Indications for Use
The Nerve Capping Device is indicated to protect a peripheral nerve end and to separate the nerve from surrounding environment to reduce the development of a symptomatic neuroma.
Device Story
The Nerve Capping Device is a sterile, single-use, bioresorbable tubular implant composed of poly(DL-lactide-co-ε-caprolactone). It features one open end and one sealed end with a fixation hole. Used by surgeons in a clinical setting, the device is placed over a peripheral nerve stump to isolate it from the surrounding environment. The nerve end is pulled into the tube and sutured; the sealed end is then sutured to surrounding tissue. By providing a physical barrier for up to 10 weeks, the device prevents nerve stump dislocation and reduces the formation of symptomatic neuromas. The device is provided in various diameters to accommodate different nerve sizes.
Clinical Evidence
Bench testing only. Evidence includes biocompatibility testing (cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility, implantation/local tolerance, degradation, genotoxicity, carcinogenicity), in vitro degradation assessment, suture retention strength testing, tip dimensional verification, and usability testing with intended end users. Results demonstrate the device is non-pyrogenic, biocompatible, and maintains barrier function for up to 10 weeks, consistent with predicate performance.
Technological Characteristics
Material: poly(DL-lactide-co-ε-caprolactone) (synthetic bioresorbable copolyester). Form factor: tubular device with one closed end, 3cm length, various diameters (1.5mm–8.0mm). Barrier function: non-permeable for up to 10 weeks. Sterilization: Ethylene oxide (SAL 10^-6). Mechanical: suture-fixable. Packaging: Polycarbonate tray and Tyvek pouch.
Indications for Use
Indicated for patients requiring protection of a peripheral nerve end to reduce the development of a symptomatic neuroma.
Regulatory Classification
Identification
A nerve cuff is a tubular silicone rubber sheath used to encase a nerve for aid in repairing the nerve (e.g., to prevent ingrowth of scar tissue) and for capping the end of the nerve to prevent the formation of neuroma (tumors).

## Device Description:
The Nerve Capping Device is a sterile biodegradable nerve cuff composed of the bioresorbable copolyester poly(DL-lactide-s-caprolactone). It is a tubular device with one open end and one sealed end which functions as a cap, isolating the nerve end. The capping device prevents dislocation of the stump by pulling the nerve end into the tube and suturing in the nerve within the cap. Consequently, the end of the cap will be sutured to surrounding tissue. One hole at the sealed end of the tube allows easy fixation with a suture to the surrounding tissue. The size of the product is 3cm in length, and is available in
{4}------------------------------------------------
different diameters for different sized nerves. The Nerve Capping Device is sterilized in a pouch package. The device is single-use, cannot be re-sterilized, and is a prescription product.
Indications for Use:
The Nerve Capping Device is indicated to protect a peripheral nerve end and to separate the nerve from surrounding environment to reduce the development of a symptomatic neuroma.
Summary / comparison of technical characteristics:
The Nerve Capping Device is similar in design and manufacturing, and identical in materials, packaging and sterilization method as its predicate NEUROLAC® (K050573 and K112267).
Table 1 contains a comparison of technological characteristics with the predicate devices:

### Performance Data:
The following performance data were provided in support of the substantial equivalence determination.
## Biocompatibility testing
The biocompatibility evaluation for the Nerve Capping Device was conducted in accordance with the FDA Blue Book Memorandum #G95-1 "Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing," May 1, 1995, and International Standard ISO 10993-1 "Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing Within a Risk Management Process," as recognized by FDA. The Nerve Capping Device is considered a permanent contact device: device contact exceeds 30 days.
The battery of testing included the following tests which were conducted for the predicate NEUROLAC® and leveraged for the Nerve Capping Device, except for cytotoxicity, pyrogenicity and EO residues which were conducted for the Nerve Capping Device.
The predicate test data was leveraged to support the substantial equivalence of the subject device as the device material is exactly the same for the subject and predicate device NEUROLAC® (bioresorbable copolyester poly(DL-lactide-s-caprolactone), and the shape is tubular as the predicate device NEUROLAC® but with one closed end. The Nerve Capping Device is manufactured with an identical production process (with the only difference being the sealing step of the tip), packaging and sterilization method, and the body contact is identical.

| Cytotoxicity | No biological reactivity (Grade 0)<br>was observed | No cytotoxic potential | | |

| Acute systemic toxicity | Test article did not induce a<br>significantly greater biological<br>reaction than the control | Not considered systemically toxic | | |
| Pyrogenicity | Endotoxins were not detected | Non-pyrogenic | | |
| Hemocompatibility: Hemolysis | 0.0% hemolysis was observed | Non-hemolytic | | |
| Hemocompatibility: Prothrombin<br>Time Assay | No adverse effect on prothrombin<br>coaqulation time | Compatible with blood | | |
| Implantation/local tolerance | Relatively mild foreign body<br>response | Relatively mild foreign body response | | |
| (Bio)degradation | After 16 months very small<br>fragments of material were found | Biodegradable | | |
| (Sub)acute/subchronic toxicity | No toxic responses were<br>observed | No subchronic toxicity | | |
| Genotoxicity | No statistical increase was found<br>in the mutation frequency | Non-mutagenic | | |
| Carcinogenicity | No significant carcinogenic<br>potential | No significant carcinogenic potential | | |

| <i>In vitro</i> degradation | Assessment of physical, chemical and<br>thermal properties of the Nerve<br>Capping Device:<br>pH testing Dimensional testing Weight (dry and wet state) Tensile testing Intrinsic viscosity Glass temperature Degradation products Blue dye leak tests Visual inspections | The <i>in vitro</i> degradation at 37 °C<br>behavior for Nerve Capping Device is<br>comparable to the predicate<br>NEUROLAC®, and the shape integrity<br>will be intact for up 10 weeks to form a<br>barrier and separate the nerve stump<br>from the surrounding environment. The<br>degradation pattern is comparable to<br>that of NEUROLAC®. |
| Usability testing | Usability and specifications of the<br>Nerve Capping Device were assessed<br>by providing samples to the intended<br>end users. Their opinion and<br>experience on the usage of the product<br>was used to evaluate the device as<br>design verification and validation<br>activity to determine whether or not it<br>meets the requirements | The overall result is that the device can<br>be used to cover a nerve end in a fast<br>and easy manner and that the<br>procedure is less invasive then current<br>used techniques. The range of<br>dimensions from 1.5 up to 8.0 mm is<br>sufficient and the flat tube end with<br>fixation hole was found to be<br>convenient to fixate the device into the<br>tissue. |
| Suture retention<br>strength | To determine the force necessary to<br>pull a suture from the device or cause<br>the wall of the device to fail | All samples passed the acceptance<br>criteria and are comparable to<br>NEUROLAC® regarding retention<br>forces. The suture retention of a suture<br>placed in the tip section is higher<br>compared to a suture placed in the<br>tube section. |
| Tip dimensional<br>verification | To verify that the specified dimensions<br>of the tip are met | All samples passed the acceptance<br>criteria. The dimensions of the tip of the<br>device (closed part) are within the<br>tolerances as specified. |
## Conclusion:
The non-clinical data and the device verification and validation demonstrate that the Nerve Capping Device should perform as intended in the specified use conditions. The non-clinical data demonstrate that the Nerve Capping Device is substantially equivalent to the predicate devices.
