Embodiment Construction

[0040] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the subject technology. It should be understood that the subject technology may be practiced without some of these specific details. In other instances, well-known structures and techniques have not been shown in detail in order to avoid obscuring the subject technology.

[0041] Moreover, while this disclosure sets forth specific details of various embodiments, it should be appreciated that this description is exemplary only and should not be construed in any way as limiting. Additionally, it is contemplated that although particular embodiments of the present disclosure may be disclosed or illustrated in the context of an aortic valve prosthesis, such embodiments may also be used in other cardiac valve prosthetic applications. In addition, various applications of this type of embodiment and its variants that can be imagined by those skilled in...

Abstract

The present disclosure relates to a heart valve prosthesis. The heart valve prosthesis includes a valve anchor having at least one U-shaped member extending about a longitudinal axis of the valve anchor, the U-shaped member having a peak and a base, the peak having an engagement region, the valve anchor being expandable from the compression configuration, Engaging an autologous valve structure; anexpandable valve holder having a compressed configuration, an expanded configuration, a first end and a second end, the flap being configured to expand within the valve anchor at the native valve structure; and a coupling mechanism that will The valve anchor is interconnected with the valve holder, the coupling mechanism is coupled to the valve holder and slidably coupled to the U-shaped member,and the coupling mechanism is slidable from the base along the U-shaped member and captured in the joint region of the peak portion, wherein The coupling mechanism limits axial movement of the valve holder relative to the valve anchor when captured within the engagement region of the peak.

Description

technical field [0001] The present invention relates to devices and methods for the percutaneous delivery and implantation of heart valve prostheses. [0002] The valve prosthesis can be delivered to the defective native valve in a compressed state within a sheath and released in situ. Background technique [0003] Prosthetic heart valves are used to replace damaged or diseased heart valves. In vertebrates, the heart is a muscular organ with four pumping chambers: left atrium, right atrium, left ventricle, and right ventricle, each of which is provided with its own unidirectional valve. Native heart valves were identified as aortic, mitral (or mitral), tricuspid, and pulmonary. Although repair or replacement of the aortic or mitral valves is more common (because they are located on the left side of the heart where stress is greatest), artificial heart valves can be used to replace any of these natively formed valves. [0004] Traditional heart valve replacement surgery i...
