ABSTRACT:
A rapid exchange type dilatation catheter having a flexible distal portion which has a coil supported inflation lumen which is defined at least in part by an outer tubular member. An inner tubular member is disposed within the distal portion having a guidewire receiving inner lumen which extends proximally from a guidewire port in the distal end of the inner tubular member to a location proximal to an inflatable member on the distal portion of the catheter. The distal end of the relatively high strength proximal portion receives the proximal end of the support coil so as to provide a smooth transition.
