Abstract

The present technology is generally directed to implantable medical device systems configured to provide cardiac resynchronization therapy. In some embodiments, the implantable medical device system comprises a housing, electrodes carried by the housing, a transducer configured to produce input voltage signals in response to ultrasound energy, and a circuit configured to provide, via an electrical pathway, output voltage signals based on the input voltage signals. The circuit comprises a movable switch, and a slew rate detector configured to detect whether a voltage rate of an individual pulse of the input voltage signals exceeds a predetermined threshold voltage rate. The circuit is configured to move the switch to an open position in response to the detected voltage rate exceeding the predetermined threshold voltage rate.

First claim

I/We claim:

1 . An implantable medical device system, comprising:
a housing; electrodes carried by the housing; a transducer within the housing and configured to produce input voltage signals in response to receiving ultrasound energy; and a circuit electrically coupled to the transducer and within the housing, wherein the circuit is further electrically coupled to the electrodes, and wherein the circuit is configured to
receive the input voltage signals;
detect whether a voltage rate of an individual pulse of the input voltage signals exceeds a predetermined threshold rate; and
when the detected voltage rate exceeds the predetermined threshold rate, prevent the corresponding pulse of the input voltage signals from being delivered to the electrodes.
