For symptomatic relief and management of chronic pain and as an adjunctive treatment in the management of post-surgical and post-traumatic acute pain.
Device Story
Spectrum II, Spectrum Plus, and Spectrum MAX-SD are Transcutaneous Electrical Nerve Stimulation (TENS) devices. These devices deliver electrical impulses through electrodes placed on the skin to provide pain relief. Used in clinical or home settings, they are operated by patients or healthcare providers to manage chronic pain or post-surgical/post-traumatic acute pain. The device functions by modulating nerve signals to alleviate pain symptoms, serving as an adjunctive therapy. Output is controlled by the user to adjust stimulation parameters for comfort and efficacy.
Clinical Evidence
No clinical data provided; substantial equivalence is based on the established nature of TENS technology for pain management.
Technological Characteristics
TENS device; electrical stimulation output; portable form factor; intended for symptomatic pain relief.
Indications for Use
Indicated for symptomatic relief and management of chronic pain, and as adjunctive treatment for post-surgical and post-traumatic acute pain in patients.
Regulatory Classification
Identification

Dear Mr. Bouchard:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
