Abstract

A leaflet clip has an elongated member including a proximal end portion and a distal end portion, and first and second clipping arms movable between an open position and a closed position. The clipping arms include respective proximal end portions coupled to the proximal end portion of the elongated member, and respective distal end portions extending distally and radially outward relative to the elongated member. The leaflet clip further includes a tubular member coaxially disposed about the elongated member. Axial motion of the tubular member with respect to the elongated member or axial motion of the elongated member with respect to the tubular member causes corresponding movement of the clipping arms between the open and closed positions.

Description

technical field [0001] The present disclosure relates to devices and methods for treating heart valve insufficiency. Background technique [0002] Heart valve insufficiency usually 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 annulus. One approach to treating heart valve insufficiency is the use of one or more leaflet clamps to improve coaptation of the native valve leaflets. However, conventional leaflet clips can be difficult to implant, can interfere with the function of or damage associated valve structures such as the chordae, and are often limited to use with a single type of heart valve. Accordingly, improved devices and methods for treating heart valve insufficiency are desired. Content...
