1. A stimulation system, comprising:
- a control device configured for transmitting acoustic waves through body tissue; and
an implantable stimulator including one or more acoustic transducers configured for transforming the acoustic waves into electrical current, a power unit configured to receive the electrical current directly from the one or more acoustic transducers and to directly transform the electrical current into electrical stimulation energy, and a stimulator electrode configured for electrically stimulating adjacent body tissue using the stimulation energy.

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.
