ABSTRACT:
The invention is directed to a catheter formed at least in part of a multilayered member having a first layer which is fusion bondable to another catheter component such as the skirt of an inflatable balloon and a second layer which is adjacent the first layer having a melting point greater than the first layer so that the multilayered member of the catheter is not deformed when the other catheter component is fusion bonded to the first layer of the multilayered member. The second layer is preferably lubricious in nature. In one embodiment of the invention, the multilayered member is a tubular element with the lubricious second layer defining an inner lumen extending within the tubular element. The outer layer of the tubular member may extend beyond the distal end of the inner layer and form a non-traumatic distal tip. Alternatively, a flexible non-traumatic distal tip may be fusion bonded to at least the outer layer of the multilayered tubular member.
