LENGTH AND DIAMETER ADJUSTABLE BALLOON CATHETER

摘要

Adjustable balloon catheter (100) including an inner tubular member (110) that has an inflation lumen (130) defined therein. An expandable member (140) 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 (120) 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.
