Valve repair devices for repairing a native valve of a patient

Abstract

An implantable prosthetic device has a coaptation element and at least one anchor. The coaptation element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaptation element can have a structure that is impervious to blood. The coaptation element can be connected to leaflets of the native valve by the anchor.

1 . A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
 a single strip of material;   a coaptation element comprising two or more folded layers of the single strip of material;   a pair of paddles comprising a portion of the single strip of material and connected to the coaptation element, wherein the paddles are movable between an open position and a closed position; and   wherein the paddles are configured to attach to the native valve of the patient.   
     
     
         2 . The valve repair device of  claim 1 , wherein at least a portion of the single strip of material comprises metal strands that are woven together. 
     
     
         3 . The valve repair device of  claim 1 , wherein the paddles comprise an inner paddle portion and an outer paddle portion. 
     
     
         4 . The valve repair device of  claim 1 , wherein the coaptation element is configured to close a gap in the native valve of the patient when the valve repair device is attached to the native valve. 
     
     
         5 . The valve repair device of  claim 1 , wherein the coaptation element and the pair of paddles comprise a plurality of folded layers of the single strip of material. 
     
     
         6 . The valve repair device of  claim 5 , wherein the paddles comprise an inner paddle portion and an outer paddle portion, and the inner paddle portion comprises two folded layers of the plurality of folded layers of the single strip of material. 
     
     
         7 . The valve repair device of  claim 1 , wherein the paddles are disposed over an extension member. 
     
     
         8 . The valve repair device of  claim 7 , wherein the extension member comprises a hoop and a first portion of the single strip of material is folded around the hoop. 
     
     
         9 . The valve repair device of  claim 1 , further comprising a base assembly that comprises:
 a shaft;   a collar that the shaft extends through;   a cap attached to the shaft such that the cap can be moved by the shaft away from the collar;   wherein the pair of paddles are attached to the cap; and   wherein movement of the cap toward the collar causes the pair of paddles to move to the closed position, and movement of the cap away from the collar causes the pair of paddles to move to the open position.   
     
     
         10 . A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
 a single strip of material;   a coaptation element comprising two or more folded layers of the single strip of material;   a collar connected to the coaptation element;   a pair of paddles comprising a portion of the single strip of material and connected to the coaptation element, wherein the paddles are movable between an open position and a closed position; and   wherein the paddles are configured to attach to the native valve of the patient.   
     
     
         11 . The valve repair device of  claim 10 , wherein the collar is connected to a proximal end of the coaptation element. 
     
     
         12 . The valve repair device of  claim 11 , wherein the paddles are connected to a distal end of the coaptation element. 
     
     
         13 . The valve repair device of  claim 10 , wherein a first portion of the single strip of material is woven through at least one opening of the collar. 
     
     
         14 . The valve repair device of  claim 13 , wherein the at least one opening comprises an open slot. 
     
     
         15 . The valve repair device of  claim 13 , further comprising a base assembly that comprises:
 a shaft that extends through the collar;   a cap attached to the shaft such that the cap can be moved by the shaft away from the collar;   wherein both of the pair of paddles are attached to the cap; and   wherein movement of the cap toward the collar causes the pair of paddles to move to the closed position, and movement of the cap away from the collar causes the pair of paddles to move to the open position.   
     
     
         16 . A valve repair device for repairing a native valve of a patient, the valve repair device comprising:
 a single strip of material;   a coaptation element comprising two or more folded layers of the single strip of material;   a pair of extension members, each extension member having attachment portions;   a pair of paddles comprising a portion of the single strip of material, wherein the paddles are movable between an open position and a closed position, are disposed over the extension member, and are configured to attach to the native valve of the patient; and   a cap attached to the paddles, wherein movement of the cap toward the coaptation element causes the pair of paddles to move to the closed position, and movement of the cap away from the coaptation element causes the pair of paddles to move to the open position.   
     
     
         17 . The valve repair device of  claim 16 , further comprising:
 a collar attached to the coaptation element;   a shaft extending through the collar to attach to the cap such that the cap can be moved by the shaft away from the collar; and   
       wherein movement of the cap toward the collar causes the pair of paddles to move to the closed position, and movement of the cap away from the collar causes the pair of paddles to move to the open position.
