Embolization particles can be safely delivered to the left gastric artery of a patient by introducing the distal end of a catheter in the patient's left gastric artery, inflating a balloon located near the distal end of the catheter so that the balloon prevents blood from flowing through the left gastric artery, and injecting a mixture of particles and contrast agent into the proximal end of the catheter so that they flow through the catheter. In addition, a path is provided for blood to flow into the catheter through an opening in the sidewall of the catheter at a position that is proximal to the balloon, and out through the distal end of the catheter. This blood flow helps to carry the particles along to their destination in the distal portion of the left gastric artery. The particles are also prevented from flowing into portions of the patient's artery system that are proximal of the balloon.

Selectively delivering particles into the distal portion of the left gastric artery

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

Methods and apparatuses for embolizing an artery in a living subject using a catheter are disclosed. The catheter has a lumen and also has a balloon located near the distal end of the catheter. The distal end of the catheter is introduced into the artery, and the balloon is inflated to form a seal that prevents blood in the artery from flowing past the balloon. A mixture that includes embolic particles and contrast agent is injected through the lumen into the portion of the artery that is distally beyond the balloon. The subject's own blood or another fluid that contains platelets is injected through the lumen into the portion of the artery that is distally beyond the balloon. Subsequently, the balloon is deflated and the distal end of the catheter is withdrawn.

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 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 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 stent having a main body with a proximal end and a distal end section having proximal and distal openings used for treatment of lesions in blood vessels and hollow organs, particularly at the ostium of side branches. The stent adapts to the anatomical configuration of a vessel branch by having at least one oblique end section in at least its expanded state. Truncated versions of the oblique end section are described as well.
