Abstract
A body implantable lead for placement in a selected coronary vein includes a resilient retention structure for inhibiting displacement of the lead because of heart beat action, breathing or other body movement. The retention structure includes a plurality of resilient projections that are attached to the lead body and which are adapted to project at a predetermined acute angle to the axis of the lead body when unconstrained. Prior to being routed through the vascular system, the projections can be bonded to the lead body to provide a low profile with a biodegradable adhesive. Following exposure to body fluids, the adhesive dissolves, releasing the projections so that they can engage the walls of the vein in which the lead is disposed.
