Abstract
A guide catheter and medical lead are provided wherein the lead may be used as a pull wire to steer the guide catheter. The guide catheter is provided with a flexible distal segment and the lead is provided with a distal engaging member, which may also serve as an electrode. The distal engaging member interacts with the distal catheter end such that traction applied to the proximal lead end causes flexion of the distal segment of the catheter to advance the flexible distal segment between a non-flexed position and a flexed position, allowing the catheter to be steered around obstacles.
