Abstract

A coil is screwed into the heart wall HW between the left ventricle and coronary artery, followed by forming of a channel with laser, plasma, electrical, or mechanical device therethrough.

Claims (19)

1. A method for forming a channel between a heart chamber and a coronary vessel through body tissue, comprising:

screwing a coil into the body tissue between the heart chamber and coronary vessel; and

forming a channel within the coil in the body tissue that connects the heart chamber to the coronary vessel so as to place the heart chamber and the coronary vessel in flow communication with each other, wherein the channel does not include a naturally occurring blood containing anatomical conduit,

wherein the screwing of the coil into the body tissue is completed prior to the forming of the channel.

2. The method of claim 1 , wherein the forming of the channel includes forming the channel via one of a laser device, a plasma ablation device, an electrical device, and a mechanical device.

3. The method of claim 1 , wherein the heart chamber is a left ventricle and the body tissue is a heart wall.

4. The method of claim 3 , wherein the coronary vessel is a coronary artery.

5. The method of claim 1 , further comprising applying a biocompatible material to the channel.

6. The method of claim 1 , further comprising screwing in the coil via a catheter.

7. A method for forming a channel between a first body lumen and a second body lumen through body tissue, comprising:

screwing a coil into the body tissue between the first and second body lumens; and

forming a channel in the body tissue that connects the first body lumen to the second body lumen, the body tissue defining a lumen of the channel,

wherein the coil is not within the lumen of the channel and the lumen of the channel is within the coil.

8. The method of claim 7 , wherein the forming of the channel includes forming the channel via one of a laser device, a plasma ablation device, an electrical device, and a mechanical device.

9. The method of claim 7 , wherein the first body lumen is a heart chamber, the second body lumen is a coronary vessel, and the body tissue is a heart wall.

10. The method of claim 9 , wherein the heart chamber is a left ventricle and the coronary vessel is a coronary artery.

11. The method of claim 7 , further comprising applying a biocompatible material to the channel.

12. The method of claim 7 , further comprising screwing in the coil via a catheter.

13. The method of claim 7 , wherein the screwing of the coil into the body tissue occurs prior to forming the channel.
