Intended Use

The Akro-Vu Videoscopic Carpal Tunnel Release System (VCTR) is for use in patients diagnosed with carpal tunnel syndrome that is not associated with, or secondary to, any other known pathology (i.e. idiopathic carpal tunnel syndrome). Preoperative x-rays of the wrist, including a carpal tunnel view, are recommended to aid in the diagnosis of associated pathology (i.e. calcific tendonitis, fracture of the hook of the hamate). This device is indicated solely for releasing the flexor retinaculum (transverse carpal ligament).

Device Story

Akro-Vu VCTRS is a battery-powered, stand-alone videoscopic surgical platform for carpal tunnel release. System includes a reusable video monitor, sterile enclosure, handle with cable assembly, and single-use disposable video-blades. Each blade integrates a camera, light source, and deployable cutting blade. Used by trained physicians in a surgical setting to perform minimally invasive release of the transverse carpal ligament. The physician views the internal wrist anatomy via the monitor to guide the blade deployment and cutting process. The device provides direct visualization of the surgical site, facilitating precise ligament release while minimizing tissue trauma. Benefits include reduced invasiveness compared to traditional open surgery.

Clinical Evidence

No clinical data. Evidence consists of bench testing including microbial barrier effectiveness, blade sharpness comparative analysis, visualization testing, battery capacity, temperature testing (distal end), blade actuation cyclic testing, cut force testing, and mechanical strength testing (torsional, cantilever forces). Cadaveric evaluations were performed to confirm cut force on tissue.

Technological Characteristics

Battery-powered videoscopic system. Materials: Stainless Steel, Ultem, Parylene, Polycarbonate, Cyclo Olefin Polymer, Silicone Rubber. Components: Reusable video monitor, autoclavable handle, single-use disposable video-blades with integrated camera and light source. Sterilization: Autoclavable components. Connectivity: Stand-alone platform.

Indications for Use

Indicated for patients with idiopathic carpal tunnel syndrome requiring release of the flexor retinaculum (transverse carpal ligament). Contraindicated in patients with wrist abnormalities, including distal radial deformities, rheumatoid arthritis, or synovitis.

Regulatory Classification

Identification

#### Predicate Device:

Microaire CTRS / 3M Inside Job - K912871

#### Description of the Device:

The AKRO-VU Videoscopic Carpal Tunnel Release System (VCTRS) is designed as a stand-alone platform to address less invasive surgical approaches for Carpal Tunnel Release procedures performed by trained physicians. The AKRO-VU VCTRS is comprised of a reusable Video-Monitor with Li lon Battery and Charger, an autoclavable Sterile Enclosure with Base Stand to house the Video-Monitor within the sterile field, an autoclavable Handle with cable assembly and Locking Ring, and two styles of single use disposable Video-Blades each containing a camera, light source and deployable blade. The AKRO-VU VCTRS is designed to be a battery powered system.

#### Intended Use:

The Akro-Vu Videoscopic Carpal Tunnel Release System (VCTR) is for use in patients diagnosed with carpal tunnel syndrome that is not associated with, or secondary to, any

other known pathology (i.e. idiopathic carpal tunnel syndrome). Preoperative x-rays of the wrist, including a carpal tunnel view, are recommended to aid in the diagnosis of associated pathology (i.e. calcific tendonitis, fracture of the hook of the hamate). This device is indicated solely for releasing the flexor retinaculum (transverse carpal ligament).

## Contraindications

The device is not intended for use in patients with known abnormalities of their wrist (carpal tunnel), including distal radial deformities, rheumatoid and other synovitis.

## Technological Characteristics:

The Akro-Vu Videoscopic Carpal Tunnel Release System has the following similarities to the Microaire CTRS manufactured and distributed by Microaire pursuant to K912871:

- . The same indications for use and intended use
- The same basic general shape of the working instrument .
- Utilize the same materials for the blade and the housing of the working . instrument
- . Use the same operating principals

## Biocompatibility:

The materials selected for the Akro-Vu Videoscopic Carpal Tunnel Release System have a long history of safe use in the orthopedic industry. The materials include Stainless Steel, Ultem, Parylene, Polycarbonate, and Cyclo Olefin Polymer, and Silicone Rubber.

## Summarv:

The following safety and performance tests were performed in support of the submission:

- · An assessment of the microbial barrier of the Sterile Enclosure was performed to evaluate the effectiveness of the barrier. The enclosure was found to be an effective microbial barrier.
- · A comparative analysis of the blade (subject vs. predicate) was made to evaluate the edge radius for sharpness. The results indicate that both blades were comparable. Visualization testing was performed to test the video imaging capabilities of the system. The target image displayed was focused, illuminated and discernable within the specified ranges.
- · A battery capacity test was performed to determine how long a fully charged battery would power the system. The system power on time exceeded the capacity requirement by a safety factor of 11.
- · Temperature testing was done to determine the temperature at the distal end of the Videoblade at full power after 30 minutes of use. The temperature of the Videoblades tested after 30 minutes of use did not rise more than 1°C.
- A blade actuation test was performed to confirm the blade actuated after repeated actuations against a force. After cyclic testing, all test samples actuated smoothly throughout the entire range and the blade returned to a position sub-flush to the edge of the housing.

{2}------------------------------------------------

- Cut force testing was performed to confirm the cutting force of the Videoblade . was within specified limits. The results indicated that the blades cut the test media within the required force parameters. Cadaveric evaluations of the blade were also performed to evaluate cut force on tissue. The blade was found to provide the necessary cut force on cadaver tissue.
- · A series of strength tests were done to evaluate the Videoblade's ability to withstand typical loads during use. The test results concluded that all test samples met the stiffness and strength specifications for torsional, posterior cantilever, and lateral cantilever forces.

### Conclusion:

Based on the performance testing and the comparative analyses, we believe the subject device performs as intended and is substantially equivalent to the predicate device. Therefore, we conclude that the subject device is safe and at least as effective as the predicate device.
