    Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

    Abstract translation: 一种假体心脏瓣膜，其构造成代替天然心脏瓣膜并用于植入后扩张，并且在体外植入物后面具有可从其上观察到的瓣膜型指示器。 指示器传达关于阀的信息，例如阀的尺寸或孔直径，和/或阀具有用于植入物扩张的能力。 指示符可以是代表关于阀的特性的信息的字母数字符号或其他符号或符号的组合，例如阀的尺寸。 植入后扩张的能力有利于瓣膜瓣膜手术，其中瓣膜型指示器向外科医生传达关于植入的瓣膜是否适于手术并且通知二次瓣膜的选择的信息。

    Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.

    Abstract translation: 用于人类植入物的假体心脏瓣膜。 该阀包括具有起伏的流入尖端和流出接合柱的线形，柔性叶片在流动区域中附着和弯曲。 每个小叶可以悬挂在尖端区域的线形顶部，但是在接合柱处具有各自延伸在线形下方的突片，以便与相邻传单的突片一起固定。 假体心脏瓣膜也可以是双线的线形，其间夹着传单。 一个线形可以比另一个线形大，传单延伸越过较小的线形。 较小的线形可以具有从更大的线形曲线径向向外弯曲的连接，以提供传播片附接到的结构。

    Abstract: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.
