AxoGen Nerve Cap is indicated to protect a peripheral nerve end and to separate the nerve from surrounding environment to reduce the development of symptomatic or painful neuroma.
The AxoGen Nerve Cap is a surgical implant that is a tubular device with one open end, one sealed end (cap) and internal channels designed to provide protection for a peripheral nerve end or stump where repair is unattainable or not desired. The device prevents dislocation of the nerve end by pulling the nerve into the tube, suturing the nerve within the cap, and securing the tab to the surrounding tissue.
AxoGen Nerve Cap is an extracellular matrix (ECM) and is fully remodeled during the healing process. The device is manufactured from processed porcine small intestinal submucosa (SIS) which is vacuum pressed prior to packaging. After hydration, the device is easy to handle, soft, pliable, non-friable and porous.
AxoGen Nerve Cap is flexible to accommodate movement of the joints and surrounding soft tissues and has sufficient mechanical strength to hold appropriately sized nonabsorbable suture. It is supplied in nominal tube diameters ranging from 1.5mm up to 8mm, and a length of 13mm-38mm. AxoGen Nerve Cap is provided sterile, for single use only, and in a variety of sizes to meet clinical needs.
The provided text describes the AxoGen Nerve Cap, a medical device, and its journey through the 510(k) premarket notification process for FDA clearance. The submission focuses on demonstrating substantial equivalence to predicate devices based on various performance specifications and biocompatibility testing.
However, the provided text does not contain any information related to a study involving human or expert readers, AI assistance, complex ground truth establishment for a test or training set, or sample sizes related to such studies. The performance specifications primarily relate to the physical and biological properties of the device itself (e.g., suture retention strength, tensile strength, biocompatibility, usability in a handling context).
Therefore, I cannot fulfill most of your request as the information is not present in the provided document. I can only extract criteria and performance related to the physical device.
Here's what I can provide based on the given text:
Acceptance Criteria and Reported Device Performance for AxoGen Nerve Cap

Sterilization
The AxoGen Nerve Cap is sterilized using an established ethylene oxide (EO) sterilization cycle that has been validated to a sterility assurance level (SAL) of 10th in conformance with EN ISO 11135:2014: Sterilization of Health Care Products - Ethylene Oxide - Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices.
Using the exhaustive extraction technique, the EO residuals for AxoGen Nerve Cap samples were verified to be less than the maximum allowable limits as defined by ISO 10993-7:2008, Biological evaluation of medical devices - Part 7: Ethylene oxide sterilization residuals:
Non-clinical Testing
An animal study evaluating porcine small intestine submucosa (SIS) nerve end caps in a chronic rat tibial nerve transposition (TNT) model evaluated the safety, local effects. and overall efficacy of AxoGen Nerve Caps in the reduction of painful neuroma formation. Control groups were also implanted and included a hollow tube conduit nerve cuff with an open end and a surgical control. Overall, AxoGen Nerve Caps (both Partition and Spiral) and Open Tubes nerve cuffs had similar tissue and inflammatory responses at 56 and 84 days. Furthermore, AxoGen Nerve Caps (both Partition and Spiral) were partially remodeled, but still present at 84 days post-surgery. As compared to the Surgical Controls, the Nerve Caps provided containment of nerve end and subsequent outgrowth, a reduction in nerve width measurements, and overall reduced sensitivity to mechanical stimulation, indicating a reduced likelihood of symptomatic and painful neuroma formation.
Substantial Equivalence
The AxoGen Nerve Cap is similar in intended use, design and function to the predicate device, the Polyganics Nerve Capping Device (Neurocap) cleared under 510(k) K152684. The technological similarities and differences (e.g., technological features, dimensions, materials, Intended Use, etc.) between the AxoGen Nerve Cap and the Polyganics Neurocap devices are shown in Table 3.
The primary differences include material differences, internal channels, end cap design, more sizes for the AxoGen Nerve Cap. The materials used in both devices are standard nerve cuff materials used in multiple nerve cuff products on the market today. Both devices have internal chambers/channels to reduce neuroma formation by
{3}------------------------------------------------
containing the nerve end and subsequent outgrowth. Both devices can be sutured to surrounding structures to hold the nerve cap device in place after implantation. Both devices have a variety of sizes allowing the surgeon to size match the proximal nerve stump. The difference in Intended Use (addition of pain to the Indication For Use statement) is supported by AxoGen's preclinical study. These differences in technological characteristics do not raise safety or effectiveness issues as both devices are designed to cap the end of a proximal nerve to reduce neuroma formation by containing the nerve end and subsequent outgrowth with the ability to attach the device to surrounding tissue.

The AxoGen Nerve Cap is similar in material, design, manufacturing (including packaging and sterilization method) as the Surgisis Nerve Cuff (distributed as the AxoGuard® Nerve Connector) cleared under 510(k) K031069 and K162741. The technological similarities and differences (e.g., Indications for Use, manufacturing forming process, dimensions, material, and mechanism of use) between the AxoGen Nerve Cap and the Surgisis Nerve Cuff devices are shown in Table 4.
The Surgisis Nerve Cuff is a material predicate and not a device function predicate. The AxoGen Nerve Cuff has a different Indication For Use from the Surgisis Nerve Cuff. However both devices are used with peripheral nerve repair while achieving different purposes. There is a difference in materials, (SIS 1.0 for Surgisis Nerve Cuff versus SIS 2.0 for AxoGen Nerve Cap). Both materials are well-known and characterized materials (SIS material) and are considered equivalent. The output of the manufacturing process (device form) is different, but the manufacturing process itself is equivalent with respect to raw materials and process controls.
These differences in technological characteristics do not raise safety or effectiveness issues as both devices are designed for peripheral nerve repair and are manufactured in an equivalent manner.
