  • Patent number: 11554017
    Abstract: Dislodgment of a constricting cord from an annulus can be prevented by delivering the distal loop portion of the constricting cord to the annulus using a percutaneous delivery tool, and launching anchors into the annulus so as to affix the distal loop portion of the constricting cord to the annulus. The percutaneous delivery tool is withdrawn in a proximal direction after the anchors have been launched. A pushing member is pressed in a distal direction so that the pushing member holds a portion of the constricting cord against the annulus with enough pressure to prevent dislodgment of any of the anchors during the withdrawal of the percutaneous delivery tool.

  • Publication number: 20120316642
    Abstract: An invasive cardiac valve comprises a tubular stent (1) and a valve (2). One end of the tubular stent (1) is of a frusto-conical structure, the other end is wide open, and the diameter of the open end is greater than the diameter of the frusto-conical end. The valve (2) is attached to the frusto-conical end of the tubular stent (1); and a delivery and retrieval hole (4) of the cardiac valve is provided at the top of the open end of the tubular stent (1). Because the diameter of the open end is greater than the diameter of the frusto-conical end, the cardiac valve can be effectively fixed in a position of aortic annulus to prevent the cardiac valve displacement caused by the impact of the blood flow. Because the valve (2) is attached to the frusto-conical end of the tubular stent (1), the valve (2) can totally avoid the left and right coronary ostia and does not affect the haemodynamics of the coronary artery.

  • Patent number: 8323337
    Abstract: A heart valve assembly includes a prosthesis and a prosthetic valve to replace a preexisting natural or prosthetic heart valve within a biological annulus. The prosthesis includes an annular member, a flexible core at least partially defining a sewing cuff extending radially outwardly from the annular member, a rail ring disposed between the flexible core and the annular member, and a plurality of guide rails extending from the rail ring through respective openings in the flexible core. A fabric covering covers the prosthesis, and the guide rails extend through respective openings in the fabric covering. The prosthetic valve includes a frame including receptacles for receiving respective guide rails. After implanting the prosthesis within a biological annulus, the prosthetic valve is advanced along the guide rails until retention elements on the guide rails engage the receptacles to secure the prosthetic valve relative to the prosthesis.

  • Publication number: 20120226348
    Abstract: A heart valve assembly includes an annular prosthesis and a valve prosthesis. The annular prosthesis includes an annular ring for dilating tissue within a biological annulus and a conformable sewing cuff extending radially from the annular member. The valve prosthesis includes a frame and a valve component. The annular ring is introduced into the biological annulus to dilate tissue surrounding the biological annulus and the sewing cuff conforms to tissue above the biological annulus. Fasteners are directed through the sewing cuff to secure the annular prosthesis to the biological annulus. The annular prosthesis may include a baleen element for biasing fabric on the annular ring outwardly to enhance sealing against the biological annulus. A valve prosthesis is then advanced into the sinus cavity, and secured relative to the annular prosthesis. The sewing cuff may enhance a seal between the valve prosthesis and annular prosthesis.

  • Patent number: 8105377
    Abstract: A fixation band has a tubular frame and a tube, wherein the tubular frame comprises longitudinally-extending members having a hook on its distal end and fixation means on its proximal end. The tubular frame preferably comprises a laterally-extending member for stabilization. The tube is positioned inside longitudinally-extending members and a sewing cuff is formed in the tube distal to the distalmost end of the longitudinally-extending members. A standard prosthetic valve can be secured to the fixation band by suturing the prosthetic valve's sewing cuff to the fixation band's sewing cuff and the prosthetic valve can be advanced to a valve seat. By pulling the tubular frame proximally, the hooks pass into surrounding tissue so that the fixation band and prosthetic valve are fixed against proximal movement. The fixation means then secure the fixation band to the surrounding tissue so that the prosthetic valve is fixed against distal movement.

  • Publication number: 20110301699
    Abstract: Apparatus and methods are provided for thermally and/or mechanically treating tissue, such as valvular structures, to reconfigure or shrink the tissue in a controlled manner. Mechanical clips are implanted over the leaflets of a valve, e.g., in the heart, either alone or after thermal treatment to cause the valve to close more tightly. The clips are delivered by a catheter and may be configured to traverse directly over the valve itself or to lie partially over the periphery of the valve to prevent obstruction of the valve channel. The clips can be coated with drugs or a radiopaque coating. Alternatively, individual anchors with a tensioning element, like a suture, may be used to approximate the valves towards each other. The catheter can also incorporate sensors or energy delivery devices, e.g., transducers, on its distal end.

  • Patent number: 7993393
    Abstract: A highly flexible tissue-type heart valve is disclosed having a structural stent in a generally cylindrical configuration with cusps and commissures that are permitted to move radially. The stent commissures are constructed so that the cusps are pivotably or flexibly coupled together at the commissures to permit relative movement therebetween. The stent may be cloth-covered and may be a single element or may be made in three separate elements for a three cusp valve, each element having a cusp portion and two commissure portions; adjacent commissure portions for each pair of adjacent stent element combining to form the stent commissures. If the stent has separate elements their commissure portions may be pivotably or flexible coupled, or may be designed to completely separate into independent leaflets at bioresorbable couples. The cloth covering may have an outwardly projecting flap that mates with valve leaflets (e.g., pericardial leaflets) along the cusps and commissures.

  • Patent number: 7927369
    Abstract: An intraparietal reinforcing device is designed to be integrated into a biological valvular prosthesis consisting of a biological cardiac valve having a valve plane formed by leaflets attached laterally to an external wall along commissurae. The device can be placed in the organic tissue of the valve, and includes a base and a stabilizing part mounted thereon. The device can be inserted inside the external wall of the valve to reinforce the valve's structure and to maintain the valve's shape after implantation. The stabilizing part includes at least two intraparietal shafts, designed to be inserted into the valve tissue and positioned on the base so that, once the device is put in place on the valve, they are displaced laterally to the intersection point of the intersection line of the external wall with the commissurae and of the valve plane. A biological prosthesis may be provided with such a device.
