A myocardial lead attachment system for securing a distal end of a lead within a myocardium of a patient's heart. The system includes a lead body, an anchor mechanism formed of a bioabsorbable or biodegradable polymer for engaging a surface of the patient's heart and a surface feature formed on a portion of the lead body for promoting formation of scar tissue around said portion of the lead body.

Absorbable myocardial lead fixation system

The present invention is a myocardial lead attachment system for securing a lead within the myocardium. The attachment system includes an anchor configured to engage the heart, a tether coupled to the anchor and a lead body. The lead body has a proximal end, a distal end, a lumen for accepting the tether and a lock housing in the lumen. A lock structure is on the tether and mates with the lock housing and restrains motion of the lead with respect to the tether in either of a proximal or a distal direction.

Distal or proximal fixation of over-the-tether myocardial leads

The present invention is a myocardial lead attachment system and method for securing a distal end of a lead within the myocardium of a patient's heart. The system includes an anchor, a tether coupled at a distal end to the anchor and a lead body. The lead body has a proximal end, a distal end, and a lumen extending therethrough for receiving the tether. A fixation mechanism is at the distal end of the lead body, and is adapted to collapse to a first configuration during implantation and deploy to a second configuration after implantation.
