摘要： Apparatus for filtering and entrapping debris in the vascular system of a patient, the apparatus including a filter to allow blood to flow therethrough and to restrict passage of debris, wherein the filter captures debris carried in a first direction of blood flow. The apparatus further includes an entrapment mechanism which allows passage of debris and blood therethrough, in the first direction of blood flow and prevents debris passage in a second direction. The entrapment mechanism and filter allow blood and debris therethrough in the first direction of blood flow. The entrapment mechanism prevents debris flow in the second direction of blood flow. A method for filtering and entrapping debris in the vascular system includes inserting the apparatus into the vascular system, allowing blood and debris carried therein to flow through the entrapment mechanism, and removing the apparatus and accumulated debris from the vascular system.

摘要： Devices and methods for performing intravascular procedures without cardiac bypass include embodiments of temporary filter devices, temporary valves, and prosthetic valves. The temporary filter devices have a cannula which provides access for surgical tools for effecting repair of cardiac valves. The cannula may have filters which prevent embolitic material from entering the coronary arteries and aorta. The valve devices may also have a cannula for insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel and operate to prevent blood flow and to permit flow through the valve. The prosthetic valves include valve fixation devices which secure the prosthetic valve to the wall of the vessel. The prosthetic valves are introduced into the vascular system in a compressed state, advanced to the site of implantation, and expanded and secured to the vessel wall.

摘要： The present invention discloses devices and methods for performing intravascular procedures without cardiac bypass. The devices include various embodiments of temporary filter devices, temporary valves, and prosthetic valves.The temporary filter devices have one or more cannulae which provide access for surgical tools for effecting repair of the cardiac valves. A cannula may have filters of various configurations encircling the distal region of the cannula, which prevent embolitic material from entering the coronary arteries and aorta.The temporary valve devices may also have one or more cannulae which guide the insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve 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.The prosthetic valves include valve fixation devices which secure the prosthetic valve to the wall of the vessel. In one embodiment, the prosthetic valves have at least one substantially rigid strut, at least two expandable fixation rings located about the circumference of the base of the apex of the valve, and one or more commissures and leaflets. The prosthetic valves are introduced into the vascular system a compressed state, advanced to the site of implantation, expanded and secured to the vessel wall.
