MEANS TO SECURELY FIXATE PACING LEADS AND/OR SENSORS IN VESSELS
First Claim
1. A method for non-destructive anchoring of a cardiac lead member to a coronary vessel, the method comprising:
- passing a first guide wire into the coronary vessel;
deploying the stent structure over the first guide wire and into the coronary vessel, the stent structure having a second guide wire attached at a target site;
expanding the stent structure to engage an inner surface of the coronary vessel;
deploying a lead member over the second guide wire to the target site, the lead member comprising an anchor structure; and
attaching the anchor structure to the stent structure.

Abstract
According to embodiments of the present invention, a cardiac lead system adapted for fixation to a vessel including an expandable fixation mechanism adapted to engage an inner surface of the vessel and a lead member comprising an anchor structure at distal end, the anchor structure configured to removably engage with fixation mechanism. Such anchor structure may be helical, and may removably engage fixation mechanism upon rotation or an application of torque, and may be extendable and/or retractable. Fixation mechanism may be polymer coated weave and/or mesh to trap anchor structure. Lead member and/or fixation mechanism may include electrodes and/or sensors, and lead member may include L-shape, S-shape, spiral, and/or sinusoidal shape for positioning of electrodes and/or sensors or for facilitated engagement of anchor structure. A guide wire attached to fixation mechanism during deployment may, prior to detachment, serve to guide lead member to a target site at fixation mechanism.
