First Claim
Patent Images
1. A method of stimulating at least one location in the heart of a patient, comprising:
- selecting at least one location in the heart;
selecting an ultrasound source configured to transmit at least one ultrasound pulse to said at least one location, said at least one ultrasound pulse configured to create a propagating action potential in cardiac tissue;
aiming said ultrasound source at said at least one location; and
transmitting said at least one ultrasound pulse to said at least one location, said transmitting causing said action potential at said at least one location such that said action potential propagates.

Abstract
An ultrasound cardiac stimulation system comprising:
- a spatially selective ultrasound source comprising at least one ultrasound transducer located outside the circulatory system; and
- a controller;
- where the controller generates an electrical response in the heart by directing the ultrasound source to transmit a high enough power level of ultrasound to one or more locations in the heart.
