Abstract
A catheter and guidewire exchange system in which the guideware is contained within a guidewire leumen in the indwelling portion of the catheter and with the guidewire and catheter being separated externally of the patient. The catheter includes a guidewire lumen which is slit longitudinally along the length of the catheter. The guide member is carried by the catheter and serves to spread the slit of the lumen to guide the guidewire into or out of the slit guidewire lumen. The guide member may be advanced along the catheter and guidewire in zipper-like fashion so that the proximal ends of the guidewire and catheter will be separated while the distal portions will be merged.
