Description

ABSTRACT:
An intravascular catheter having a relatively long proximal shaft portion, a relatively short distal shaft section and a flexible intermediate shaft which allows the articulation of the distal and proximal shaft sections. The intermediate shaft section has a guidewire port in fluid communication with a guidewire receiving inner lumen which extends through the catheter shaft. In one presently preferred embodiment the portion of the intermediate shaft section through which the guidewire lumen extends is formed by a helical coil having an expanded portion which defines the guidewire port. The catheter allows both rapid exchange and over-the-wire modes of operation.
