Device inputs include user-selected frequency and intensity via buttons and dials. It transforms electrical energy into biphasic pulses (spike with exponential decay) delivered through self-adhesive electrodes. Output is displayed on an LCD. Used by patients in home settings for pain management and muscle conditioning. Healthcare providers do not operate the device; patients use it to manage pain or improve muscle performance. Benefits include non-pharmacological pain relief and muscle conditioning. Device includes timer, output jacks, and charging jack. ## Clinical Evidence Bench testing only. No clinical data provided. Performance verified through software validation and compliance with IEC 60601-1, IEC 60601-1-11, and IEC 60601-2-10 standards. ## Technological Characteristics Portable, battery-operated (7.2V Ni-MH) electrical stimulator. ABS plastic housing. Two-channel output with galvanic isolation. Biphasic waveform (spike with exponential decay). Frequency range 1-70 Hz. Pulse width 5 ms @ 1k ohms. Maximum output voltage 100V @ 10k ohms. Includes LCD display, timer, and intensity controls. Software-controlled via microprocessor. ## Regulatory Identification A transcutaneous electrical nerve stimulator for pain relief is a device used to apply an electrical current to electrodes on a patient's skin to treat pain. ## Predicate Devices - MPP ([K131910](/device/K131910.md)) - H4 ([K112485](/device/K112485.md)) - H4 ([K103738](/device/K103738.md)) - Pain Buddy ([K102051](/device/K102051.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

IEC 60601-1-11 (2015): Medical electrical equipment – Part 1-11: General Requirements for basic safety and essential performance - Collateral standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment. IEC 60601-2-10 (2012)/Amendment 1 2001, Medical electrical equipment - Part 2-10: Particular requirements for the safety of nerve and muscle stimulators. Conclusions from non-clinical performance data After performing non-clinical performance studies, the data shows that the HBOTC is substantially equivalent to the predicates as a powered muscle stimulator and transcutaneous electrical nerve stimulator for pain relief. --- **Source:** [https://fda.innolitics.com/submissions/NE/subpart-f%E2%80%94neurological-therapeutic-devices/NUH/K160255](https://fda.innolitics.com/submissions/NE/subpart-f%E2%80%94neurological-therapeutic-devices/NUH/K160255) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
