A medical lead having a lead body 3 and a biocompatible cuff 20 and especially suitable for use as a nerve electrode. In the preferred bipolar embodiment the lead body has two conductors 11,12 running therethrough. The distal end is coupled to a pulse generator 6, 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 40 is cross-linked to an amount greater than the second portion 42. 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. <IMAGE> |
