1. A stimulation system, comprising:
- a control device configured for transmitting acoustic waves through body tissue; and
an implantable stimulator including a casing, one or more acoustic transducers disposed within the casing and configured for transforming the acoustic waves into electrical current, a stimulator electrode disposed within the casing and configured for electrically stimulating adjacent body tissue, a sensor disposed within the casing and configured for sensing one or more parameters within the body, and a control unit disposed within the casing and operable to control the delivery of electrical stimulation energy to the stimulator electrode based at least in part on one or more stimulation parameters and the one or more parameters sensed by the sensor, wherein the electrical stimulation energy is directly transformed from the electrical current.

Abstract
An implantable stimulation system comprises an implantable stimulator and a control device. The control device is configured to transmit acoustic waves to the implantable stimulator, and the implantable stimulator is configured to transform the acoustic waves into electrical current, and generate stimulation energy based on the electrical current. For example, the electrical current can be transformed into electrical energy that can be used to generate the stimulation energy. Or the electrical current can contain signals used to directly or indirectly control the generation of the stimulation energy.
