Abstract
The present invention relates to a minimally invasive method of performing annuloplasty. According to one aspect of the present invention, a method for performing annuloplasty includes creating a first plication in the tissue near a mitral valve of a heart, using at least a first plication element, and creating a second plication in the tissue near the mitral valve such that the second plication is substantially coupled to the first plication.
Claims57
A method for performing annuloplasty, the method comprising:
- creating a first plication in the tissue near a mitral valve of a heart, the first plication being created using at least a first plication element;
- and
- creating a second plication in the tissue near the mitral valve, wherein the second plication is substantially coupled to the first plication.
A method for performing annuloplasty, the method comprising:
- accessing a heart to provide a plurality of plication elements to the heart, the plurality of plication elements being provided to the heart through a catheter arrangement, the plication elements including a first anchor arrangement;
- engaging the first anchor arrangement to tissue near a mitral valve of the heart using the catheter arrangement to substantially anchor the first anchor arrangement to the tissue near the mitral valve;
- and
- creating at least a first plication and a second plication using the first anchor arrangement.
1 more element
A method for performing annuloplasty, the method comprising:
- accessing an area of a heart using a catheter arrangement, the catheter arrangement including a first portion;
- temporarily anchoring the first portion of the catheter arrangement to the tissue near the mitral valve of the heart;
- providing an anchor element to the area;
- and
- engaging the anchor element to the tissue near the mitral valve, wherein the first portion of the catheter arrangement is arranged to substantially provide a counter-traction force associated with engaging the anchor element.
2 more elements
A method for performing annuloplasty, the method comprising:
- accessing an area of a heart using a catheter arrangement, the catheter arrangement including a first portion;
- temporarily anchoring the first portion of the catheter arrangement to the tissue near the mitral valve of the heart;
- providing an anchor element to the area;
- and
- engaging the anchor element to the tissue near the mitral valve, wherein the first portion of the catheter arrangement is arranged to substantially position a tip of the catheter arrangement at the tissue near the mitral valve.
2 more elements
A method for performing annuloplasty, the method comprising:
- accessing an area of a heart to provide a first plication element to the area using a catheter arrangement, the catheter arrangement including a first portion and a second portion;
- substantially anchoring the first portion of the catheter arrangement to tissue near a mitral valve of the heart;
- positioning a tip of the second portion of the catheter arrangement at a first distance from the first portion;
- and
- substantially engaging the first anchor to the tissue near the mitral valve of the heart using the second portion of the catheter arrangement.
2 more elements
A method for performing annuloplasty, the method comprising:
- accessing an area of a heart to provide a first plication element to the area using a catheter arrangement, the catheter arrangement including a deflectable tip area and a pull wire arranged to cause the deflectable tip area to deflect;
- altering a curvature in the tip area to reach tissue near a mitral valve of the heart, wherein altering the curvature includes substantially actively controlling the pull wire;
- and
- engaging the first plication element to the tissue near the mitral valve.
1 more element
A method for performing annuloplasty, the method comprising:
- accessing an area of a heart using a catheter arrangement, the catheter arrangement including a deflectable tip portion and a pull wire arranged to cause the deflectable tip area to deflect;
- altering a curvature in the tip area to reach tissue near a mitral valve of the heart, wherein altering the curvature includes substantially actively controlling the pull wire to position the tip area;
- and
- temporarily engaging the tip area to the tissue near the mitral valve, wherein temporarily engaging the tip area to the tissue near the mitral valve enables the catheter arrangement to deliver at least a first plication element to the tissue near the mitral valve.
1 more element
A method for performing annuloplasty, the method comprising:
- accessing a left ventricle of a heart to provide a first plication element to the left ventricle using a catheter arrangement;
- creating a curvature in the catheter arrangement to reach tissue near a mitral valve of the heart, the curvature being at an orthogonal orientation with respect to the mitral valve;
- and
- engaging the first plication element to the tissue near the mitral valve, wherein engaging the first plication element includes causing the first plication element to substantially pass through a portion of the tissue to substantially anchor the first plication element to the tissue near the mitral valve.
1 more element
An incrementor catheter comprising:
- a first lumen, the first lumen being arranged to track over a wire, the wire being substantially anchored within a left ventricle of a heart;
- and
- a second lumen, the second lumen having a second tip that is arranged to be moved at a distance away from a first tip of the first lumen, wherein the second lumen is arranged to carry and to deploy a plication element.
A method for performing annuloplasty comprising:
- temporarily fixing a helical coil of a first element in tissue near a mitral valve of the heart, the first element including a tail;
- and
- tracking a catheter arrangement over the tail, wherein the catheter arrangement is arranged to substantially permanently fix a second element to the tissue.
