Abstract: A method for inducing weight loss in a patient, the method comprising delivering an apparatus to a target area in the blood vessel. The apparatus includes a first portion for preventing migration of the apparatus from the target area within the blood vessel, and a second portion that remains implanted in the blood vessel after deployment of the apparatus at the target area in the blood vessel and is configured to selectively expand and contract to provide partial or full occlusion of the blood vessel. The method further comprises expanding the second portion of the apparatus to at least partially occlude the blood vessel, allowing a period of time to pass after deployment of the apparatus to the target area in the blood vessel, contracting the second portion, and removing at least the second portion of the apparatus from the blood vessel.

Abstract: A method for inducing weight loss in a patient, the method comprising: intentionally occluding a blood vessel so as to create hypoperfusion in a gastrointestinal organ serviced by the blood vessel, whereby to interfere with normal gastrointestinal function and thereby induce weight loss in a patient.

Abstract: Fluid pressure or flow in a human body may be adjusted with circulation or perfusion systems and methods. The system may include a first pump implantable in a chamber or vessel of the human body, and a plurality of struts connected to a housing of the first pump, wherein the struts secure the first pump in a desired location of the chamber or vessel. The system may also include one or more flow modification elements disposed on the first pump, where the flow modification elements direct flow to a desired organ or a desired vessel to adjust pressure or flow as desired.

Abstract: An apparatus for percutaneously implanting an aortic valve prosthesis includes a pump for pumping oxygenated blood from the left atrium into the descending aorta, during a period of time in which an aortic valve prosthesis is being implanted within a diseased aortic valve. First and second catheters are associated with the pump, and a third catheter has an end which is adapted for insertion into the ascending aorta, and the third catheter has an aortic valve prosthesis associated with another end of the third catheter.
