Indications for Use

ISSDE is indicated for use with InterX Transcutaneous Electrical Nerve Stimulator, previously cleared by FDA (K042912). The ISSDE provides the conductive interface between the InterX stimulation device and the patient's skin. The ISSDE is not made with natural rubber latex, is reusable (single patient only), and is provided packaged and labeled as a sterile device, for single patient use. As a sterile device, the ISSDE can be applied to patients in a sterile post-operative healthcare setting. NRG only guarantees sterility for the first application, however, ISSDE can be repositioned and reapplied (single patient only) as a non-sterile device for subsequent applications. Refer to the labeling for reuse instructions.

Device Story

ISSDE is a flexible, sterile laminate electrode designed to interface with the InterX Transcutaneous Electrical Nerve Stimulator. It consists of a top cover, reinforcement film, dual conductive members with printed silver, biocompatible conductive hydrogel, and a 2-conductor cable. The device is applied to the patient's skin to deliver electrical stimulation. It is intended for single-patient, multiple-application use; provided sterile for the first application in post-operative settings and can be repositioned for subsequent applications. The electrode does not contain active electronics, software, or firmware. It facilitates the transmission of electrical signals from the stimulator to the patient, potentially aiding in pain management or therapeutic stimulation as determined by the clinician using the InterX system.

Clinical Evidence

Bench testing only. Performance evaluation included impedance testing at 1000 Hz, energy distribution uniformity, and biocompatibility (cytotoxicity, delayed-type hypersensitivity, and primary skin irritation per ISO 10993). Sterilization validation was performed per ANSI/AAMI/ISO 11137. Results confirmed impedance and energy distribution are substantially equivalent to predicate devices.

Technological Characteristics

Flexible laminate electrode; materials include white polyethylene foam top cover, silver-printed conductive members, biocompatible hydrogel, and 24 AWG tinned copper 2-conductor cable. Connectivity via touch-proof keyed connector. Sterilization via gamma radiation. No active electronics, software, or firmware.

Indications for Use

Indicated for use with InterX Transcutaneous Electrical Nerve Stimulator as a conductive interface between the device and patient skin. For single-patient use; latex-free; provided sterile for initial application in post-operative settings.

Regulatory Classification

Identification

A cutaneous electrode is an electrode that is applied directly to a patient's skin either to record physiological signals (e.g., the electroencephalogram) or to apply electrical stimulation.

(Classic # 2404) (K900519) The electrode is composed of a top cover, a reinforcement film, dual conductive members with printed silver, biocompatible conductive hydrogel, a release liner which protects the hydrogel before use and during storage and a 2-conductor cable secured between the reinforcement film and the conductive members. # Bench Testing: The InterX Sterile Self-Adhesive Dual Electrode (ISSDE) and the predicate devices were tested per protocol in accordance with the FDA's "Draft Guidance for Industry and Staff: Class II Special Controls Guidance Document: Cutaneous Electrode (April 5, 2010)". ISSDE gel electrodes were sterilized to a very high radiation level (greater than 40 kGy) to create a worst case scenario for gel degradation. Electrical performance of the ISSDE was tested for uniform energy distribution along the length of each electrode. Comparison of energy distribution of the ISSDE electrodes were made to FDA cleared predicate gel electrode devices. Another performance factor of particular interest was impedance, which was measured across the total surface area of each ISSDE gel electrode. The results from the tests performed provide evidence that design verification per 21CFR-820.30(g) was met. ISSDE complies with the applicable requirements of the following standards: | No. | Standard Reference & Revision | Title | Deviations | |-----|-------------------------------|---------------------------------------------------------------------|------------| | 1 | ISO 15223-1(Second Edition) | Medical Devices – Symbols to be<br>used with medical device labels, | None | {2}------------------------------------------------ | | | labeling, and information to be | | |---|----------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------| | | | supplied - Part 1: General | | | | | requirements | | | 2 | ISO 10993-1:1997 | Biological evaluation of medical<br>devices - Part 1: Evaluation &<br>Testing | None | | 3 | ISO 10993-5:1999 | Biological evaluation of medical<br>devices - Part 5: Tests for In Vitro<br>Cytotoxicity | None | | 4 | ISO 10993-10:1996 | Biological evaluation of medical<br>devices - Part 10: Tests for Irritation<br>and Delayed-type Hypersensitivity | None | | 5 | ISO 11607-1:2006 (R) 2010 | Packaging for terminally sterilized<br>medical device- Part 1:<br>Requirements for materials, sterile<br>barrier systems and packaging<br>systems | None | | 6 | ANSI/AAMI/ISO 11137-1:2006/(R)<br>2010 | Sterilization of health care products<br>- Radiation -Part 1: Requirements<br>for development, validation, and<br>routine control of a sterilization<br>process for medical devices | None | | 7 | ANSI/AAMI/ISO 11137-2:2012 | Sterilization of health care products<br>- Radiation -Part 2: Establishing the<br>sterilization dose | None | Guidance Document: The recommendations of the FDA's "Draft Guidance for Industry and Staff: Class II Special Controls Guidance Document: Cutaneous Electrode (April 5, 2010)" were taken into account in preparing this 510(k) submission. ### Performance Data: Design validation of the ISSDE was confirmed and documented. Tests to measure impedance and variation of energy distribution, which determine safety and efficacy, were conducted to compare the ISSDE to three predicate devices. Values of current were calculated from testing each electrode. Impedance values were tabulated for all gel electrodes using samples per electrode type. Impedance values for the ISSDE are confirmed to be substantially equivalent to predicate devices Variation of energy distribution was also determined to be substantially equivalent, which confirms avoidance of hot spots. The results of the impedance and variation of energy distribution tests conducted confirm that the ISSDE design is substantially equivalent to three FDA cleared predicate devices. Performance data for the Proposed ISSDE is compared to that of the predicate devices mentioned above. Results from the biocompatibility study, physical and functional performance evaluation demonstrate that the Proposed ISSDE is substantially equivalent to the legally marketed devices. {3}------------------------------------------------ ______________________________________________________________________________________________________________________________________________________________________________ # Substantial Equivalence Table: : : ה : : | Substantial<br>Equivalence<br>Item | InterX Sterile<br>Self-Adhesive<br>Dual Electrode<br>(ISSDE)<br>(New Device) | Predicate<br>Device 1 | Predicate<br>Device 2 | Predicate<br>Device 3 | |-------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Sterile | YES | NO | YES | NO | | Intended Use | Sterile, post-operative,<br>reusable, self-adhesive,<br>stimulating electrode (single<br>patient) | Non-sterile, reusable, self-<br>adhesive, stimulating<br>electrode (single patient) | Sterile, post-operative, self-<br>adhesive, stimulating<br>electrode (single patient) | Non-sterile, reusable, self-<br>adhesive, stimulating and<br>recording electrode<br>(single patient) | | Indications for<br>Use | ISSDE is<br>indicated for use<br>with InterX<br>Transcutaneous<br>Electrical Nerve<br>Stimulator.
