ABSTRACT:
A stylet-actuated, steroid-eluting, screw-in, endocardial, transvenous bipolar pacing lead. In an embodiment, the lead is provided, with a sharpened helix. Advancing and retraction of the helix is accomplished with a stylet having a flattened, screw-driver tip. Rotation of the stylet imparts rotation to the helix assembly, causing the helix to advance or retract. A segmented tip electrode having a porous coating thereon allows steroid from a monolithic controlled released device housed within the electrode assembly to be eluted at the location of the implant site.
