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.

摘要： A method of treating a diseased cardiac valve can include implanting a valve prosthesis by compressing the valve prosthesis to a compressed state for delivery and expanding the valve prosthesis to an expanded state for deployment. The valve prosthesis can include a valve fixation device having a plurality of struts, a first circumferential row of cells coupled to the struts, and a second circumferential row of cells coupled to the struts. The struts are substantially rigid such that the struts do not change dimensions between the compressed state and the expanded state. The valve prosthesis can also include a plurality of leaflets and a plurality of commissures. The valve is coupled to the valve fixation device such that the commissures are radially aligned with respective struts of the plurality of struts.

摘要： A method of performing an endovascular procedure within a patient can include inserting a filter into the patient's vascular system to restrict the passage of emboli through the filter while allowing blood to flow through the filter. The method can also include inserting a prosthetic valve into the patient's vascular system in a compressed state, and advancing the prosthetic valve to a site of implantation upstream of the filter. Additionally, the method includes implanting the prosthetic valve at the site of implantation by expanding at least a portion of the prosthetic value, and removing the filter from the patient's vascular system.

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.
