ABSTRACT:
A lead or catheter for implantation in a body for conducting electrical current between an electrical device and a location in the body, including an elongate tubular insulating material, a first portion of electrically conductive braid forming a closely fitting sheath around a portion of the insulating material, an electrical coupling means for coupling the device to the lead and an electrically insulated connection means for electrically connecting the braid and the coupling means. A part of the electrically conductive braid is exposed for providing the electrical energy to the body. Preferably the electrically insulated connection means includes an integral portion of the braid surrounded by a tubular insulating member. The lead may be configured as an endocardial catheter, or may be used elsewhere in the body and have one or more fingers, each with a respective exposed portion of braid.
