Abstract
Abstract A lead comprising both a main lead and a transverse lead. The main lead includes a main lead body with a longitudinal axis and at least one electrode. The Transverse lead includes a transverse lead body and at least one electrode, where the transverse lead body extends laterally from the main lead body and curves around the longitudinal axis of the main lead body to partially encircle at least a portion of the main lead. In one embodiment, the transverse lead is adapted to press the at least one electrode on the transverse lead against endocardial tissue. At least a portion of the main lead and at least a portion of the transverse lead are both adapted to be housed within and pass through an implant catheter. In an alternative embodiment, there is a lead system which comprises a first lead and a second lead, where the second lead includes a sleeve, where the first lead is adapted to move through the sleeve to attach the first lead to the second lead.
