Abstract

Embodiments of a leaflet clip device and a method of reducing regurgitation through a native heart valve are disclosed. The leaflet clamp device can include an elongate clamping member having a first end portion and a second end portion and a tensioning mechanism coupled to the clamping member. The leaflet clamp device can further comprise one or more tensioning members disposed within the lumen of the clamping member, wherein the one or more tensioning members are operatively connected to the tensioning mechanism to release the clamping member from the delivery The configuration is changed to the implanted configuration.

Description

technical field [0001] The present disclosure relates to devices and methods for treating heart valve insufficiency. Background technique [0002] Heart valve insufficiency typically involves the backflow of blood through heart valves that do not close completely or properly, resulting in impaired cardiovascular function. Valvular insufficiency can affect, for example, the mitral, aortic, or tricuspid valves, and can be associated with calcified or prolapsed leaflets, and / or dilation or deformation of the valve annulus. One approach to treating heart valve insufficiency is the use of one or more leaflet clips to improve the coaptation of the native valve leaflets. However, conventional leaflet clips can be difficult to implant, can interfere with or damage the function of associated valve structures such as the chordae, and are often limited to use with a single type of heart valve. Accordingly, improvements in devices and methods for treating heart valve insufficiency are...
