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).
