Medical Implant Test System - TableTop (MITS-TT)

The MITS-TableTop (MITS-TT) is a compact and easy-to-use radiofrequency (RF) induced field generator optimized for scaling and validating transfer function models (deposited power, heating or terminal voltage) of active implantable medical devices (AIMD) inside low and high permittivity media.

Medical Implant Test System – TableTop (MITS-TT).

It operates at 64 MHz and 128 MHz, and is fully compliant with all relevant test specifications (ISO 10974, ASTM F2182, PC76, and FDA guidance).

Validation is possible with minimal remounting of the AIMD by adjusting phase and amplitude between the two electrode pairs, thereby varying the induced field following the Test Field Diversity method. The test system only requires low power (~43 dBm) and will be shipped calibrated.

MITS-TT comprises two units (high and low permittivity media). The two pairs of orthogonal electrodes are integrated in the phantom. The dual-band source, amplifiers and control computer are integrated in a small rack.
