A device for implantation in the vasculature of a patient includes a first frame segment and a second frame segment. The first frame segment includes a first frame and a first membrane attached to the first frame. The second frame segment is linked by a linkage to the first frame segment. The second frame segment includes a second frame and a second membrane attached to the second frame.

Prosthetic vascular valves having linked frame segments

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.

Conduit vascular implant sealing device for reducing endoleaks

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.

Prosthetic vascular valve and methods associated therewith

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.

Percutaneously deliverable heart valve including folded membrane cusps with integral leaflets

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.

Percutaneously implantable replacement heart valve device and method of making same

Percutaneous prosthetic heart valve

Percutaneous replacement heart valve and a delivery and implantation system

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.

Method and apparatus for the endoluminal delivery of intravascular devices

Method of controlled release of a percutaneous replacement heart valve

A prosthetic heart valve implantable by catheter without surgery includes a substantially 'dry' membrane or tissue material. In at least one embodiment, the tissue is folded in a dry state to form a tissue leaflet assembly that is then attached to a frame to form an implantable prosthetic heart valve. Alternatively, one or more tissue leaflets are operatively associated with a frame to form an implantable prosthetic heart valve. The implantable prosthetic heart valve is subsequently pre-mounted on an integrated catheter delivery system. The catheter delivery system that includes the implantable prosthetic heart valve is then packaged and transported while the tissue remains dry. The implantable prosthetic heart valve, while remaining substantially dry, can then be implanted into the receiving patient.
