    摘要: Expandable, percutaneously deployable, prosthetic heart valves and systems for minimally invasive replacement of damaged or diseased native aortic valves comprise an expandable, tubular stent body and a unidirectional valve assembly. Embodiments of the stent body comprise an annulus anchoring section, a sinus section, and an outflow section, with the outflow section flared outwardly from the sinus section in an expanded configuration. Embodiments of the stent body are self-expanding, comprising, for example nitinol. The valve assembly disposed within the sinus section of the stent body and sutured thereto. Embodiments of the valve assembly comprise three leaflets, each leaflet comprising a curved outer edge sutured to the sinus section of the stent body, and a coapting free edge. Embodiments of the valve leaflets comprise pericardium, for example, porcine pericardium. Embodiments of the prosthetic heart valve have a contracted configuration dimensioned for percutaneous delivery thereof.

    摘要: 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.

    摘要: 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.
