Abstract
A parent vessel lies adjacent heart tissue, and a restriction in the parent vessel is bypassed. A first region of the parent vessel on a first side of the restriction is accessed and an aperture is formed therein. A lumen is formed through the heart tissue, and the lumen communicates with the parent vessel through the first aperture. A second aperture is formed in a second region of the parent vessel on a second side of the restriction. The lumen through the heart tissue communicates with the parent vessel through the first and second apertures, thus bypassing the restriction.
Claims19
A method of bypassing a restriction in a coronary parent vessel lying adjacent heart tissue in a heart, the heart communicating with an aorta, the method comprising:
- accessing a first region of the coronary parent vessel on a first side of the restriction;
- forming a first aperture in the coronary parent vessel in the first region;
- forming a lumen through the heart tissue, the lumen communicating with the coronary parent vessel through the first aperture;
- and
- forming a second aperture in a second region of the coronary parent vessel on a second side of the restriction such that the lumen through the heart tissue communicates with the coronary parent vessel through the second aperture.
A method of bypassing a restriction in a coronary parent vessel lying adjacent heart tissue in a heart, the heart communicating with an aorta, the method comprising:
- accessing a first region of the coronary parent vessel on a proximal side of the restriction;
- forming a first aperture in the coronary parent vessel in the first region;
- forming a lumen through the heart tissue, the lumen communicating with the coronary parent vessel through the first aperture, the lumen extending from the first aperture to a region proximate the coronary parent vessel distal of the restriction.
A method of bypassing a restriction in a coronary parent vessel lying adjacent heart tissue in a heart, the heart communicating with an aorta, the method comprising:
- accessing a first region of the coronary parent vessel proximal of the restriction;
- and
- forming a first aperture in the coronary parent vessel in the first region to access the heart tissue;
- forming a lumen through the heart tissue to a region proximate the coronary parent vessel distal of the restriction;
- and
- forming a second aperture in the coronary parent vessel distal of the restriction such that the lumen through the heart communicates with the aorta and with the coronary parent vessel through the first and second aperture in the parent vessel.
