Abstract
The percutaneously delivered temporary valve assembly of the present invention, and method of using the same, provides an elongate element and a temporary valve disposed on the elongate element. The temporary valve can comprise struts and a membrane attached to the struts. The elongate element can include at least one lumen. The percutaneously delivered temporary valve assembly can be used to replace an aortic valve by locating a temporary valve in a patient's ascending aorta; deploying the temporary valve; removing the native aortic valve past the temporary valve; implanting the prosthetic aortic valve past the temporary valve; collapsing the temporary valve; and removing the temporary valve from the patient. The temporary valve can be sized to the patient and can be left in place while the prosthetic aortic valve heals in.
