• Applicant: Neurovision Medical Products, Inc.
• Product Code: ETN · Ear, Nose, Throat
• Decision Date: Apr 8, 2011
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 874.1820
• Device Class: Class 2

Intended Use

The Paired Hydrogel Electrode is used for evoked electrophysiological monitoring in soft tissue surgeries were motor nerves are at risk.

Device Story

The Paired Hydrogel Electrode is a surface electrode designed for EMG monitoring during surgery. It consists of two 'Comfort Gel A' discs conjoined at a single DIN plug, effectively shorting the electrodes to provide a single pole of electrophysiological monitoring. This configuration allows for coverage of surface areas too wide for a single electrode. The device is used in clinical surgical settings, operated by healthcare professionals, and connects to standard EMG monitoring units. By facilitating the detection of motor nerve activity, the electrode assists surgeons in identifying and avoiding nerves at risk during soft tissue procedures, potentially reducing the risk of nerve damage.

Clinical Evidence

Bench testing only. Performance testing demonstrated equivalence in electrode adhesion, impedance, and electrophysiological properties compared to the predicate singlet electrode. Biocompatibility testing was conducted per ISO 10993 (Irritation) and the Agarose Overlay Method (Cytotoxicity). Shelf-life testing was performed according to ANSI/AAMI EC12:2000, demonstrating a 3-year shelf life.

Technological Characteristics

Surface electrode consisting of two 'Comfort Gel A' discs conjoined at a single DIN plug. Non-sterile. 3-year shelf life. Compatible with standard EMG units. Biocompatible materials tested for sensitization, cytotoxicity, and irritation.

Indications for Use

Indicated for patients undergoing soft tissue surgeries where motor nerves are at risk, requiring evoked electrophysiological monitoring.

Regulatory Classification

Identification

#### Date of Summary:

#### Device Identification:

Trade or Proprietary Name: Paired Hydrogel Electrode (final name TBD) Common or Usual Name: Hydrogel Surface Electrode Classification Name: Surgical nerve stimulator/locator Device Class: Class II Classification: 8874.1820 ETN Product Code:

#### Predicate Devices

- The Paired Hydrogel Electrodes are substantially equivalent to the following predicate devices currently distributed commercially in the U.S .:
- . M203KEN; Neonatal ECG Electrode (K092744), referred to in this document as the Singlet Hydrogel (K092744)
- 3M Pediatric "Red Dot" hydrogel electrode accessory RLN Systems Nerve Locator/Monitor; . Model A (K902080), superseded by,
- . Neurovision (SE: Surface Electrode) Nerve Locator/Monitor (K954601)

#### Device Description

The Paired Hydrogel Electrodes are a modification of the M203KEN electrode currently distributed as the Singlet and Triplet Hydrogel Electrodes by Neurovision Medical Products. The Paired Hydrogel Electrode is created by attaching two Singlet M203KEN electrodes by their lead wires to the same DIN plug (shorting the electrodes). The Paired version is designed to provide a single pole of electrophysiological monitoring across a surface too wide to be covered by a single electrode.

#### Indication for Use

The Paired Hydroget Electrode is used for evoked electrophysiological monitoring in soft tissue surgeries were motor nerves are at risk.
