Abstract
A collar for anchoring a lead in a vein. The collar includes a body member having axial ends and a throughbore extending between the axial ends. The throughbore is sized for receiving at least a portion of the lead. The body member includes one or more grooves disposed along its outer surface for receiving a suture for anchoring the lead. At least a portion of the inner surface of the body member includes structure sized and positioned to project into the throughbore for generating a tangential compression against the lead, thereby inhibiting slippage of the lead when the lead is received in the throughbore.
