    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable stent frame, thereby enabling attachment to the annulus without sutures. The prosthetic valve may be a commercially available valve with a sewing ring and the stent frame attached thereto. The stent frame may expand from a conical deployment shape to a conical expanded shape, and may have a cloth covering its entirety as well as a plush sealing flange around its periphery to prevent paravalvular leaking.

    Abstract translation: 提供了一种快速连接的心脏瓣膜假体，可以在手术过程中快速方便地植入。 心脏瓣膜包括基本上不可膨胀的不可压缩的人造瓣膜和塑性扩张的支架框架，从而能够在没有缝线的情况下附接到环形空间。 假体瓣膜可以是具有缝合环的市售阀，并且支架框架附接到其上。 支架框架可以从锥形展开形状扩展成圆锥形膨胀形状，并且可以具有覆盖其整体的布以及围绕其周边的毛绒密封凸缘，以防止瓣膜泄漏。

    Abstract: Methods of quickly and easily implanting a quick-connect heart valve prosthesis during a surgical procedure are provided. The heart valve may include a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A system and method for deployment includes an integrated handle shaft and balloon catheter. A safety member disposed between the balloon catheter and handle shaft prevents premature catheter advancement prior to heart valve placement at the annulus, and also may prevent premature balloon inflation prior to full catheter advancement.

    Abstract translation: 提供了在外科手术过程中快速和容易地植入快速连接心脏瓣膜假体的方法。 心脏瓣膜可以包括基本上不可膨胀的，不可压缩的人造瓣膜和可塑性可扩张的框架，从而使得能够在没有缝线的情况下附接到环形区域。 一种用于部署的系统和方法包括一体式手柄轴和球囊导管。 设置在球囊导管和手柄轴之间的安全构件防止在心瓣膜置于环形空间之前过早的导管前进，并且还可以在全导管前进之前防止过早的球囊膨胀。

    Abstract: A sewing ring for prosthetic heart valves that is connected and configured to pivot outward. A biocompatible fabric covering surrounds at least a portion of the sewing ring, and the ring may be exclusively connected to a stent with the fabric. The sewing ring may be generally planar and of uniform thickness, or may be of varying thickness. The fabric may be used to encompass both the stent and the sewing ring, and may be a single piece. A seam may be provided in the fabric as a discrete pivoting line. The sewing ring may be convertible between bi-stable positions. The ring may extend outward in a frusto-conical shape so as to enable inversion between a position facing the inflow end of the valve and a position facing the outflow end of the valve. A method of implantation, and a method of assembly of the heart valve is also provided.

    Abstract translation: 用于假心脏瓣膜的缝合环，其被连接并构造成向外枢转。 生物相容性织物覆盖物围绕缝合环的至少一部分，并且环可以仅与织物连接到支架上。 缝合环可以是大致平面的并且具有均匀的厚度，或者可以是变化的厚度。 织物可以用于包围支架和缝合环，并且可以是单件。 可以在织物中提供接缝作为离散的枢转线。 缝合环可以在双稳态位置之间转换。 环可以以截头圆锥形的形式向外延伸，以便能够在面对阀的流入端的位置与面向阀的流出端的位置之间发生反转。 还提供了一种植入方法和心脏瓣膜的组装方法。

The sewing ring may have a compliant insert having a celled construction defined by outer walls and inner ribs. A method of implantation, and a method of assembly of the heart valve is also provided.
