Device User interfaces with device to set time and temperature for Note 1: application; LCD Controller Screen shows temperature and time setting, power, and fault detection.

The biocompatibility tests performed on the predicate devices, and their Note 2: results, are not in the public domain. UL testing, however, was performed, to test successfully function, performance, safety and durability.

{7}------------------------------------------------

### Therasage Heating Pad 510(K) Submission

Note 3 Any differences in appearance or structure between the subject device and the predicate devices do not raise new questions of safety and effectiveness.

- Note 4
In order to obtain premarket approval, the predicate devices were required to successfully pass the then applicable electrical safety standards. The subject device has similarly satisfied the most current safety standards recognized today.

### Performance Data

In all instances, the Therasage Heating Pad functioned as intended and passed all manufacturing tests, including tests for functionability, performance, safety, and durability. These tests included routine evaluations during manufacturing and conformance to established standards. The results of these nonclinical tests which reflect substantial equivalence with the performance of the two cited predicate devices arrse from testing for:

Relative Emissivity and Energy Density Flammability Electromagnetic Compatibility Product Risk Evaluation General Electrical Safety

In sum, the information from all of these tests and evaluations indicates without exception that the technology of the subject device and the predicate devices is substantially equivalent. Any technological, aesthetic, or ancillary differences between the Therasage Heating Pad and the predicate devices do not raise any questions of safety or effectiveness.

### Substantial Equivalence

The subject device, as well as the indications for use and the technology upon which the device operates, is outlined above. It is a device that is substantially similar to at least two predicate devices. Such substantial equivalence presents the subject device as being as safe and effective as the predicate devices. The Therasage Heating Pad has the same intended uses and similar indications as the predicate devices. The technological differences, if any, between the Therasage Heating Pad and the predicate devices are insubstantial and are aesthetic differences, at best. No discerned technological differences exist that raise, suggest, or implicate any new questions of safety and effectiveness.
