1. (a) Identification. A thermal system for insomnia is a prescription device for use in patients with insomnia that is used to apply a specified temperature to the skin surface.

2. (b) Classification. Class II (special controls). The special controls for this device are:

   1. (1) The patient-contacting components of the device must be demonstrated to be biocompatible.
   2. (2) Performance testing must demonstrate electromagnetic compatibility and electrical safety.

   3. (3) Non-clinical performance testing must demonstrate that the device performs as intended under anticipated conditions of use. The following performance characteristics must be evaluated:

      1. (i) Thermal performance of the device, including maintenance of the target temperature, must be evaluated under simulated use conditions.
      2. (ii) Mechanical testing to demonstrate the device can withstand forces under anticipated use conditions.
      3. (iii) Mechanical testing to demonstrate the device is resistant to leakage under anticipated use conditions.
   4. (4) Software verification, validation, and hazard analysis must be performed.
   5. (5) Patient labeling must be provided to convey information regarding safe use of the device, including instructions for assembly.
