1. A heart valve repair system, comprising:
a delivery sheath having a proximal end and a distal end; and
an implant configured to be coupled to first and second native leaflets of a native heart valve of a patient, the implant comprising:
a frame (1) comprising a braided structure of intertwining strands and (2) having a surface configured to contact an upstream surface of the native heart valve; and
first and second gripping members coupled to the frame, each of the first and second gripping members including (i) a first arm having a first tissue-engaging surface and (ii) a second arm having a second tissue-engaging surface, each of the gripping members configured to clamp a respective one of the native leaflets between the tissue-engaging surfaces of the gripping member,
wherein the implant is disposed in the delivery sheath in a delivery state in which:
the frame has a proximal end, closer to the proximal end of the delivery sheath, and a distal end, closer to the distal end of the delivery sheath,
the frame is shaped to define a wall fully surrounding, from a proximal end of the wall to a distal end of the wall, a central longitudinal axis of the implant, the proximal end of the wall defining a proximal opening of the frame, and the distal end of the wall defining a distal opening of the frame, and
the distal end of the wall is disposed proximally to the entire first tissue-engaging surface of each of the gripping members and proximally to the entire second tissue-engaging surface of each of the gripping members.
