1. A medical lead, comprising:
- an elongate body having an electrical conductor therein;
a first retaining segment, extending along a length of the body, forming a first fixed portion of an outer surface of the body and including a first end and a first plurality of projections extending in a first direction from the first portion of the outer surface, each of the first plurality of projections including a terminal edge directed toward the first end; and
a second retaining segment, longitudinally separate and detached from the first retaining segment, extending along another length of the body, forming a second fixed portion of the outer surface of the body and including a second end opposite the first end, and a second plurality of projections extending in a second direction opposite the first direction from the second fixed portion of the outer surface, each of the second plurality of projections including a terminal edge directed toward the second end;
wherein the first plurality of projections and the second plurality of projections are formed from a bioabsorbable material and are adapted to interfere with a wall of a vessel to retain the body within the vessel.
