BLOOD VESSEL PROSTHESIS AND DELIVERY APPARATUS
First Claim
1. Prosthesis delivery apparatus for delivering a prosthesis to the branch region of the ascending aorta and the right and left coronary arteries, the apparatus comprising:
- a prosthesis comprising a main conduit and first and second branch conduits,a first guide wire for inserting in the ascending aorta such that it extends through the ascending aorta into the right coronary artery; and
a second guide wire for inserting in the ascending aorta such that it extends through the ascending aorta into the left coronary artery;
wherein the prosthesis is arranged such that;
the first and second branch conduits are movable along the first and second guide wires to the branch region, andthe first branch conduit is movable from a first position in which it projects inside the main conduit, to a second position in which it projects out from the main conduit for location in the right coronary artery, the first branch conduit being arranged to turn inside out as it moves from the first position to the second position, andthe second branch conduit is movable from a first position in which it projects inside the main conduit to a second position in which it projects out from the main conduit for location in the left coronary artery, the second branch conduit being arranged to turn inside out as it moves from the first position to the second position.

Abstract
A prosthesis delivery apparatus, a method of delivering a prosthesis, and a prosthesis are provided. The prosthesis (3) is for delivering to the branch region of the ascending aorta (1) and the right and left coronary arteries (12, 13), and it comprises a main conduit (33) and first and second branch conduits (31, 32). The branch conduits (31, 32) are or locating in the right and left coronary arteries (12, 13) respectively upon moving from a first position in which they are located in the main conduit (33) to a second position in which they project out from the main conduit (33). The branch conduits (31, 32) turn inside out as the move from the first position to the second position.

14. A prosthesis for locating at the branch region of the ascending aorta and the right and left coronary arteries, the prosthesis comprising a main conduit and first and second branch conduits, the first branch conduit being for locating in the right coronary artery and the second branch conduit being for locating in the left coronary artery, wherein:
-
the first branch conduit is movable from a first position in which it projects inside the main conduit to a second position in which projects out from the main conduit in order for it to locate in the right coronary artery, the first branch conduit being arranged to turn inside out as it moves from the first position to the second position, and the second branch conduit is movable from a first position in which it projects inside the main conduit to a second position in which projects out from the main conduit in order for it to locate in the left coronary artery, the second branch conduit being arranged to turn inside out as it moves from the first position to the second position. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

28. A method for delivering a prosthesis to the branch region of the ascending aorta and the right and left coronary arteries, the prosthesis comprising a main conduit and first and second branch conduits, the method comprising the steps of:
-
inserting a first guide wire in the ascending aorta such that it extends through the ascending aorta into the right coronary artery; inserting a second guide wire in the ascending aorta such that it extends through the ascending aorta into the left coronary artery. moving the prosthesis to the branch region by moving the first branch conduit along the first guide wire and the second branch conduit along the second guide wire; and moving the first branch conduit along the first guide wire from a first position in which it projects inside the main conduit to a second position in which it projects out from the main conduit, to locate the first branch conduit in the right coronary artery, the first branch conduit turning inside out as it moves from the first position to the second position; moving the second branch conduit along the second guide wire from a first position in which it projects inside the main conduit to a second position in which it projects out from the main conduit, to locate the second branch conduit in the left coronary artery, the second branch conduit turning inside out as it moves from the first position to the second position. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
