IMPLANTABLE NEUROLOGICAL LEAD WITH LOW POLORIZATION ELECTRODE

摘要

An implantable neurological lead (40) having at least one low polarization electrode (42) carried on the distal end (41) of the lead (40). The implantable neurological lead (40) is coupleable to an implantable neurological stimulator or implantable neurological monitor. In exemplary embodiments, the low polarization electrode (42) provides (a) delivery of a constant current pulse (85) having a current leading edge (86) and a current trailing edge (87) that are substantially the same, or (b) sensing of a physiological signal substantially immediately after delivering a stimulation pulse through electrode (42) without substantial distortion. Systems and methods of using or making the lead (40) are also disclosed.
