Research work on heart anomalies is currently done using four-electrode catheter systems inserted into the subject’s left ventricle, but those devices are far too large to be used on tiny test subjects. Telemetric implants, on the other hand, create a much more useful measuring environment and could contain all sensor electronics, power, and data transmission electronics. Researchers at the University of Western Ontario are using 3D printing to create prototypes small enough to be used on even the tiniest subjects like mice.

Below is a look at prototypes of this device:
