Fixed length anchor and pull mitral valve device and method

Abstract

A device affects the mitral valve annulus geometry of a heart. The device includes a first anchor configured to be positioned within and anchored to the coronary sinus of the heart adjacent the mitral valve annulus within the heart and a second anchor configured to be positioned within the coronary sinus of the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart. The second anchor, when deployed, anchors against distal movement and is moveable in a proximal direction. The device further includes a connecting member having a fixed length permanently attached to the first and second anchors. As a result, when the first and second anchors are within the coronary sinus with the first anchor anchored in the coronary sinus, the second anchor may be displaced proximally to affect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry.

1 . A device that affects mitral valve annulus geometry of a heart, comprising: 
 a first anchor, a second anchor and a connecting member; said first anchor configured to be anchored in a coronary sinus; said second anchor configured to be deployed adjacent the mitral valve annulus; whereby the first anchor is positioned in the coronary sinus and the second anchor is deployed proximal of the first anchor to affect and maintain a desired geometry of the mitral valve annulus.    
   
   
       2 . The device of  claim 1  wherein the first anchor is anchored proximal to a crossover point located between a coronary sinus and the cimcumflex artery.  
   
   
       3 . The device of  claim 2  wherein the proximal anchor is positioned in the coronary sinus distal to an ostium of the coronary sinus.  
   
   
       4 . The device of  claim 3  wherein the connecting member has an arcuate configuration.  
   
   
       5 . The device of  claim 4  wherein a tension applied to the connecting member affects the geometry of the mitral valve annulus.  
   
   
       6 . The device of  claim 5  wherein the tension is applied by applying a force on the second anchor.  
   
   
       7 . The device of  claim 6  wherein the device further comprises a tension applying member releasably coupled to the second anchor.  
   
   
       8 . The device of  claim 6  wherein a desired level of tension is applied in order to affect a concomitant change in the geometry of the mitral valve annulus.  
   
   
       9 . The device of  claim 7  wherein the second member is decoupled from the second anchor after the desired change in mitral valve geometry is achieved.  
   
   
       10 . The device of  claim 8  wherein the desired change in the geometry of the mitral valve annulus is monitored.  
   
   
       11 . The device of  claim 8  wherein the desired changed in the geometry of the mitral valve annulus is indicated by a change in a patient's mitral valve regurgitation.  
   
   
       12 . The device of  claim 8  wherein change in the geometry of the mitral valve annulus reduces mitral valve regurgitation.  
   
   
       13 . The device of  claim 1  wherein the connecting member is configured to be atraumatic.  
   
   
       14 . The device of  claim 8  wherein the device further comprises a covering.  
   
   
       15 . The device of  claim 1  wherein the first anchor, the second anchor and connecting members are integral.  
   
   
       16 . A device that affects mitral valve annulus geometry of a heart, comprising: 
 a first anchor configured to be positioned within and anchored to the coronary sinus adjacent the mitral valve annulus;    a second anchor configured to be positioned proximal to the first anchor and adjacent the mitral valve annulus;    a connecting member disposed between the first and second anchors, whereby the first anchor is anchored in the coronary sinus, the second anchor is displaced proximally to affect the geometry of the mitral valve annulus and released to maintain the effect on the mitral valve geometry;    an atraumatic covering; and    at least one loop disposed on the proximal or distal anchor.
