Abstract
Chronic pain management can be achieved by electrically anesthetizing a peripheral nerve with on-demand electrical nerve block (OD-ENB). OD-ENB can be provided by an implantable capsule. Externally, at least a portion of the capsule can be constructed of a conductive membrane and the rest of the capsule comprises a biocompatible material. A blocking electrode contact, a return electrode contact, and a powering/communication component can be within the capsule. The blocking electrode contact can deliver a direct current (DC) through a portion of the conductive membrane to block conduction in the neural tissue to provide the OD-ENB. The return electrode contact can receive a return current from the neural tissue through another portion of the conductive membrane. The powering/communication component can communicate with one or more external components located external to the patient's body to receive a power signal. Notably the capsule has no internal battery.
