Abstract
Apparatus and method are disclosed for facilitating balloon catheter exchange in the vascular system of a patient. The apparatus and method concern means for holding a guidewire longitudinally fixed with respect to a guiding catheter while a balloon catheter is moved over the guidewire. Specifically, the guidewire is held longitudinally fixed with respect to the guiding catheter by way of magnetic coupling. A first magnetic element constitutes a portion of the guide wire or is attached to the guide wire to move with it. A second magnetic element is located proximate the balloon catheter but is not fixed to the balloon catheter. When the guidewire is moved within the guiding catheter to a location at which the first magnetic element reaches its point of closest approach to the second magnetic element, magnetic force holds the guidewire against movement relative to the guiding catheter even while a balloon catheter is being moved over the guidewire.
