In accordance with the present disclosure there is provided an angioplasty catheter system and method for using such angioplasty catheter system that facilitates controllably delivering focalized pressure to complex lesions. The angioplasty catheter comprises an elongated member having a proximal end, a distal end, and at least one lumen extending at least partially through the elongated member, and an inflatable member proximally affixed to the elongated member adjacent to the distal end and in fluid communication with the at least one lumen, the inflatable member having a radius R and including at least two lobes (), the at least two lobes separated from each other by one or more waist portion () defined by two legs () and a waist portion length () such that upon pressurization, radial stress around the waist portion is directed away from the vessel wall and focalized into the lesion at an angle about perpendicular to the legs () of the upper and lower base of the waist portion () creating variable directional forces from to () to (') resulting in the preferential formation of lesion fractures at the waist of the inflatable member.

Angioplasty balloon catheter for treating vascular disease

The current document is directed to length-adjustable catheters and methods that employ length-adjustable catheters to treat malformations, constrictions, obstructions, lesions, and blockages within patients' blood vessels. The length of the shaft of a length-adjustable catheter, to which the current application is directed, can be adjusted over a range of lengths prior to and during medical procedures. In many implementations, length adjustment is accompanied by indications, to the medical provider, of the extent of a length adjustment. The indications may include one or more of visual markings, haptic feedback, radio-opaque markings, and/or other types of indications. In many implementations, the variable-length mechanism of the length-adjustable catheter is mechanically lockable following length adjustment.

Length-adjustable catheter and method that employs a length-adjustable catheter to treat vascular pathologies

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.

Length and diameter adjustable balloon catheter

The present invention relates to a catheter comprising an outer tube; an inner tube; and a balloon fixed at its proximal sleeve to the outer tube and at its distal sleeve to the inner tube, wherein the inner tube comprises an elastic segment.
