Abstract
A catheter comprising an elongated shaft having a distal shaft section with a first portion having co-axially disposed lumens, and a second portion having laterally off-set, adjacent lumens. The adjacent-lumen portion of the distal shaft section is preferably disposed proximal to the co-axial lumen portion, and comprises a first tubular member secured to a second tubular member such that the longitudinal axis of the first tubular member is laterally off-set from the longitudinal axis of the second tubular member. The coaxial lumen portion extends distally from the distal end of the adjacent-lumen portion, and generally comprises an inner tubular member disposed within an outer tubular member. One embodiment of the invention is a balloon catheter having an inflatable dilatation balloon on a distal end thereof.
