A catheter system for treating lesions is provided. The system is suitable for treatment of bifurcation lesions, has a low profile and provides substantially predictable translational and rotational positioning. In one embodiment, the system includes a fixed wire balloon catheter and a partially attached guidewire lumen, wherein the guidewire lumen is attached to the catheter at a crotch point. The location of the crotch point is predetermined so as to provide substantially predictable positioning. Several embodiments of the system are described for various types of lesions and vessel configurations.

Vessel treatment devices

A device for introduction into a body vessel includes a main elongated element, a balloon positioned at the main elongated element distal end, a distal connecting element positioned at the distal end of the balloon to receive a guidewire during use, and a longitudinally movable sheath positioned external to the main elongated element, a position of the sheath distal end with respect to the balloon defining an exposed portion of the balloon that expands when fluid is delivered to the balloon through the inflation lumen.

Systems and methods for treating a vessel using focused force

There is provided a microcatheter having a proximal solution lumen and a distal tip portion with a guidewire lumen. The microcatheter and methods of use thereof allows for introduction of solution into a vessel while manipulating the guidewire and/or the microcatheter itself. The solution may be a contrast solution, for viewing of the vessel, a therapeutic or diagnostic solution, or any other type of solution.

Microcatheter with distal tip portion and proximal solution lumen

A device for positioning a catheter at an ostium. The device includes an attachment mechanism for direct attachment to the catheter at a location proximal to a treatment device positioned on the catheter, the attachment mechanism having a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end. The device also including a stopper element extending from the distal end of the attachment mechanism and projecting away from the longitudinal axis, the stopper element being bendable in a direction toward the proximal end of the attachment mechanism.

Positioning device for ostial lesions

A system and method for treating a vessel is provided. A catheter system includes an inner elongated element and an outer elongated element positioned coaxially with respect to the inner elongated element. A proximal occlusion element is positioned at and is flush with the distal end of the outer elongated element. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end. One or both of proximal occlusion element and distal occlusion element is a compliant balloon, configured to form a funnel shape upon proximal movement of the outer elongated element and/or the inner elongated element.

Variable length catheter for treating a vessel containing thrombus

A method for localized delivery of a therapeutic or diagnostic agent within a vessel is provided. The method provides for adjustability of the length of the treatment area and for reducing of pressure within the treatment area. A catheter system includes an inner elongated element, an outer elongated element positioned coaxially with respect to the inner elongated element, and a blood-release element at a distal end of the inner elongated element. A proximal occlusion element is positioned at the distal end of the outer elongated element, proximal to an outlet port. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end.

Variable length catheter for drug delivery

A catheter system for localized delivery of a therapeutic or diagnostic agent within a vessel is provided. The system provides for adjustability of the length of the treatment area and for reducing of pressure within the treatment area. The catheter system includes an inner elongated element, an outer elongated element positioned coaxially with respect to the inner elongated element, a blood-release element at a distal end of the inner elongated element and a supply elongated element coaxial to the outer elongated element. A proximal occlusion element is positioned at the distal end of the outer elongated element, proximal to an outlet port. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end.
