210000003709 Heart Valves Anatomy 0 abstract description 27
210000004115 Mitral Valve Anatomy 0 description title 5
In general, in an aspect, an annulus of a heart valve is caused to dilate to a predetermined configuration by pushing a delivery tool distally through the annulus from one heart chamber to another heart chamber. A valve support is attached to the delivery tool. The valve support has a plurality of barbs or hooks attached thereon. While the annulus is dilated, the valve support is attached to tissue at locations along the annulus by attaching the barbs or hooks to the tissue. After attachment, the support is caused to contract.
causing a catheter to traverse a body lumen to place a delivery tool with a valve support attached to the delivery tool at an annulus of a heart valve, the valve support having a plurality of barbs or hooks attached thereto, and the delivery tool comprising a tapered outer surface having interconnected struts defining apertures;
pushing the delivery tool distally through the annulus from one heart chamber to another heart chamber causing the delivery tool to radially dilate the annulus to a configuration determined by the delivery tool;
while the annulus is dilated, attaching the hooks or barbs into tissue at locations along the annulus;
after the support is attached into the tissue, moving a tip of the delivery tool proximally to rotate the barbs or hooks about the support to embed the barbs or hooks more securely into the tissue; and
causing the valve support to contract to a smaller diameter.
2. The method of claim 1, wherein the valve support is expandable and contractable.
3. The method of claim 1, wherein the support comprises at least one of stainless steel, gold, Nitinol, and a biologically compatible elastomer.
4. The method of claim 1 also including sheathing the valve support before the catheter is caused to traverse the body lumen and unsheathing the valve support in the vicinity of the heart valve.
5. The method of claim 4 in which the sheathing and unsheathing include moving the catheter and a sheath relative to one another to cause the valve support to be compressed and expanded, respectively.
6. The method of claim 1, wherein the hooks comprise at least one of platinum, gold, palladium, rhenium, tantalum, tungsten, molybdenum, nickel, cobalt, stainless steel, Nitinol, and alloys thereof.
causing a catheter to traverse a body lumen to place a delivery tool with a valve support attached to the delivery tool at an annulus of a heart valve, the valve support having a plurality of barbs or hooks attached thereto, and the delivery tool comprising a self-expanding, semi-rigid net;
8. The method of claim 7, wherein the valve support is expandable and contractable.
9. The method of claim 7, wherein the support comprises at least one of stainless steel, gold, Nitinol, and a biologically compatible elastomer.
10. The method of claim 7 also including sheathing the valve support before the catheter is caused to traverse the body lumen and unsheathing the valve support in the vicinity of the heart valve.
11. The method of claim 10 in which the sheathing and unsheathing include moving the catheter and a sheath relative to one another to cause the valve support to be compressed and expanded, respectively.
12. The method of claim 7, wherein the hooks comprise at least one of platinum, gold, palladium, rhenium, tantalum, tungsten, molybdenum, nickel, cobalt, stainless steel, Nitinol, and alloys thereof.
