Systems and methods for reshaping a heart valve

Abstract

The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve. The present disclosure also includes associated methods and systems.

What is claimed is: 
     
         1 . A method of reshaping cardiac tissue, said method comprising:
 axially and rotationally controlling movement of an implantable device having tissue-engaging members configured for engagement with cardiac tissue;   reshaping the cardiac tissue with the implantable device; and   engaging an annular member with the implantable device to maintain the reshaped configuration of the cardiac tissue.   
     
     
         2 . The method of  claim 1 , further comprising engaging the tissue-engaging members on the implantable device with the cardiac tissue and moving the implantable device to reshape the cardiac tissue. 
     
     
         3 . The method of  claim 1 , further comprising moving the annular member axially with respect to the implantable device to engage the annular member with the implantable device. 
     
     
         4 . The method of  claim 1 , further comprising reshaping annular cardiac tissue. 
     
     
         5 . The method of  claim 1 , wherein said method comprises moving the implantable device with respect to cardiac tissue to reshape the cardiac tissue. 
     
     
         6 . The method of  claim 3 , further comprising moving the implantable device with a control handle. 
     
     
         7 . The method of  claim 1 , further comprising moving the annular member toward the cardiac tissue engaged by the implantable device. 
     
     
         8 . The method of  claim 7 , further comprising moving the annular member axially toward the cardiac tissue engaged by the implantable device. 
     
     
         9 . The method of  claim 1 , further comprising axially and rotationally moving the implantable device with respect to cardiac tissue. 
     
     
         10 . A method of reshaping cardiac tissue, said method comprising:
 axially and rotationally controlling movement of an implantable device having tissue-engaging members configured for engagement with cardiac tissue; and   reshaping the cardiac tissue with the implantable device engaged with cardiac tissue.   
     
     
         11 . The method of  claim 10 , further comprising engaging an annular member with the implantable device to maintain the reshaped configuration of the cardiac tissue. 
     
     
         12 . The method of  claim 10 , further comprising reshaping annular cardiac tissue with the implantable device. 
     
     
         13 . The method of  claim 10 , further comprising engaging a securing member with respect to the implantable device to maintain the configuration of the reshaped cardiac tissue. 
     
     
         14 . The method of  claim 10 , further axially and rotationally moving the implantable device with respect to cardiac tissue. 
     
     
         15 . The method of  claim 10 , further comprising engaging tissue-engaging features of the implantable device with cardiac tissue and then moving the implantable device to reshape the cardiac tissue. 
     
     
         16 . A method of reshaping cardiac tissue with an implantable device, said method comprising:
 engaging the implantable device with cardiac tissue;   reshaping the cardiac tissue with the implantable device engaged with the cardiac tissue; and   axially advancing a member of the implantable device to maintain the reshaped configuration of the cardiac tissue.   
     
     
         17 . The method of  claim 16 , further comprising engaging tissue-engaging features of the implantable device with cardiac tissue and then moving the implantable device to reshape the cardiac tissue. 
     
     
         18 . The method of  claim 17 , wherein axially advancing a member of the implantable device comprises axially advancing a member of the implantable device towards the tissue-engaging features. 
     
     
         19 . The method of  claim 16 , further comprising reshaping annular cardiac tissue. 
     
     
         20 . The method of  claim 16 , further comprising moving the implantable device with respect to the cardiac tissue to reshape the configuration of the cardiac tissue.
