Implantable medical device with electrodes on multiple housing surfaces
First Claim
1. An implantable medical device comprising:
- a housing that includes a first surface and a second surface;
a plurality of electrodes, wherein a first set of the electrodes is located on a first surface of the housing, and a second set of the electrodes is located on a second surface of the housing; and
a stimulation generator within the housing configured to deliver electrical stimulation to a patient via the first and second sets of the electrodes.

Abstract
An implantable medical device (IMD) with a housing and electrodes on at least two surfaces of the housing is described. The surfaces may be, for example, opposed, substantially parallel surfaces, e.g., top and bottom surfaces. Location of electrodes on multiple surfaces of the housing may allow the IMD to deliver stimulation to a variety of tissues and with a variety of current field configurations. For example, the IMD may deliver peripheral nerve field stimulation (PNFS) to one or more tissue areas via electrodes selected from one or both of the surfaces to, for example, reduce the sensation of pain in a tissue area proximate to an implantation site of the IMD without targeting a specific nerve. The IMD may be implanted between or within intra-dermal, deep dermal, or subcutaneous layers of the tissue of the patient to deliver PNFS to any one or more of these layers.
