  • Publication number: 20210228385
    Abstract: A prosthetic vascular valve includes one or more continuous loops of frame material or one or more strands of material that do not form a continuous loop. The frame includes a plurality of longitudinal portions, wherein a membrane is attached to at least one of the longitudinal portions, and wherein the membrane is configured to open and close. During implantation, the frame engages the inner surface of the vein wall and is biased against the vein wall to remain stationary. In use, blood flows from an upstream end to a downstream end, wherein the membrane mitigates regurgitation of the blood as the blood is conveyed through the subject vein.

  • 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.

  • 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.

  • Publication number: 20190076233
    Abstract: A sealing device for use as a vascular implant including a frame, the frame having an inflow edge and an outflow edge relative to axial blood flow within a vessel, wherein at least a partial axial extent of the frame is configured to decrease in axial length when expanded from a radially compressed configuration to a radially expanded configuration. The sealing device also includes a membrane layer coupled to a radially outward surface of the at least partial axial extent of the frame between the inflow edge and the outflow edge of the frame, wherein the membrane layer is coupled to the frame at one or more axially spaced connection points such that at least a portion of the membrane layer projects radially outward relative to the frame when the frame is in the radially-expanded configuration.

  • Patent number: 9119738
    Abstract: A dual-balloon delivery catheter system includes a carrier segment that is a lead/carrier balloon or mandrel at a distal portion of a catheter. The carrier segment is sequentially arrayed with a more proximally positioned delivery segment, wherein the delivery segment is a delivery balloon or mandrel. The first carrier segment expands the stent-valve a sufficient amount to receive the delivery segment after the carrier segment is moved away from the sent-valve. The delivery segment is then positioned at the target site and the stent-valve is then deployed.
