1. An anchor for a medical device lead, the anchor comprising:
a flexure finger portion having a plurality of flexure finger members forming an anchor lumen configured for insertion of a lead body therein;
a radial bulkhead portion having a radial bulkhead with a flexure profile configured to operatively engage the plurality of flexure finger members and induce flexure of the flexure finger members and encourage radial compressive forces to be imparted upon the lead body inserted in the anchor lumen when the radial bulkhead portion is disposed in an engaged position with respect to the flexure finger portion, wherein the flexure profile is configured to provide a constant tactile feedback to a clinician during movement of the plurality of flexure finger members from a disengaged position through an engaged position; and
a locking mechanism configured to retain the flexure finger portion and the radial bulkhead portion in relative positions to maintain the flexure of the flexure finger members in the engaged position.
