Abstract: A system includes a medical device for implanting in a valve of a subject, the implantable medical device having a self-expanding frame; and a holder configured to retain the frame of the implantable medical device in a constricted configuration and to control expansion of the frame. The holder has a controllably constrictable and expandable loop, wherein the loop is disposed about at least a portion of the self-expanding frame such that constriction or expansion of the first loop controls constriction or expansion of the frame.

Abstract: Various embodiments of a prosthetic valve sizer and a method that utilizes such valve sizer are disclosed. In one or more embodiments, the prosthetic valve sizer can include a sizer body including an annular base and a post extending from the annular base. The prosthetic valve sizer can also include a resilient tip extending from the post of the sizer body. The resilient tip can include a material different from and more flexible than a material of the sizer body.

Abstract: A valve prosthesis includes an expandable frame. The expandable frame has an outflow portion and an inflow portion connected to the outflow portion. The frame defines a central lumen extending between the outflow portion and the inflow portion. The frame is generally cylindrical in a fully expanded configuration. When the frame is in the fully expanded configuration, an outer surface of the inflow portion is concave. The inflow portion has an upper inflow portion and a lower inflow portion. When the frame is in the fully expanded configuration, the upper inflow portion flares outwardly from the central lumen of the frame to greater extent than the lower inflow portion.
