, and in the remaining 16 rats, the nerve injuries were treated with an autograft control. Animals were sacrificed at 12 weeks and 24 weeks. The nerve repair segments were evaluated by gross observation, histological, and histomorphometrical methods. The study demonstrated that nerve regeneration was robust for both the subject and predicate devices.

Animal Study

In the animal study conducted, 48 rats underwent excision of a segment of the sciatic nerve. In 16 of 48 rats, the nerve injuries were treated with the subject device, in another 16 rats the nerve injuries were treated with the predicate device, and in the remaining 16 rats, the nerve injuries were treated with an autograft control. There were no procedure related complications or premature deaths in the study.

Animals were sacrificed at 12 weeks and 24 weeks. The nerve repair segments were evaluated by gross observation, histological, and histomorphometrical methods. The study demonstrated that nerve regeneration was robust for both the subject and predicate devices.

Conclusions Drawn from Non-clinical Studies

Subject and predicate device performance data were compared to support the safety of the subject device and demonstrate that the Reinforced Flexible Collagen Nerve Cuff should perform as intended in the specified use conditions.
