摘要:
Systems for treating a patient with a medical condition include a lead having an array of electrode contacts each being programmable to have either a first polarity or a second polarity and a programming device configured to test a multiplicity of different electrode contact polarity configurations in which a programmed polarity of one or more of the electrode contacts is varied. Methods of using an implantable stimulator system include implanting a lead having an array of programmable electrode contacts disposed thereon in communication with a stimulation site, testing a multiplicity of different electrode contact polarity configurations in which a programmed polarity of one or more of the electrode contacts is varied, selecting an optimal electrode contact polarity configuration out of the multiplicity of different electrode contact polarity configurations, and applying the stimulation current via the optimal electrode contact polarity configuration to the stimulation site in accordance with one or more stimulation parameters.

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.

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.

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.
