Abstract:
A method of forming a tip on a catheter having an elongate shaft, the method comprising the steps of:providing an elongate shaft having an outer surface, a distal portion, and a lumen extending longitudinally therethrough;providing a first tubular member having an inner surface, an outer surface, and a distal end;providing a second tubular member having a proximal end, and an outer surface;providing a third tubular member having an inner surface;positioning the first tubular member so that it overlays the distal portion of the elongate shaft such that the inner surface of the first tubular member is proximate the outer surface of the elongate shaft;positioning the second tubular member so that the proximal end of the second tubular member is proximate the distal end of the first tubular member and a lumen of the second tubular member is in axial alignment with the lumen of the elongate shaft;positioning the third tubular member so that it overlays both the first tubular member and the second tubular member such that the inner surface of the third tubular member is proximate the outer surface of the first tubular member and the outer surface of the second tubular member; andfusing the first tubular member, the second tubular member, and the third tubular member to form the catheter tip.
