Patent ID: 7499757

Claim:
A myocardial lead attachment system for securing a distal end of a lead within a myocardium of a patient's heart, the system comprising: an anchor mechanism configured formed of a bioabsorbable or biodegradable polymer, the anchor mechanism configured to advance through myocardial tissue in a first orientation and configured to anchor against an epicardial surface in a second orientation; a tether having a proximal end and a distal end, wherein the anchor mechanism is coupled to the distal end of the tether; and a lead body having a proximal end, a distal end, a surface feature formed on a portion of the lead body for promoting formation of scar tissue around the portion, and a lumen extending through the lead body, wherein the lead body and the lumen are 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 mechanism during implantation; wherein the anchor mechanism and the tether are configured to couple to the lead body, thereby chronically retaining the distal end of the lead body in the heart after implantation.
