    Abstract: The present invention provides a prosthetic heart valve device that has a frame, and a leaflet assembly having a plurality of leaflets that are secured to the frame. The frame is defined by an annular body and has three spaced-apart commissure regions, each commissure region having a commissure post extending from a proximal outflow end of the frame. A first clipping arm and a second clipping arm extend from opposite sides of each commissure post, each clipping arm extending from each commissure post at an obtuse angle with respect to each commissure post. Each clipping arm has a free end with a tip provided at the free end. The body has a first diameter at a location where the tips of the clipping arms are located, and the tips of the clipping arms extend away from define a second diameter, with the second diameter being greater than or equal to the first diameter.

    Abstract: The present invention provides a system and method for retaining, positioning and releasing a prosthetic heart valve. The system includes a valve holder, and a control handle. The valve holder includes a connection base and at least one holding arm. The holding arms are distributed around a periphery of the connection base, with the holding arms having positioning structures at the distal side thereof for engaging with an outflow side of the prosthetic heart valve. The control handle is coupled to the valve holder for controlling the valve holder.

    Abstract: The present application relates to a separately releasable aortic valve stent, which includes a valve sewing segment, a positioning member, and a prosthetic valve. The prosthetic valve is connected to the valve sewing segment. The valve sewing segment and the positioning member are two independent components and connected to each other via a guiding device. The positioning member is able to be released prior to the valve sewing segment. A slide connection structure is disposed on the valve sewing segment. One end of the guiding device is connected to the positioning member, and another end of the guiding device passed through the slide connection structure is connected to the positioning member. The valve sewing segment is slidable along the guiding device.

    Abstract: Provided is a flexible stent with which it is possible to further improve visibility of an impermeable member which is disposed upon a stent and to further improve operability of the stent. Provided is a flexible stent 11, comprising: a plurality of ring-shaped pattern bodies 13 which have a wavy line-shaped pattern and are positioned side by side in an axial direction LD; and a plurality of connecting elements 15 which connect the adjacent ring-shaped pattern bodies 13. When viewed in a radial direction RD which is perpendicular to the axial direction LD, a ring direction CD of the ring-shaped pattern bodies 13 is or is not oblique with respect to the radial direction RD. A plurality of impermeable members 31 which are highly impermeable to radiation are disposed upon and/or positioned in proximity to struts which configure the ring-shaped pattern bodies 13 and/or the connecting elements 15. The plurality of impermeable members 31 are arrayed regularly along one or more of the ring direction CD, an axial direction LD, or a circumference direction of the flexible stent.

    Abstract: The present disclosure provides a compound three-dimensional surgical implant and methods of forming and using the same. The compound three-dimensional surgical implant includes a grip-type knit mesh defining pores and including a plurality of spiked naps extending from a surface the grip-type knit mesh, a prosthetic knit mesh defining principal cells and peripheral cells being layered on the grip-type knit mesh such that at least a portion of the spiked naps grip at least a portion of the cells of the prosthetic knit mesh. The grip-type knit mesh and the prosthetic knit mesh are folded together into a predetermined three-dimensional structure such that at least a portion of the spiked naps grip at least a portion of the pores of the grip-type knit mesh to hold the three-dimensional structure of the surgical implant.
