## Indications for Use

The Skintact® Multifunction Electrodes are for use on adults and children over eight years old for external defibrillation, pacing, monitoring and cardioversion. The device is non-sterile and single-use only.

## Device Story

Skintact Multifunction Electrodes are self-adhesive, single-use, non-sterile disposable electrodes; used for external defibrillation, pacing, monitoring, and cardioversion. Device consists of foam backing, laminated metallic substrate, and conductive adhesive gel (DH 02). Electrodes are applied to patient skin; interface with monophasic and biphasic defibrillators to deliver electrical therapy or acquire ECG signals. Used by clinicians in clinical settings. Benefits include reliable electrical contact for life-saving cardiac interventions. Packaged in pairs with color-coded cabling in aluminized, heat-sealed pouches.

## Clinical Evidence

Bench testing only. Biocompatibility testing performed per ISO 10993. Performance testing conducted per internationally recognized standards for defibrillation electrodes, confirming compliance with specifications for active gel area (min 82 cm²) and total area (min 164 cm²). Accelerated aging studies confirmed 24-month shelf-life.

## Technological Characteristics

Foam backing; laminated metallic substrate; conductive adhesive gel (DH 02). Self-adhesive, single-use, non-sterile. Dimensions meet standard requirements for adult/pediatric (>8 years) defibrillation and pacing. Compatible with monophasic and biphasic defibrillators.

## Regulatory Identification

An automated external defibrillator (AED) system consists of an AED and those accessories necessary for the AED to detect and interpret an electrocardiogram and deliver an electrical shock (e.g., battery, pad electrode, adapter, and hardware key for pediatric use). An AED system analyzes the patient's electrocardiogram, interprets the cardiac rhythm, and automatically delivers an electrical shock (fully automated AED), or advises the user to deliver the shock (semi-automated or shock advisory AED) to treat ventricular fibrillation or pulseless ventricular tachycardia.

## Predicate Devices

- Philips HeartStart Defibrillation Pads (model DP2) ([K955628](/device/K955628.md))

Substantially Equivalent to: The Skintact® Multifunction Electrodes are substantially equivalent to the Philips HeartStart Defibrillation Pads (model DP2). Philips Medical Systems, formerly Heartstream, cleared the HeartStart Defibrillation Pads (model DP2) under K955628, a bundled submission including defibrillator and accessories.

Device Description: Skintact Multifunction Electrodes are self-adhesive, non-sterile, single use disposable clectrodes. Skintact® Multifunction Electrodes consist of a foam backing, a laminated metallic substrate and conductive adhesive gel DH 02. Several shapes and sizes are offered, in accordance with standards. Skintact® Multifunction Electrodes are packaged in pairs with color-coded cabling within watervapor-proof, heat-sealed, non-transparent, aluminized pouches.

Indication for Usc: The Skintact Multifunction Electrodes are for use on adults and children over 8 years for external defibrillation, pacing, monitoring and cardioversion. The device is non-sterile and single use only.

Summary of Comparison and Testing to Demonstrate Equivalence: Biocompatibility tests in accordance with ISO 10993 have been performed on the hydrogel. The testing confirms that the gel is biocompatible and does not introduce any risks. Testing to evaluate the performance of the Skintacte Multifunction Electrodes in accordance with internationally recognized standards demonstrated that the performance of the Skintact Multifunction Electrodes meet specifications and are suitable for use with the monophasic and biphasic defibrillators. Skintact Multifunction Electrodes are packaged in the same packaging used by Leonhard Lang GmbH in many previously approved products with demonstrated 24 month shelf-life. In addition, the Skintact Multifunction Electrodes were tested in accelerated aging. confirming the shelf-life of 24 months for DH02 gel and materials. Skintact Multifunction Electrodes used for adult defibrillation (and children over 8 years) and pacing have a minimum active (gel) area of 82 cm² and the total area of the two electrodes is at least 164 cm2, thus meeting the standard requirements. Other comparisons demonstrated that the Skintact Multifunction Electrodes do not introduce new risks and are substantially equivalent to the legally marketed predicate device.

Dear Ms. Duncan:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
