Patent number: 9895223Abstract: A prosthesis for implantation at an implantation site proximate a native aortic valve, the implantation site including a valve annulus and a plurality of Valsalva sinuses located distal to the valve annulus. The prosthesis comprises an armature and a valve connected to the armature, wherein the armature includes a proximal portion configured for anchorage to the valve annulus, a distal portion configured to be positioned distal to the Valsalva sinuses when the proximal portion is anchored to the valve annulus, and first, second and third Valsalva sinus anchors each extending between and connecting the proximal and distal portions and arching radially outward between the proximal portion and the distal portion. The Valsalva sinus anchors are positioned so that each can extend into and engage a wall of a different one of the Valsalva sinuses.Type: GrantFiled: October 20, 2016Date of Patent: February 20, 2018Assignee: Sorin Group Italia S.r.l.Inventors: Carla Stacchino, Giovanni Bergamasco, Gaetano Burriesci, Giovanni Righini

Patent number: 8539662Abstract: A cardiac-valve prosthesis which can be used, for example, as a valve for percutaneous implantation. The prosthesis includes an armature for anchorage of the valve prosthesis in the implantation site. The armature defines a lumen for passage of the blood flow and supports a set of prosthetic valve leaflets, which, under the action of the blood flow, are able to move into a radially divaricated condition to enable the flow of the blood through the lumen in a first direction and a radially contracted condition, in which the valve leaflets co-operate with one another and block the flow of the blood through the prosthesis in the opposite direction. The armature includes, in one embodiment, two annular elements connected by anchor members having the capacity of projecting radially with respect to the prosthesis, and support members for the set of leaflets, the support members being carried by at least one of the annular elements so as to leave substantially disengaged the aforesaid lumen for passage of the blood.Type: GrantFiled: June 16, 2008Date of Patent: September 24, 2013Assignee: Sorin Group Italia S.r.l.Inventors: Carla Stacchino, Giovanni Bergamasco, Gaetano Burriesci, Giovanni Righini

Patent number: 8540768Abstract: A cardiac valve prosthesis includes a frame and a set of prosthetic valve leaflets supported by the frame. The frame defines a principal axis of the cardiac valve prosthesis and includes first and second annular elements expandable from a radially contracted state to a radially expanded state, a plurality of valve supports supporting the leaflets, and a plurality of connecting members. The valve supports are angularly spaced from one another about the principal axis of the cardiac valve prosthesis, and the connecting members extend between and connect the first and second annular elements. When the annular elements are in the radially expanded state each of the connecting members arches radially outward with respect to the annular elements and is configured to project into one of the Valsalva sinuses when implanted. The connecting members are angularly spaced from the valve supports about the principal axis.Type: GrantFiled: December 30, 2011Date of Patent: September 24, 2013Assignee: Sorin Group Italia S.r.l.Inventors: Carla Stacchino, Giovanni Bergamasco, Gaetano Burriesci, Giovanni Righini
