Safety systems and methods for ensuring safe use of intra-cardiac ultrasound catheters

摘要

A system and method for limiting a temperature induced in a body by an ultrasound imaging catheter are provided. The method includes receiving, at an isolation box, an imaging signal from an imaging catheter, receiving, at an isolation box, a signal indicative of a temperature of tissue adjacent to the imaging catheter, removing power to the imaging catheter at the isolation box if the signal indicates the temperature of tissue adjacent to the imaging catheter exceeds a known value, and sending the imaging signal from the catheter to a processor if the signal indicates the temperature of tissue adjacent to the imaging catheter is less than the limit.
