摘要： Vascular filtering devices and methods for their use are disclosed. In some embodiments, the vascular filtering devices include an elongate member having an unsupported membrane bag portion attached thereto. The membrane may be porous in some examples. Multiple elongate extensions may also extend from the membrane, and may extend along the elongate member, such as to a proximal region of the elongate member. The unsupported membrane bag portion may be configured to inflate or otherwise radially expand away from the elongate member as a result of blood flowing through the vessel within which the vascular filtering device is positioned.

摘要： The present embodiments provide a medical device for implantation in a patient comprising a stent and a valve. The stent comprises a proximal region comprising a cylindrical shape having a first outer diameter in an expanded state, and a distal region comprising a cylindrical shape having a second outer diameter in the expanded state. The second outer diameter is greater than the first outer diameter. A proximal region of the valve is at least partially positioned within the proximal region of the stent, and the distal region of the valve is at least partially positioned within one of tapered and distal regions of the stent. When implanted, the proximal region of the stent and the proximal region of the valve are aligned with a native valve, and the distal region of the valve is distally spaced-apart from the native valve.

摘要： A method of implanting a prosthetic apparatus preferably includes delivering the prosthetic apparatus to a native mitral valve and exposing ventricular anchors and a spacer body of the prosthetic apparatus from a distal end portion of a delivery apparatus. The ventricular anchors are controllably and forcibly expanded outwardly from the spacer body to an expanded configuration. The prosthetic apparatus is positioned relative to the native mitral valve such that native mitral valve leaflets are located between the ventricular anchors and the spacer body. The ventricular anchors are then contracted radially inwardly toward the spacer body to a compressed configuration. In the compressed configuration, the native mitral valve leaflets are secured between the ventricular anchors and the spacer body. After implantation, the spacer body is held between the native mitral valve leaflets, thereby blocking regurgitation and improving the function of the native mitral valve.

摘要： Delivery systems for expandable and stented implants include adjustable tensioning members that control the expansion of the implant along the length of the implant. The tensioning members are wound onto one or more rotors located on the distal segment of the delivery system, which are rotated to unwind the tensioning members and incrementally expand the implant. Positioning mechanisms are also provided to adjust the position and orientation of the implant during delivery.

摘要： A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.

摘要： The techniques of this disclosure generally relate to a valve prosthesis having a prosthetic valve, a stent structure, and anti-migration spikes. The stent structure is coupled to the prosthetic valve and includes an inflow portion. The anti-migration spikes are attached to the inflow portion, the anti-migration spikes protruding radially outward and in an outflow direction from the inflow portion. The anti-migration spikes penetrate into tissue of the vessel, e.g., the aortic annulus of a patient's left ventricle, to prevent migration, i.e., undesirable movement, of the valve prosthesis within the vessel after deployment.

摘要： The present invention comprises a novel and safer mechanism of deployment using a self-positioning, self-centering, and self-anchoring method. To embody the present invention, a disk-based valve apparatus allowing the repositioning and retrieval of the implantable valve while working on a dysfunctional valve structure is disclosed. The disk-based valve apparatus may comprise one or more disks, either proximal or distal, a valve-housing component and a valve component. The one or more disks may be either proximal or distal, may be either connected to each other or disconnected from each other and may either be symmetrical or have different shapes and dimensions. The disk-based valve apparatus may be self anchoring, such as anchored by pressure from the one or more disk, or may be anchored using any anchoring.

摘要： A heart valve repair system includes a delivery sheath and an implant that includes a frame having a surface configured to contact an upstream surface of a native heart valve. First and second gripping members are coupled to the frame and each (1) includes first and second arms and (2) is configured to clamp a respective native leaflet. The implant is disposed in the sheath in a delivery state in which the frame defines a wall fully surrounding a central longitudinal axis of the implant. The distal end of the wall defines a distal opening of the frame. The distal end of the wall is disposed proximally to the entire first tissue-engaging surface of each of the gripping members and proximally to the entire second tissue-engaging surface of each of the gripping members. Other embodiments are also described.
