1. A system comprising:
- a lead configured to be implanted in a tissue of a patient;
at least one electrode electrically coupled to the lead;
an electrical signal processor electrically coupled to the lead, wherein the electrical signal processor is configured to be implanted in tissue remote from the at least one electrode, the electrical signal processor comprising;
a housing, wherein the housing comprises a header,electrical signal sensing circuitry positioned within the housing, wherein the electrical signal sensing circuitry is configured to acquire electrical signals from the at least one electrode,a rechargeable power source positioned within the housing and configured to supply power to the electrical signal processor,a receive coil positioned within the housing and configured to transcutaneously receive a radio frequency magnetic field configured to recharge the rechargeable power source, andan antenna positioned within the header of the housing and configured to communicate via radio frequency wireless telemetry; and
an external programmer configured to generate the radio frequency magnetic field and transcutaneously transmit the radio frequency magnetic field to the receive coil of the electrical signal processor to recharge the rechargeable power source, wherein the radio frequency magnetic field is defined by a frequency between about 30 KHz and about 300 KHz, and wherein the external programmer is further configured to communicate via the radio frequency wireless telemetry with the electrical signal processor, wherein the radio frequency wireless telemetry uses a frequency between about 402 MHz and about 405 MHz.

Abstract
Improved assemblies, systems, and methods provide an electrical signal processor for acquisition and processing of electric signals from tissue. The electrical signal processor is sized and configured to be implanted in subcutaneous tissue. The electrical signal processor includes an electrically conductive case of a laser welded titanium material. Control circuitry is located within the case, the control circuitry including a rechargeable power source, a receive coil for receiving a first radio frequency wireless telemetry to recharge the power source, and an antenna for receiving a second radio frequency wireless telemetry for communication with the electrical signal processor.
