Tests compared cutting efficacy, mucosal lift size, and thermal damage against predicate devices. Additional testing included knife operation, dimensional verification, durability, shelf-life (ASTM F1980-16), sterilization (ISO 11135:2014), biocompatibility (ISO 10993), and electromagnetic/electrical safety.

Technological Characteristics

Endoscopic electrosurgical knife with integrated saline irrigation channel. Materials validated per ISO 10993. Sterilization via ethylene oxide (ISO 11135). Electrical safety per AAMI/ANSI ES60601-1, IEC 60601-2-2, and IEC 60601-2-18. Shelf-life validated per ASTM F1980-16. Device is a standalone accessory for use with external electrosurgical generators and endoscopes.

Indications for Use

Indicated for patients requiring endoscopic mucosal lesion lifting and tissue cutting within the digestive tract via high-frequency electrosurgery.

### <Test A>

A test to evaluate the performance to cut the digestive tract mucosa and compare the result with that of the predicate device. The subject device and the primary predicate device 1 (KD-620LR, K092309) were compared for the equivalency in cutting the ex-vivo porcine digestive tract mucosa (esophagus, stomach, and colon).

### <Test B>

A test to evaluate the lifting of the digestive tract mucosa and compare the size of mucosal lift with that of the predicate device. The subject device and the predicate device 3 (Hybridknife, K083608) were compared for the equivalency in lifting of the ex-vivo porcine digestive tract mucosa (esophagus, stomach, and colon).

### <Test C>

A test composed of the test items "cut the mucosa" and "lift the mucosa by induction of saline to the submucosal layer" to compare the degree of thermal damage on the ex-vivo porcine digestive tract (esophagus, stomach, and colon) wall caused by the subject device and that caused by the predicate device 3 (Hybridknife, K083608). The histological study was carried out to evaluate the degree of thermal damage.

<Other performance testing>

- > Knife operation with the compatible endoscopes
- >> Dimension of each part of the knife
- > General durability
- Risk analysis was carried out in accordance with established in-house acceptance criteria based on ISO 14971:2007. The design verification tests and their acceptance criteria were identified and performed as a result of this risk analysis assessment.
- Shelf-life testing was conducted based on an accelerated aging test in accordance with ASTM F1980-16, the standard guide for accelerated aging of sterile barrier systems for medical devices. Three-year aging test will be performed to demonstrate longer stability and support the results of the accelerated aging test.
- Sterilization validation was carried out with Methods Half-cycle approach in accordance with ISO 11135:2014.
- Biocompatibility testing was performed in accordance with the FDA Guidance, Use of International Standard ISO-10993, 'Biological Evaluation of Medical Devices Part 1: Evaluation and Testing within a risk management process' issued on June 16, 2016.
- Electromagnetic compatibility, electric safety, and thermal safety had been confirmed.
