Abstract: A burr hole plug comprises a plug base configured for being mounted around a burr hole. The plug base includes an aperture through which an elongated medical device exiting the burr hole may pass. The burr hole plug further comprises a retainer configured for being mounted within the aperture of the plug base. The retainer further includes first and second slidable clamping mechanisms configured for securing the medical devices therebetween within the aperture of the plug base. A method comprises introducing the medical device through the burr hole, mounting a plug base around the burr hole, such that the medical device extends through the plug base aperture, mounting the retainer within the aperture of the plug base, and sliding the first and second clamping mechanisms secure the medical device therebetween.

Abstract: A lead is configured and arranged for brain stimulation. The lead includes a proximal end and a distal end. The proximal end includes a plurality of terminals disposed at the proximal end. The distal end has a non-circular transverse cross-sectional shape and includes a plurality of electrodes disposed at the distal end. A plurality of conductive wires electrically couple at least one of the plurality of electrodes to at least one of the plurality of terminals.

Abstract: Systems for adjusting a position of an implanted medical device within a patient include an engagement tool configured to couple to the implanted medical device. The engagement tool adjusts the position of the medical device when coupled to the implanted medical device. Methods of adjusting a position of an implanted medical device within a patient include locating the implanted medical device, coupling an engagement tool to the medical device, and adjusting a position of the engagement tool to adjust the position of the medical device.

Abstract: A burr hole plug comprises a plug base including a flange configured for being mounted around a burr hole, an aperture through which an elongated medical device may pass, and tabs configured for extending within the cranial burr hole to center the plug base relative to the cranial burr hole. The burr hole plug further comprises a retainer configured for being mounted within the aperture of the plug base to secure the medical device. A method may comprise locating the plug base within a burr hole, such that the tabs are disposed within the burr hole to center the plug base relative to the cranial burr hole, introducing the elongated medical device through the cranial burr hole and into the brain tissue of the patient, mounting the retainer within the aperture of the plug base, and actuating the retainer to secure the medical device.

Abstract: Systems and methods for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to at least treat or prevent obesity and/or other eating disorders, as well as drug, nicotine and alcohol addiction, uses at least one system control unit (SCU) producing electrical pulses delivered via electrodes implanted in the brain and/or producing drug infusion pulses, wherein the stimulating drug(s) are delivered to targeted areas in the brain.

Abstract: Systems and methods for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to at least treat or prevent diabetes uses at least one system control unit (SCU) producing electrical pulses delivered via electrodes implanted in the brain and/or producing drug infusion pulses, wherein the stimulating drug(s) are delivered to targeted areas in the brain.

Abstract: A stimulation system is described that includes an implantable microstimulator. A tail may be coupled to a distal end of the implantable microstimulator. In one embodiment, the stimulation system includes an implantation tool that includes an insertion cannula, a handle, a bushing, and a detachable blunt dissector tip. The bushing is situated within the insertion cannula and may position the implantable microstimulator longitudinally within the insertion cannula when the implantable microstimulator is placed within the insertion cannula. The detachable blunt dissector tip may be attached to the tail of the implantable microstimulator. The stimulation system may further comprise an end cap that includes an upper portion and a base portion conformable over at least a portion of curved tissue. An open trough extends through the base upper portions and may be configured to guide the implantation tool through the tissue at various angles.
