Abstract

An implantable endocardial (10) lead with retractable sharpened helix (34). The piston (36) has a central bore (42) for re-ceiving a specialized stylet (44). The stylet comprises a flexible wire (56) having an enlarged distal end or tip (60). An elastomeric sliding tube (58) fits over the wire. When the proximal end of the stylet is inserted into the bore in the piston, the wire can be with-drawn slightly, pulling the enlarged tip into the tube, and wedging the tube against the walls of the bore. By manipulating the sty-let, the helix can be exposed outside of the lead, or retractable into the lead, as desired.
