741 results about "Prosthetic valve" patented technology

A prosthetic valve refers to a valve used in or right outside of the heart to replace an injured, damaged or missing heart valve. There are four places in the heart structure in which prosthetic valves may be used. These are the mitral and tricuspid valves, and the aortic valve (aorta) and pulmonary valve.

Kit enabling a prosthetic valve to be placed in a body enabling a prosthetic valve to be put into place in a duct in the body

InactiveUS20050043790A1Destruction damageRisk of destructionHeart valvesBlood vesselsProsthetic valveInsertion stent
The present invention is an assembly comprising a prosthetic valve to be implanted; a radially expandable stent comprising at least one zone intended to be expanded to allow the stent, in the expanded state, to bear against the wall of the body duct to be fitted with the valve, this bearing making it possible to immobilize this stent with respect to this wall; and means for mounting the valve with respect to the stent, making it possible to connect the valve to the stent in such a way that the placement of the stent allows the valve to be mounted in the body duct, and expansion means such as a balloon catheter being provided to trigger expansion of the stent at the implantation site. According to the invention, the valve and the stent are designed in such a way that, at the moment when the stent is expanded, the valve is situated outside the zone or zones of the stent that are subjected to said expansion means. The invention thus consists in separating the valve and said zone or zones to be expanded, so that the expansion of the stent can be effected with an expansion force suitable for perfect anchoring of this stent in the wall of the body duct to be fitted with the valve, and without any risk of destruction or damage of the valve.

Cardiac valve procedure methods and devices

The present invention discloses devices and methods for performing intravascular procedures with out 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.
