#### IV. DEVICE DESCRIPTION

The joimax® Electrosurgical Instruments are comprised of a series of instruments to facilitate the delivery of electrical energy from an RF generator to the patient tissue for use in cutting and/or coagulation of tissue.

The joimax® Electrosurgical Instruments use Radio Frequency (RF) energy to induce thermal effects on tissue. The radio frequency is generated by high oscillating electrical current received from a commercially available RF generator.

The joimax® Probes are available in both monopolar and bipolar probe configurations. All joimax® Probes are designed for specific use with joimax® Handpieces. The joimax Handpieces can be used with compatible commercially available surgical generators.

#### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

Electrosurgical instruments, by nature, are instruments intended to deliver electrical energy directly to tissue to facilitate tissue cutting/coagulation in surgical applications.

{6}------------------------------------------------

The primary predicate devices (Aaron Reusable Electrosurgical Electrode, K014201; Bi Polar TRIGGER-Flex Electrode, K003126) and reference predicates (Arthrex Opes Electrodes and Accessories, K023986; Meddusa BiPolar System, K130110) were used to demonstrate substantial equivalence.

At a high level, the subject and predicate devices are based on the following same technological elements:

- All devices use electrical energy to generate high-frequency (RF) energy as a means to cut and/or coagulate tissue
- . All instrument sets are comprised of a cutting tool (e.g. electrode), an ergonomic user interface (e.g. handpiece) and a connector (e.g. cable) to the generator
- The joimax® monopolar electrode, the Aaron and Arthrex Opes monopolar . electrode predicates are all ball tipped.
- The ball diameter of the joimax® monopolar electrode (2.5 mm) is within I the diameters (2 mm-5 mm) of the predicate device. The tip diameter (2.0 mm) for the joimax® bipolar electrodes is well within the established diameters of the predicate device (1-3 mm).
- . The joimax® bipolar electrode shaft diameters (2.0 mm, 2.75 mm) are also within the established diameters of the predicate device (1-3 mm).
- The joimax® instruments shaft lengths (250-320 mm) are within the shaft . length range of the predicate device (monopolar: 130-343 mm, bipolar 180-400 mm).
- The ioimax® handpieces come in two configurations, namely a pencil ■ design and a handled design. These designs are consistent with the handpiece designs of the predicate device which also come in pencil or handled configurations.
- The connecting cable length of the joimax® electrosurgical instruments is . 3.5 meters, which is similar to the predicate Aaron device cable length and the Trigger-Flex cable length of approximately 3 meters.
- The joimax® handpieces and the predicate Arthrex Opes handpieces are I provided non-sterile and are intended to be sterilized by the user.

#### VII. PERFORMANCE DATA

# Biocompatibility Testing

The biocompatibility evaluation for the Brand X 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 battery of

{7}------------------------------------------------

testing included the following tests:

- Cytotoxicity ●
- Irritation
- Sensitization
- Acute Systemic Toxicity ●

The joimax electrosurgical instruments are considered direct tissue contacting for < 24 hours.

### Sterilization/Shelf-Life

The bipolar instruments were validated to achieve a sterility assurance level of 10 6 using ISO 11137-1/-2 (bipolar instruments). The disposable monopolar instruments were adopted into a validated EO cycle following AAMI TIR 28:2009. The reusable instruments moist heat sterilization cycle was validated per ISO 17665-1. Packaging validation was performed to ensure the devices provided sterile maintain their sterile barrier integrity following the requirements outlined in ISO 11607-1.

# Electrical Safety and Electromagnetic Compatibility (EMC)

Electrical safety and EMC testing were conducted on the joimax® electrosurgical instruments. The instruments comply with the IEC 60601-1 standard for safety and the IEC 60601-1-2 standard for EMC.

# Performance Testing

Performance testing was conducted for the joimax® Electrosurgical Instruments to demonstrate the suitability of the device for its intended use. The results of the testing indicate that the joimax® Electrosurgical Instruments is substantially equivalent to the predicate devices and is safe and effective for its intended use.

Dimensional and Physical Properties Verification was performed to demonstrate the instruments met their specifications and confirmed the physical properties of the devices. Ex-vivo testing was conducted using multiple types of soft animal tissue (kidney, liver and muscle tissue). Testing included all ranges of relevant parameters, such as power settings, activation duration, and waveforms / frequencies. Effect on tissue was assessed and determined to be highly comparable to the predicate device.

The joimax® Electrosurgical Instruments met all specified criteria and did not raise new safety or performance questions. Based on the design verification performance the joimax® Electrosurgical Instruments was found to have a safety and effectiveness profile that is similar to the predicate device.
