Abstract: A device for measuring an internal dimension of a native cardiac valve annulus includes an elongated support member having a proximal portion and a distal portion. A measuring portion is coupled to the distal portion, and an indicator is coupled to the proximal portion of the support member. The measuring portion is biased towards a deployed configuration such that when deployed it applies an outwardly directed radial force to the native valve annulus.

Abstract: 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

Abstract: A heart valve prosthesis includes an expandable prosthetic valve including three valve leaflets coupled to an anchoring structure. The anchoring structure includes an annular member and a plurality of arms movably coupled to the annular member at one end. The free ends of the arms extend radially away from the prosthesis toward a valve annulus. The arms are configured to fit in a space defined between an open native valve leaflet and a wall of a valve sinus. The arms are sufficiently resilient such that they resist downward movement in response to pressure exerted on the prosthesis, facilitating anchorage and stabilization of the prosthesis at the implantation site.
Abstract translation: 心脏瓣膜假体包括可扩张假体瓣膜，其包括联接到锚定结构的三个瓣膜小叶。 锚固结构包括环形构件和在一端可移动地联接到环形构件的多个臂。 臂的自由端径向延伸离开假体朝向瓣膜环。 臂配置成装配在开放的天然瓣膜和阀窦壁之间限定的空间中。 臂具有足够的弹性，使得它们抵抗施加在假体上的压力而抵抗向下运动，便于植入部位处的假体的锚固和稳定。
