Implantable medical device for providing stimulation therapy
First Claim
1. An implantable medical device, comprising:
- a case;
a circuit board within the case;
a charging coil within the case and positioned on a first side of the circuit board;
a telemetry coil within the case and positioned on a second side of the circuit board, wherein the telemetry coil is positioned on a spacer that maintains a gap between the telemetry coil and the second side of the circuit board; and
a header coupled to the case, wherein the header comprises one or more connector assemblies that are each configured to receive a stimulation lead.

Abstract
An electrical stimulation system provides stimulation therapy to a patient. The system includes a neurostimulation lead that contacts patient tissue and couples with an implantable stimulation device, such as an implantable pulse generator, that receives stimulation parameters for providing stimulation therapy to a patient. The implantable stimulation device includes a header with a plurality of connector assemblies that receive an end of the neurostimulation lead, and a case containing a charging coil and a telemetry coil coupled to programming circuitry on a printed circuit board, which is in turn coupled to the connector assemblies via a feedthrough assembly. The telemetry coil receives data from an external programmer and transmits the data to the programming circuitry, which in turn uses the data to communicate to the connector assemblies and the neurostimulation lead to provide stimulation therapy to a patient.
