The present invention discloses devices and methods for performing intravascular procedures
without cardiac bypass. The devices include various embodiments of temporary filter devices (10),
temporary valves (26), and prosthetic valves (90). The temporary filter devices (10) have one or
more cannulae (2) which provide access for surgical tools for effecting repair of the cardiac valves.
A cannula (2) may have filters (3) of various configurations encircling the distal region of the
cannula, which prevents embolism material from entering the cornonary arteries, and aorta. The
temporary valve devices (26) may also have one or more cannulae (2) which guide insertion of the
valve into the aorta. The valve devices (26) expand in the arorta to occupy the entire flow path of
the vessel. In one embodiment, the temporary valve (26) is a disc of flexible, porous material that
acts to filter blood passing therethrough. A set of valve leaflets extend peripherally from the disc.
These leaflets can alternately collapse to prevent blood flow through the valve, and extend to
permit flow.
