Problems solved by technology

Furthermore, such anchoring devices or portions of the stent that assist in anchoring the prosthetic valve typically extend into and are secured to non-diseased areas of the vasculature if future intervention is required, for example, if the prosthetic valve needs to be removed from the patient. which can lead to complications

Embodiment Construction

[0088] first reference figure 1 , shows a prosthetic aortic heart valve 10 according to one embodiment. The prosthetic valve 10 includes an expandable frame member or stent 12 that supports flexible leaflet segments 14 . The prosthetic valve 10 is radially compressible to a compressed state for delivery through the body to the deployment site and expandable at the deployment site to figure 1 Its functional dimensions are shown. In some embodiments, the prosthetic valve 10 is self-expanding; that is, the prosthetic valve is radially expandable to its functional size when advanced from the distal end of the delivery sheath. Devices particularly suited for percutaneous delivery and implantation of self-expanding prosthetic valves are described in detail below. In other embodiments, the prosthetic valve may be a balloon-expandable prosthetic valve that may be adapted to fit in a compressed state on a balloon of a delivery catheter. The prosthetic valve can be expanded to its f...

Abstract

Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.

Description

technical field [0001] The present invention relates to embodiments of prosthetic valves (eg, prosthetic heart valves) and delivery devices for implanting prosthetic valves. Background technique [0002] Prosthetic heart valves have been used for many years to treat heart valve disease. Native heart valves, such as the aortic, pulmonary, and mitral valves, play a key role in ensuring an adequate supply of blood to flow forward through the cardiovascular system. Congenital, inflammatory or infectious conditions can make these heart valves less effective. Such damage to the valves can lead to severe cardiovascular damage or death. For many years, the definitive treatment for this disease has been surgical repair or valve replacement during open-heart surgery, but such surgery is prone to many complications. More recently, transvascular techniques have been developed to introduce and implant prosthetic heart valves using flexible catheters in a less invasive manner than open...
