    • A system for delivering and deploying a self-expandable heart valve to a site of implantation such as the aortic annulus includes a deployment mechanism that engages the valve and regulates the rate of expansion of both the proximal and distal ends thereof. The heart valve may be a rolled-type valve and the deployment mechanism may include a plurality of distal fingers and a plurality of proximal fingers that engage the outer layer of the head valve. Controlled radial movement of the fingers regulates the unwinding of the rolled heart valve. The fingers may be removed prior to inflation of a balloon to fully expand the valve, or the fingers may be repositioned to the inside of the valve for this purpose. The deployment mechanism may include an umbrella structure that forces the rolled valve outward into its fully expanded configuration. Alternatively, a gear shaft that engages one or more gear tracks on the valve may be utilized to regulate expansion of the valve. A stabilization balloon may be used to axially and radially locate the deployment mechanism relative to the site of implantation. Methods of operation of the delivery and deployment mechanism include regulating the rate of self-expansion of the valve and forcing the valve outward into its fully expanded configuration utilizing the same or different means.
    • 用于将自扩张心脏瓣膜递送和部署到诸如主动脉瓣环的植入部位的系统包括与阀门接合并调节其近端和远端的膨胀速率的展开机构。 心脏瓣膜可以是卷状阀,并且展开机构可以包括多个远侧指状物和与头部阀门的外层接合的多个近端指状物。 手指的受控径向运动调节卷绕的心脏瓣膜的展开。 在气囊膨胀之前可以将手指移除以完全膨胀阀,或者为了这个目的,手指可以重新定位到阀的内部。 展开机构可以包括伞形结构,其将卷起的阀向外推入其完全展开的构型。 或者,与阀上的一个或多个齿轮啮合的齿轮轴可用于调节阀的膨胀。 可以使用稳定气囊来相对于植入位置轴向地和径向地定位展开机构。 输送和展开机构的操作方法包括利用相同或不同的装置来调节阀的自膨胀速率并迫使阀向外进入其完全膨胀的构型。

    • Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes. The one-piece stents may include an annulus anchoring section, a sinus section with the membranes attached over sinus apertures, and a rigid outflow section. The two-piece stent may include a primary stent to provide a tubular base at the annulus, and a secondary stent having the membranes that couples within the primary stent. Lockout tabs to secure the stents in their expanded shapes are provided. Also, alignment structure may be provided to ensure concentric unfurling. Anchoring barbs at the stent edges or in the stent body secure the valve within the annulus. Methods of implantation are also provided.

    • Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery using a catheter, and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes. The stents may include an annulus section, a sinus section with the membranes attached over sinus apertures, and an outflow section. Lockout tabs and making slots secure the stents in their expanded shapes. Alignment structure ensures concentric unfurling of the stent. Anchoring elements at the stent edges or in the stent body secure the valve within the annulus. A method of manufacture includes shape setting the sheet-like stent to ensure an outward bias during deployment. The stent may also include dear tracks for engagement with a gear mechanism for deployment. The stent is desirably made of a superelastic material such as Nitinol and may have areas removed or thinned to reduce the bending stresses when rolled into its small spiral for catheter delivery.
