Myocardial lead with fixation mechanism
First Claim
Patent Images
1. A method of implanting a myocardial lead attachment system, the method comprising:
- delivering an anchor mechanism coupled to a distal end of a tether to an epicardial surface;
threading a lead body having a proximal end, a distal end, a lumen extending through the lead body, and a fixation mechanism positioned at the distal end over a proximal end of the tether;
advancing the lead body and fixation mechanism over the tether toward the anchor and through the myocardium while the fixation mechanism is in a first collapsed configuration; and
deploying the fixation mechanism to a second configuration on the epicardial surface of the heart to retain the lead body at a chosen location.

Abstract
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.
