Zenith Technical Innovations (ZTI) Therm-X machines combine cold, heat, contrast, compression, and DVT prophylaxis for patient treatment. The machines are designed for rehabilitation, sport medicine, and home settings. ZTI came to Embedded Bytes to fix firmware issues and add new features. Embedded Bytes worked with ZTI's current hardware contractor to address hardware improvements. We also worked with ZTI's medical device consultant company for FDA documentation and compliance.
