摘要:
Certain examples of the disclosure concern a docking device for securing a prosthetic valve at a native valve. The docking device includes a coil having a plurality of helical turns when deployed at the native valve, an expandable member extending radially outwardly from the coil and being movable between a radially-compressed/axially-elongated state and a radially-expanded/axially-foreshortened state, and a cover member surrounding an outer surface of the expandable member. A distal end portion of the cover member and a distal end portion of the expandable member are fixedly coupled to the coil via a distal suture including a plurality of knots and a plurality of wraps. A proximal end portion of the expandable member is fixedly coupled to a proximal end portion of the cover member. The proximal end portion of the expandable member and the proximal end portion of the cover member are axially movable relative to the coil.
