STIMULATION WITH UTILIZATION OF CASE ELECTRODE
First Claim
1. A method for delivering electrical stimulation therapy to a patient, the method comprising:
- delivering electrical stimulation current with a first polarity via a first electrode carried by a housing of an implantable medical device (IMD);
delivering electrical stimulation current with the first polarity via a second electrode of the IMD substantially simultaneously with the electrical stimulation current delivered via the first electrode, wherein the second electrode is carried by a lead coupled to the IMD; and
delivering, via a third electrode of the IMD, electrical stimulation current with a second polarity opposite the first polarity delivered via the first electrode and the second electrode.

Abstract
This disclosure describes techniques that support delivering electrical stimulation via an electrode on a housing of an implantable medical device (IMD) while substantially simultaneously delivering electrical stimulation via one or more electrodes, having the same polarity as the electrode on the housing, on one or more leads engaged to the IMD. The stimulation may be constant current-based or constant voltage-based stimulation in the form of pulses or continuous waveforms. Delivery of stimulation via both a housing anode and one or more lead anodes, for example, may allow a user to control current paths between the housing electrode and the lead electrode(s) in a relative manner to achieve different electric or stimulation field shapes.
