An intravascular catheter device includes an expandable portion secured to a flexible catheter tube. The expandable portion is slidable relative to a sheath to selectively expose a plurality of struts for outward bowing movement and compression within said sheath. An incising element associated with one of the struts is configured to incise atherosclerotic material when the intravascular catheter device is placed within a blood vessel, the struts are exposed for outward bowing movement, and the expandable portion is retracted along the blood vessel.

An adjustable loop ring stripper for stretching an arterial wall outwardly as plaque is excavated inwardly.

An apparatus and method for the treatment of intravascular medical conditions is provided. The device comprising a handle assembly, an expandable portion defined by a plurality of struts oriented along a longitudinal axis and a tip member affixed to a distal end of the struts. The struts are moveable between a collapsed and an expanded position. A catheter tube extends from the handle assembly to the expandable portion. An elongate member is disposed within the catheter tube and is in communication with the handle assembly and the tip member.

A medical device is disclosed for cutting an object in a body lumen, including: a rotatable drive shaft; and a rotatable rotation structure which is connected to the drive shaft, the rotation structure including: a proximal portion; a distal portion; and a constricted portion provided between the proximal portion and the distal portion, the constricted portion including: a first tapered portion which includes a first cutting portion and decreases in diameter toward the distal side; a second tapered portion which includes a second cutting portion and decreases in diameter toward the proximal side; and a bottom portion which is provided between the first tapered portion and the second tapered portion.

Systems and methods for treating cellulite including an apparatus that applies or a method involving disrupting, stretching, re-orienting or tearing septa to eliminate or reduce the appearance of cellulite. In one approach, an expandable member is placed between tissue layers to stretch or tear septa connecting tissue layers between which fat deposits are contained.

A catheter used for percutaneous endovascular procedures is described. The catheter is configured to be used for engagement and treatment of obstructive lesions in a patient's vasculature. The catheter includes a tube having a leading edge that is configured to score or cut a lesion in a vasculature. The tube may be an expandable outer tube, and placed around an inflatable inner tube, such that inflation of the inner tube expands the outer tube. Expansion of the inner tube may connect or laterally lock the inner tube to the outer tube, allowing both tubes to move in unison through the vasculature. The leading edge can score or cut lesions as it moves in the vasculature.

A platform device for material excision or removal from vascular structures for either handheld or stereotactic table or robotics platform use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions or follow a central lumen of another device or over a wire in a longitudinal direction. Flush and vacuum tissue transport mechanisms may be incorporated as well as single or multiple arrays of image guidance elements, directional elements, ablation elements and other interventional assistance elements. A single tube or an inner sheath and an outer sheath which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks or scoopulas and provisions for simultaneous or differential beak or scoopula closing under their differential rotation may be incorporated.

An intravascular device is provided having a flexible catheter tube with an expandable portion located on an end thereof. The expandable portion has a plurality of struts capable of being moved between an expanded and a collapsed position. An incising element provided along at least a portion of one of the struts has a sharpened edge for creating an incision in atherosclerotic material located within a blood vessel and generating microparticles of the same when the expandable portion is in the expanded position.
