Fixed length anchor and pull mitral valve device and method

A device for effecting mitral valve annulus geometry of a heart, comprising:

• first anchor means for anchoring in the coronary sinus of the heart adjacent the mitral valve annulus;
• second anchor means for being deployed within the heart proximal to the first anchor means and adjacent the mitral valve annulus;
• and
• connecting means having a fixed length and permanently connecting the first anchor means to the second anchor means, whereby
• when the first and second anchor means are within the heart with the first anchor means deployed, the second anchor means may be displaced proximally for cooperating with the first anchor means and the connecting means for effecting the geometry of the mitral valve annulus and released for maintaining the effect on the mitral valve geometry.

A system that effects mitral valve annulus geometry of a heart, comprising:

• a mitral valve device including 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, a second anchor configured to be positioned within the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart, and a connecting member having a fixed length permanently attached to the first and second anchors;
• a catheter having a distal end, a proximal end and a lumen that receives the device, the catheter being guidable into the coronary sinus adjacent to the mitral valve annulus and deploying the first and second anchors of the device within the coronary sinus adjacent to the mitral valve annulus;
• and
• a tether releasably coupled to the second anchor and extending proximally through the lumen and out of the catheter proximal end, whereby
• when the first anchor is deployed by the catheter in the coronary sinus, the second anchor may be displaced proximally by proximally pulling on the tether to effect the geometry of the mitral valve annulus and thereafter released for deployment to maintain the effect on the mitral valve geometry.

A method of effecting mitral valve annulus geometry in a heart, the method including the steps of:

• fixing a first anchor within the coronary sinus of the heart adjacent to the mitral valve annulus;
• positioning a second anchor within the heart proximal to the first anchor;
• fixing a fixed length connecting member between the first anchor and the second anchor;
• displacing the second anchor proximally to effect the geometry of the mitral valve annulus;
• and
• releasing the second anchor from further proximal displacement to maintain the effect on the mitral valve geometry.

A method of effecting mitral valve geometry of a heart, the method including the steps of:

• advancing a guide catheter into the coronary sinus of the heart adjacent to the mitral valve annulus;
• feeding a self-deploying first anchor down and out of the guide catheter to deploy the first anchor in the coronary sinus adjacent to the mitral valve annulus;
• connecting a fixed length connecting member between the first anchor and a self-deploying second anchor that once deployed anchors at least against distal movement;
• guiding the second self-deploying anchor down the guide catheter to a position within the coronary sinus proximal to the first anchor;
• displacing the second anchor proximally to effect the geometry of the mitral valve annulus;
• withdrawing the guide catheter to release and deploy the second anchor;
• and
• releasing the second anchor to deploy the second anchor and maintain the effect on the mitral valve annulus geometry.

A device that effects mitral valve annulus geometry of a heart, comprising:

• 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;
• a second anchor configured to be positioned within the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart;
• and
• a connecting member attached between the first and second anchors,
• at least one of the first and second anchors anchoring against movement in a first direction and being moveable in a second direction opposite the first direction.

A device that effects mitral valve annulus geometry of a heart, comprising:

• 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;
• a second anchor configured to be positioned within the heart proximal to the first anchor and adjacent the mitral valve annulus within the heart;
• and
• a connecting member attached between the first and second anchors,
• the first anchor being configured to occupy less than all of the coronary sinus to permit a cardiac lead to be passed by the first anchor.
