Abstract

An aspect of the present teachings includes a method of percutaneously treating a paravalvular leakage. In a preferred embodiment, the method includes providing an anchor having an elongate anchor member and a tensioning member, positioning the anchor through a paravalvular leakage, deploying the anchor wherein at least a part of the distal portion of the elongate anchor member is on one side of the paravalvular leakage, and applying tension to the tensioning member so that at least a part of the distal portion of the elongate anchor member transitions from the elongate configuration to the shortened configuration. Another aspect of the present teachings includes a device that can be used in a method of percutaneously treating a paravalvular leakage.

Claims

exact text as granted — not AI-modified
What is claimed is:

         5 . The method of any of  claim 2 , wherein the tensioning member extends from the distal portion to the proximal portion of the elongate anchor member. 
     
     
         6 . The method of  claim 5 , wherein the tensioning member passes through at least two of the first set of openings. 
     
     
         7 . The method of  claim 5 , wherein the tensioning member passes through at least two of the second set of openings. 
     
     
         8 . The method of  claim 1 , wherein the elongate anchor member comprises a first folding line and a second folding line, the first folding line being at an angle with respect to the second folding line. 
     
     
         9 . The method of  claim 2 , further comprising the step of deploying the anchor wherein at least a part of the proximal portion of the elongate anchor member is on the other side of the paravalvular leakage. 
     
     
         10 . The method of  claim 2 , further comprising the step of applying tension to the tensioning member so that at least a part of the proximal portion of the elongate anchor member transitions from the elongate configuration to the shortened configuration. 
     
     
         11 . The method of  claim 1 , further comprising the step of introducing a catheter approximately at the paravalvular leakage. 
     
     
         12 . The method of  claim 11  further comprising the step of withdrawing the catheter to deploy the anchor wherein at least a part of the distal portion of the elongate anchor member is on one side of the paravalvular leakage. 
     
     
         13 . The method of  claim 11 , further comprising the step of withdrawing the catheter to deploy the anchor wherein at least a part of the proximal portion of the elongate anchor member is on the other side of the paravalvular leakage. 
     
     
         14 . The method of  claim 1  comprising the step of locating the paravalvular leakage. 
     
     
         15 . The method of  claim 1 , wherein the elongate anchor member comprises a plurality of panels, wherein a least one of the plurality of panels is defined by a first folding line and a second folding line. 
     
     
         16 . The method of  claim 18 , wherein at least two of the plurality of panels are at least one of substantially overlapping and partially overlapping in the shortened configuration. 
     
     
         17 . The method of  claim 15 , wherein the applying of tension of the tensioning member causes at least two of the plurality of panels to fold along one of the first and second folding line. 
     
     
         18 . The method of  claim 1 , wherein the anchor comprises a second elongate anchor member proximally to the elongate anchor member. 
     
     
         19 . The method of  claim 18 , further comprising the steps of: deploying the anchor, wherein at least a part of the second elongate anchor member is on the other side of the paravalvular leakage; applying tension to the tensioning member so that at least a part of the second elongate anchor member transitions from the elongate configuration to the shortened configuration; 
     
     
         20 . The method of  claim 19 , further comprising introducing a catheter approximately at the paravalvular leakage. 
     
     
         21 . The method of  claim 20 , further comprising the step of withdrawing the catheter to deploy the anchor wherein at least a part of the elongate anchor member is on one side of the paravalvular leakage. 
     
     
         22 . The method of  claim 20 , further comprising the step of withdrawing the catheter to deploy the anchor wherein at least a part of the second elongate anchor member is on the other side of the paravalvular leakage.
