Abstract: The present disclosure concerns embodiments and methods of use of an introducer that is adapted to facilitate insertion of a prosthetic device, such as a prosthetic heart valve, into a patient's vasculature. In one embodiment, the introducer comprises an elongated body defining a central lumen extending between distal and proximal ends of the body. The introducer body can also have a longitudinally extending gap extending along the length of the body between the distal end proximal ends. The gap in the introducer allows a user to place the introducer around implant sutures by passing the sutures through the gap and into the central lumen. Similarly, the gap allows the introducer to be easily removed from the sutures and/or a delivery device by passing them outwardly through the gap.

Abstract translation: 本公开涉及使用导引器的实施例和方法，所述导引器适于便于将假体装置（例如假体心脏瓣膜）插入患者的脉管系统中。 在一个实施例中，导引器包括限定在主体的远端和近端之间延伸的中心腔的细长主体。 导引器主体还可以具有沿主体的长度在远端近端之间延伸的纵向延伸的间隙。 引导器中的间隙允许使用者通过使缝线穿过间隙并进入中心腔而将引入器放置在植入物缝合线周围。 类似地，间隙允许导引器通过将其向外通过间隙而从缝线和/或输送装置中容易地移除。

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 coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.
