Patent ID: 8050775

Claim:
An implantable medical lead for transmitting electrical signals between cardiac tissue and an implantable pulse generator, the lead comprising: a lead body having a proximal end and an open distal end, and including a pre-formed biased portion between the proximal and distal ends, the pre-formed biased portion adapted to fixate the lead against an interior wall of a coronary vessel upon implantation and including a three-dimensional bias and a two-dimensional bias; a connector located at the proximal end of the lead body configured for coupling the lead assembly to an implantable pulse generator; an electrode on the lead body; a conductor coil coupled to the electrode extending within the lead body from the proximal end toward the distal end; and an open lumen extending longitudinally through the distal end of the lead body such that the lead can be threaded over a guidewire during implantation of the lead.
