ABSTRACT:
Intracardiac lead for compliant fixation of a distal end of the lead to cardiac tissue. A fixation helix is disposed at the distal end of the lead. The fixation helix has a first end rigidly attached to the compliant fixation device and a second end that is sharpened to facilitate insertion of the fixation helix into cardiac tissue. The fixation helix can be designed to provide for either electrically active or inactive fixation. Once the lead is implanted in the cardiac tissue, the compliant fixation device, connecting the lead with the fixation helix, reduces the amount of lead movement that is transferred to the patient's tissue at the site of implantation of the fixation helix and reduces those forces from lead movement that could cause dislodgment of the fixation helix. The compliant fixation device thereby decreases the amount of irritation to the cardiac tissue, lessens the possibility of fibrous tissue growth around the area of the fixation helix, decreases the chance of dislodgment of the fixation helix, and reduces the possibility of perforation of the cardiac wall or tamponade of the pericardial sac.
