Abstract: Adjustable balloon catheter including an inner tubular member that has an inflation lumen defined therein. An expandable member is coupled to the distal end portion of the inner tubular member and has an inner chamber in fluid communication with the inflation lumen. The expandable member is transitionable between a deflated configuration and an inflated configuration. The expandable member defines has a non-cylindrical shape along at least a portion of a working length thereof when in the inflated configuration. An outer tubular member is movable relative to the inner tubular member, the outer tubular member includes a distal end. The outer tubular member is moveable between an extended position disposed over the expandable member and a retracted position proximal to the extended position. The outer tubular member is selectively positioned between the extended position and the retracted position to define an exposed length of the working length of the expandable member.

Abstract: Adjustable catheter including an elongate tubular shaft having a proximal portion, a distal portion, and a length therebetween. The elongate tubular shaft has a guidewire lumen defined therein extending along at least the distal portion of elongate tubular member and further has at least one pressure lumen defined therein extending along at least a section of the length of the elongate tubular shaft. The at least one pressure lumen having a proximal end and a closed distal end. A fluid adaptor is in fluid communication with the at least one pressure lumen. The catheter has a stiffness profile and a flexibility profile along a length there of and at least one of the stiffness profile and the flexibility profile selectively adjustable upon introduction of a pressurizing fluid into the at least one pressure lumen.
