摘要： A medical lead having a lead body and a biocompatible cuff and especially suitable for use as a nerve electrode. In the preferred bipolar embodiment the lead body has two conductors running therethrough. The distal end is coupled to a pulse generator, the proximal end is coupled to the biocompatible cuff. The biocompatible cuff is cylindrical and is constructed from collagen. Preferably the collagen is multi-layer, i.e. the first portion is cross-linked to an amount greater than the second portion. Through such a construction the collagen promotes tissue ingrowth in the region proximate a nerve and does not permit tissue ingrowth in the region away from the nerve, e.g. the exterior of the cuff.

摘要： A bipolar, plasma-generating electrosurgical apparatus and system wherein the return electrode is enclosed within an electrosurgical shaft, and the active electrode is located on the outside surface of the shaft such that in treating the tissue, the tissue is exposed to plasma generated on the active electrode, but is minimally exposed to electric fields generated between the active and return electrodes. Due to the configuration of the electrodes, electric fields generated between the electrodes are directed away from the target tissue and inwardly towards the return electrode within the shaft, thereby electrical stimulation of neuromuscular structures in the tissue by the electric fields is minimized.
