Abstract
Methods and devices for the treatment of cardiac valve dysfunction through the placement of lines and anchors. The lines and anchors can form artificial chordae between valve leaflets and the ventricular wall or papillary muscles or connect the two valve leaflets together. The methods and devices offer a mechanism for performing this technique with the heart still beating, and allows for the placement of multiple lines with a single device.
Claims20
A method comprising:
- extending a suction cup from a distal end of a delivery catheter, the suction cup being at a distal end of a suction catheter, and contacting the suction cup to a heart valve leaflet;
- applying a negative pressure through the suction catheter and the suction cup while contacting the suction cup to the heart valve leaflet, thereby at least partially axially collapsing the suction cup;
- and
- deploying a first tissue anchor onto a first location on the heart valve leaflet through the delivery catheter while applying the negative pressure through the suction cup and suction catheter, the first tissue anchor being coupled to a first suture line configured to be secured to a heart wall.

A method comprising:
- contacting a suction cup at a distal end of a suction catheter to a heart valve leaflet;
- applying a negative pressure through the suction catheter and the suction cup while contacting the suction cup to the heart valve leaflet, thereby partially axially collapsing the suction cup while applying the negative pressure through the suction catheter and the suction cup;
- advancing a needle out of the suction cup to pierce the heart valve leaflet while applying the negative pressure through the suction catheter and the suction cup;
- and
- deploying onto the heart valve leaflet an anchor coupled to an artificial cord, wherein the artificial cord comprises a distal portion coupled to the anchor and a proximal portion configured to be secured to a heart wall.

A method comprising:
- advancing a suction catheter into a heart chamber and contacting a suction cup at a distal end of the suction catheter to a heart valve leaflet;
- applying a negative pressure through the suction catheter and the suction cup while contacting the suction cup to the heart valve leaflet, thereby partially axially collapsing the suction cup while applying the negative pressure through the suction catheter and the suction cup;
- and
- securing a line to the heart valve leaflet while applying the negative pressure through the suction catheter and the suction cup.
