Patent ID: 8175724

Claim:
A method for implanting a cardiac lead device in a body lumen comprising: initially implanting an outer guide into the body lumen, the outer guide having a proximal end and a distal end and including a tubular wall defining a lumen extending between the proximal and distal ends; guiding an inner guide through the outer guide; guiding the cardiac lead device into the body lumen through the inner guide, the device including a conductive lead body having a proximal end and a distal end, the lead body defining at least one lead lumen extending between the proximal and distal ends, the lead body including a tubular wall; and deploying an expandable fixation mechanism from a compressed position to an expanded position such that the fixation mechanism engages an internal wall of the body lumen with the lead body extending through the expandable fixation mechanism, the fixation mechanism being secured to an outer surface of the tubular wall of the lead body to provide selective relative movement between the fixation mechanism and the lead body; and moving the lead body relative to the expanded fixation mechanism.
