Claim:
A rapid exchange catheter comprising: an elongated shaft having a proximal end and a distal end, the elongated shaft including: a hypotube having a proximal end and a distal end; a midshaft portion having a proximal end and a distal end, the midshaft portion being attached near its proximal end to a location near the distal end of the hypotube, the midshaft portion including a braided member; and a distal portion including an inner tubular member and an outer tubular member surrounding the inner tubular member, a short guidewire lumen being defined by the inner tubular member and an inflation lumen being defined between the inner tubular member and the outer tubular member, the distal portion being attached to the midshaft portion and extending distally therefrom; wherein the midshaft portion includes a flared portion and a tab prior to being attached to the distal portion such that when the midshaft portion and the distal portion are attached at an attachment location, a first portion of the braided member is disposed radially exterior to an outer surface of the outer tubular member, and the tab including a second portion of the braided member is disposed between the inner tubular member and the outer tubular member; a balloon disposed near the distal end of the elongated shaft; and a core wire attached to the hypotube and extending distally of the distal end of the hypotube and across the location at which the proximal end of the midshaft portion is attached to the distal end of the hypotube.
