Abstract:
1. A method for delivering a biologically stimulating electrical output, said method comprising: implanting in tissue an isotropic receiver-stimulator having an acoustic transducer assembly; coupling an acoustic energy source to the patient; directing acoustic energy from the acoustic energy source to the isotropic receiver-stimulator, wherein the acoustic energy that intersects the isotropic receiver-stimulator is transferred into the transducer assembly in a manner that is substantially insensitive to the relative orientation of the receiver-stimulator to the acoustic energy source, wherein the acoustic energy is converted by the transducer assembly into electrical signals; wherein the electrical signals are demodulated by the receiver-stimulator to produce a biologically stimulating electrical output; and wherein the biologically stimulating electrical output is delivered to the tissue by the receiver-stimulator.
