The valve construct includes: an annular portion defining an aperture and being connected to the frame for positioning the valve construct within the central cavity of the frame, and a plurality of leaflets extending longitudinally and radially inward from the annular portion. The frame and valve construct are transitionable to a deployed state, in which a diameter of at least a portion of the frame and the valve construct substantially conform to a diameter of a tricuspid and/or mitral valve opening.

Abstract: A system and method for sharing and absorbing energy between body parts. In one particular aspect, the system facilitates absorbing energy between members forming a joint such as between articulating bones.

Abstract: A method and apparatus are disclosed for providing a compression fixation between a first and further component. The apparatus comprises an elongate body having a head end and a tip end and comprising a screw thread including a first region in which the screw thread has a corresponding first pitch and a further region, extending from the tip end, in which the screw thread is tapered and has a corresponding farther pitch that continually decreases away from the tip end.

Abstract: A system including a tensioning element and a fixation element, the tensioning element including a connection element configured to be coupled to a fixation element and an anchoring element configured to be coupled to an external fixation point, the tensioning element being operable to apply a tension between the connection element and the anchoring element, the fixation element including a first portion configured to be coupled to the tensioning element and a second portion configured to be coupled to a bone, the tensioning element and the fixation element being configured to cooperate to apply a tension between the bone and an external fixation point when the anchoring element of the tensioning element is coupled to the external fixation point, the second portion of the fixation element is coupled to the bone, and the tensioning element is operated to apply the tension, thereby retaining the bone in a fixed position.

Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. An improved protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.
