Abstract
A medical catheter comprising an outer tubular member and an inner tubular member slidably disposed within a lumen of the outer tubular member. The inner tubular member includes ridges which project outwardly from the outside surface thereof and which extend longitudinally along substantially the entire length of the inner tubular member to thereby provide a catheter which is flexible and highly resistant to kinking. The catheter further includes connectors for coupling the catheter to a source of fluid and for providing a passageway for a guidewire.
