ABSTRACT:
A dilation catheter having a shaft divided into a proximal portion and a distal portion. A dilation balloon is attached to the distal portion of the shaft. The proximal portion of the catheter may have a coating or a sleeve applied thereto to stiffen the proximal portion of the shaft. Alternatively, a dual lumen tube forms the proximal portion of the shaft while two separate tubes form the distal portion of the shaft thus making the distal portion more flexible then the proximal portion of the shaft.
