Patent ID: 7499759

Claim:
A myocardial lead attachment system for securing a lead within the myocardium, the system comprising: an anchor configured to advance in a first orientation, rotate to a second orientation, and anchor against an epicardial surface in the second orientation, wherein the anchor is configured to be generally parallel to the epicardial surface in the second orientation; a tether coupled to the anchor, the tether having a proximal end and a distal end; a lead body having: a proximal end and a distal end, and a lumen for accepting the tether configured such that the lead body can be threaded over the proximal end of the tether and slideably advanced over the tether toward the anchor during implantation; wherein the tether extends out the distal end of the lead body; a distal lock for engaging the tether to the distal end of the lead body, the distal lock comprising: a lock structure formed on a distal end of the tether, and a lock housing in the lumen, wherein the lock structure mates with the lock housing and restrains motion of the lead body with respect to the tether in either of a proximal or a distal direction; and a proximal lock restraining longitudinal motion of the tether with respect to the lead body.
