Abstract
Steerable low profile dilatation catheter having a flexible elongate tubular member with proximal and distal extremities and with a flow passage extending therethrough. An adapter is secured to the proximal extremity of the tubular member. A separate balloon having proximal and distal extremities is provided. The balloon has its proximal extremity mounted on the distal extremity of the flexible elongate tubular member. A core wire extends through the flow passage of the tubular member and through the balloon and beyond the distal extremity of the balloon. A tip coil is provided which is formed of a radiopaque material and has proximal and distal extremities. The proximal extremity of the tip coil is secured to the distal extremity of the balloon. The distal extremity of the core wire extends into the tip coil but is spaced from the distal extremity of the tip coil.
