Abstract

A wireless implantable pressure sensing system has been developed for short term urological studies. In in vitro testing, it was able to sense a physiologically relevant pressure range (0-1.5 psi gauge) with a resolution of 0.02 psi. In vivo testing demonstrated its ability to operate for >90 hours while implanted in a porcine model. Possible urination events and peristalsis were measured. The design of a second generation of this device is also presented.
