Abstract
A prosthesis for locating at a branch region of a blood vessel. The prosthesis comprises a main conduit (10) having a tubular portion (11) with first and second ends (12,13), and at least one projecting portion (14,15,16) projecting from the first end of the tubular portion. One or more branch conduits (17,18) are connected to, and extend from the projecting portions or the tubular portion at a position adjacent the projecting portions. Portions of the prosthesis to which the branch conduits are attached may be more flexible and/or elastic than other portions of the prosthesis.

25. A prosthesis for locating at a branch region of a blood vessel, the prosthesis comprising:
-
a main conduit having walls extending between first and second ends of the main conduit, and one or more branch conduits; wherein the walls of the main conduit comprise a first section and a second section, the second section being more flexible than the first section, more elastic than the first section, or a combination thereof, and wherein the one or more branch conduits are connected to, and extend from the second section. - View Dependent Claims (26, 27, 28, 29, 30)

31. A prosthesis for locating at the branch region of the aortic root where the aorta meets the right and left coronary arteries, the prosthesis comprising
a main conduit for locating in the aorta, the main conduit having first and second ends, the first end being for locating in the aortic root upstream of the second end, and a first branch conduit connected to the main conduit at a position located between the first and second ends of the main conduit, the first branch conduit being for locating in one of the left and right coronary arteries, and a prosthetic aortic valve, wherein the distance between the connection position of the first branch conduit with the main conduit and the first end of the main conduit is such that, when the first branch conduit is located in one of the left and right coronary arteries, the first end of the main conduit extends in the aortic root to a position at which it presses against the aortic valve, maintaining the aortic valve in an open position.

34. A catheter apparatus for delivering a prosthesis to a branch region of a blood vessel, the prosthesis comprising a main conduit and one or more branch conduits, the catheter apparatus comprising:
-
a core catheter having a distal end and a proximal end; a push element provided at the distal end of the core catheter for engaging and pushing the prosthesis, and one or more push actuators for pushing the one or more branch conduits of the prosthesis, wherein the actuators are slidably mounted to the push element. - View Dependent Claims (35, 36, 37)
