Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.
