Abstract
The invention relates to a catheter and guidewire exchange system in which the guidewire is contained within an indwelling portion of the catheter and with the guidewire and the catheter being separated externally of the patient. The catheter includes a guidewire lumen and a longitudinal slit which penetrates through the catheter wall and into the guidewire lumen. The catheter walls adjacent the slit are provided with reinforced edges which function to maintain the slit in a normally closed position during the catheterization procedure, when desired.
