International Classification:

A61M 31/00
A61M 29/00

US Classification:

604509, 60410103

Abstract:

Methods and apparatus are provided for treating congestive heart by actively or passively enhancing perfusion to the renal arteries. A first embodiment comprises a specially configured balloon catheter and extracorporeal pump, wherein the pump operates in a “once-through” fashion or alternating volume displacement mode. In another embodiment the catheter includes a pair of balloons to isolate a region of the aorta, and a third balloon that directs flow into the renal arteries. In still further embodiments, a stent or cuff having a constricted region is deployed in or around the aorta, respectively, to create a backpressure upstream of the stent or cuff. Methods of enhancing renal perfusion also are provided.

International Classification:

A61B 17/22
A61D 1/02

US Classification:

606159

Abstract:

A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof. The method may further include forcing the opening toward the wall of the vascular site after the advancing step and before the moving step.

International Classification:

A61B 17/22

US Classification:

606159, 606167, 606170

Abstract:

A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both. In some embodiments, the cutting element is movable between retracted and deployed positions for advancing the device to a site for treatment and for removing material, respectively.

International Classification:

A61M 25/00
A61M 29/00

US Classification:

604264, 604 9601

Abstract:

Two renal delivery members have two distal ports that are adapted to be positioned within two renal arteries via their corresponding renal ostia at unique locations along an abdominal aortic wall. A proximal coupler assembly is outside the body and is coupled to deliver material to the two distal ports for bi-lateral renal therapy. One or both of the delivery members may be self-cannulating into the corresponding renal ostium, or may be controllably steered into the respective ostium. Non-occlusive anchors may be coupled with one or both of the delivery members at anchoring positions in the renal artery or abdominal aorta to secure the renal delivery member within the renal artery. Renal-active fluid agents are coupled to the bi-lateral delivery system. Another renal therapy system cannulates a renal vein from the vena cava and controls a retrograde delivery of agents to the respective kidney.
