Abstract: A lead assembly and associated process include a lead and an integrated feature that facilitates extraction of the lead from the associated body passage. The integrated feature in one embodiment is a sheath received between the associated body passage and received over the lead. The sheath has a first portion extending from adjacent the proximal end to adjacent the distal end of the lead, where the first portion has an inner surface facing with the lead outer surface and the first portion having an outer surface facing radially outward from the lead outer surface. A second portion of the sheath extends from adjacent the distal end to adjacent the proximal end of the lead. The second portion has an inner surface received over the outer surface of the first portion, and the second portion further having an outer surface abutting an inner surface of the associated body passage that receives the lead therein. The integrated feature is alternatively a wire, band, or spoke assembly.
