Abstract:
1. An implantable microstimulator, comprising: a microstimulator housing comprising an exterior surface with a metal region, the housing defining an exterior and an interior; a plurality of thin, flat, conductive electrodes each having an exposed broad active surface that is disposed over the metal region of the exterior surface of the housing; non-conductive adhesive sandwiched between, and in direct contact with, the metal region and each of the plurality of conductive electrodes, the non-conductive adhesive attaching each of the plurality of conductive electrodes to a portion of the metal region with the non-conductive adhesive disposed on top of the exterior surface of the housing and beneath the exposed surface of each of the plurality of conductive electrodes; an electronic subassembly disposed in the interior of the housing; at least one conductive via extending from the interior of the housing to a location that is exterior to the housing, the at least one conductive via electrically coupled to the electronic subassembly; and at least one exterior conductor that is disposed entirely external to the housing, the at least one exterior conductor electrically coupling the conductive via to the plurality of conductive electrodes, wherein at least a portion of the at least one exterior conductor is disposed external to the adhesive; wherein the plurality of conductive electrodes are configured and arranged to stimulate tissue adjacent to the plurality of conductive electrodes on the housing of the microstimulator when implanted.
