| 20090112327 | BURR HOLE PLUG DESIGNS - 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. | 04-30-2009 |
| 20090149917 | MULTIMODAL NEUROSTIMULATION SYSTEMS AND METHODS - A system for performing a neurostimulation trial comprises an external trial stimulator capable of delivering stimulation energy to a plurality of electrodes carried by one or more stimulation leads. The external trial stimulator is configurable to operate in a plurality of stimulation energy delivery modes to respectively emulate one of different neurostimulator types. The system may further comprise a programmer capable of configuring the external trial stimulator to operate in one of the stimulation energy delivery modes. The programmer may be capable of generating a first programming screen capable of allowing a first set of stimulation parameters to be defined for the first neurostimulator type, and a second programming screen capable of allowing a second set of stimulation parameters to be defined for a second neurostimulator type. | 06-11-2009 |
| 20100145357 | BURR HOLE PLUG HAVING DUAL SLIDABLE CLAMPING MECHANISMS - 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. | 06-10-2010 |
| 20110125223 | NEUROSTIMULATION SYSTEM AND METHOD FOR COMPOUNDING CURRENT TO MINIMIZE CURRENT SOURCES - A neurostimulation system and method of providing therapy to a patient implanted with a plurality of electrodes using a plurality of electrical sources is provided. A source-electrode coupling configuration is determined from the electrical sources and electrodes. Electrical current is respectively conveyed between active ones of the plurality of electrical sources and active subsets of the plurality of electrodes in accordance with the determined source-electrode coupling configuration. The total number of the electrodes in the active electrode subsets is greater than the total number of the active electrical sources. | 05-26-2011 |
| 20110125224 | NEUROSTIMULATION SYSTEM AND METHOD FOR COMBINING CURRENT USING RECONFIGURABLE CURRENT SOURCES - A neurostimulation system and method of providing therapy to a patient implanted with a plurality of electrodes using a plurality of electrical sources is provided. One of the electrical sources is reconfigured from a second polarity to a first polarity. A first electrical current is generated with the one electrical source when configured in the first polarity. A second electrical current is generated with another one of the electrical sources. At least a portion of the first electrical current and at least a portion of the second electrical current is combined in one of an additive manner and a subtractive manner to produce a first combined electrical current. The first combined electrical current is conveyed to or from one or more of the electrodes. | 05-26-2011 |
| 20110137372 | METHODS AND APPARATUS FOR USING SENSORS WITH A DEEP BRAIN STIMULATION SYSTEM - A system and method for applying stimulation to a target stimulation site within a patient, while avoiding undesirable eye movement side effects of the stimulation, are provided. The method includes determining whether eye movement, sensed by internal or external electrodes, is a side effect of a conveyed electrical stimulus. If the eye movement is a side effect, the electrical current distribution of the stimulus is modified in order to steer a locus of the electrical stimulus from one tissue region of the patient to another different tissue region of the patient, thereby mitigating the eye movement side effects. For example, the locus of the electrical stimulus may be steered away from the oculomotor nerve. Eye movement side effects of DBS treatment may include apraxia of lid opening, downward movement and adduction of only one eyeball, and/or continuous deviation of both eyeballs. | 06-09-2011 |
| 20110160797 | METHODS TO CONCURRENTLY STIMULATE DIFFERENT BRAIN TARGETS - A method for treating a patient having a dysfunction using a stimulation lead within the brain of a patient is provided. The stimulation lead carries a plurality of electrodes adjacent to a plurality of brain regions. Pulsed electrical waveforms having different sets of stimulation parameters are generated and then concurrently delivered to the plurality of electrodes, thereby concurrently stimulating the plurality of brain regions to treat the dysfunction. | 06-30-2011 |
