ABSTRACT:
A first catheter surrounds a guidewire, with the first catheter and guidewire each having a distal portion emplaced in the cardiovascular system of a patient. By this invention, the first catheter may be removed without displacing the guidewire. To accomplish this, one may advance an exchange catheter into the patient to a desired position where the exchange catheter completely surrounds the guidewire distal end and, in turn, is surrounded along part of its length by the first catheter. One causes a proximal end portion of the guidewire to project outwardly through a longitudinal slit of the exchange catheter, so that the proximal end of the guidewire may be grasped. By this means the guidewire may be retained in the desired position as the exchange catheter is advanced into its position within the first catheter and surrounding the guidewire. One then withdraws the first catheter from the patient, while causing the exchange catheter to be held relatively stationary. Thus the guidewire within the exchange catheter is also retained in relatively stationary position without the need for retention of the guidewire by manual grasping. Also, the guidewire may be replaced through the exchange catheter.
