  • Publication number: 20210228347
    Abstract: A transcatheter, percutaneously implantable, prosthetic heart valve is provided that comprises a lattice frame and two or more integrated cusp and leaflet folded structures attached to the lattice frame. The two or more integrated cusp and leaflet folded structures each comprise a flat sheet of biocompatible membrane that is folded to include a substantially conical shape according to a flat folding pattern. The substantially conical shape is further formed by joining apposing sides of the substantially conical shape along a seam. The two or more integrated cusp and leaflet folded structures are each attached along their respective seams to the lattice frame in a direction substantially parallel to an axis of the lattice frame. Embodiments of valves described herein have application within the entire vascular system.

  • Publication number: 20210016098
    Abstract: A pessary for the prevention of preterm birth, and in particular two pathological conditions of pregnancy known as isthmico-cervical incontinence and cervical shortening, both of which are associated with increased risks for pregnancy loss and/or premature deliveries of babies. The pessary includes a sleeve supported within a ring by an annular member. The sleeve is intended to contact the cervix and maximize the length of the cervix while the annular member and ring contact the vagina. The pessary may be fabricated from a pliable medical-grade silicon, and the pessary may include one or more sensors to measure various patient parameters indicative of a premature cervical contraction. The sleeve may be wirelessly powered from a charging device, such as a pillow, a table-top device, or a pelvic belt.

  • Patent number: 10390945
    Abstract: A method of making a replacement heart valve device whereby a fragment of biocompatible tissue material is treated and soaked in one or more alcohol solutions and a solution of glutaraldehyde. The dried biocompatible tissue material is folded and rehydrated in such a way that forms a two- or three-leaflet/cusp valve without affixing of separate cusps or leaflets or cutting slits into the biocompatible tissue material to form the cusps or leaflets. After the biocompatible tissue material is folded, it is affixed at one or more points on the outer surface to the inner cavity or a stent.

  • Publication number: 20190159897
    Abstract: An assembly configured for replacing an aortic or pulmonary heart valve in a human patient includes a transcatheter, prosthetic aortic or pulmonary heart valve. The transcatheter, prosthetic hear valve includes a frame that is expandable and collapsible, a tissue leaflet assembly sutured directly to the frame. The assembly also includes a percutaneously insertable valve delivery mechanism, wherein the transcatheter, prosthetic heart valve is releasably and coaxially mounted onto a balloon catheter of the percutaneously insertable valve delivery mechanism. The balloon catheter includes a guidewire lumen. The transcatheter, prosthetic heart valve releasably and coaxially mounted onto the balloon catheter are included in a sterile packaging to form the assembly.
