  • Patent number: 11547558
    Abstract: A heart valve prosthesis anchored to an interventricular septum. The heart valve prosthesis includes a valve supporting frame and a fixing device. The valve supporting frame includes a valve stitching section and an artificial valve. The artificial valve is fixedly connected to the valve stitching section. The fixing device includes a fixing and supporting section and a fixing member. One end of the fixing and supporting section is connected to a proximal end of the valve stitching section, and another end of the fixing and supporting section is connected to the interventricular septum of a patient by the fixing member, to support the heart valve prosthesis and prevent the heart valve prosthesis from axially moving.

  • Patent number: 10398547
    Abstract: An implant with anchoring device for heart valve disease comprises a cardiac valve prosthesis (1), at least two sets of anchoring needles (2) and at least two sets of anchoring needle releasing devices (3). Proximal end of the anchoring needles (2) are provided with anti-disengagement ends (23). The anchoring needle releasing devices (3) are detachably connected to the cardiac valve prosthesis (1). The anchoring needle releasing devices (3) comprise delivery tubes (31) and shafts (32). Distal sections of the anchoring needle releasing devices (3) are in preset shapes. The shafts (32) can be pushed to force the anchoring needles (2) to move toward the distal ends of the delivery tubes (31), so that the cardiac valve prosthesis (1) is fixed between autogenous tissue (6) and the anti-disengagement ends (23) to achieve accurate positioning and firm anchoring of the cardiac valve prosthesis (1).
