Problems solved by technology

However, this docking coil includes an atrial segment coil and a ventricular segment coil, and the junction of the atrial segment coil and the ventricular segment coil passes through the native valve annulus, thereby creating a risk of paravalvular leak at the native valve annulus
In addition, because the release process of the docking coil is relatively complicated, and the positioning of the docking coil is relatively high, this will increase the difficulty of the artificial heart valve implantation operation, and has high requirements for the operator's proficiency in operation. Operating time also adversely affects the health of the patient

Embodiment 3

[0065] For the sake of clarity, the anchoring device 300 of the third embodiment uses different labels from the anchoring device 100 of the first embodiment, but even if the labels are different, for the same parts, the embodiment of the anchoring device 100 of the first embodiment is also applicable The anchoring device 300 in the third embodiment. The following mainly describes only the differences from the first embodiment, and for the same parts, please refer to the first embodiment.

[0066] see Figure 4As shown, a preferred embodiment of the present invention provides an anchoring device 300 for an artificial heart valve. The anchoring device 300 includes an anchoring section 310 and a supporting section 320 that are axially interconnected. The cavity 311, the support section 320 is arranged on one side of the anchor section 310 along the axial direction, the support section 320 includes at least two elastic wires 321 arranged in sequence along the circumferential dire...

Abstract

The invention provides an anchoring device of a heart valve prosthesis and a heart valve prosthesis system.The heart valve prosthesis system comprises the anchoring device and the heart valve prosthesis, the anchoring device comprises an anchoring section and a supporting section which are axially connected with each other, and the anchoring section is provided with an annular first cavity capable of containing the heart valve prosthesis; the supporting section is arranged on one side of the anchoring section in the axial direction, the supporting section comprises at least two elastic wires which are sequentially arranged in the circumferential direction of the anchoring section, one end of each elastic wire is connected with the anchoring section, and the other end of each elastic wire extends in the direction away from the anchoring section. According to the anchoring device, anchoring of the heart valve prosthesis can be achieved through the structure of the preset cavity, the anchoring device does not need to cross an original valve ring in the implanting process, and then perivalvular leakage can be effectively prevented after the heart valve prosthesis is implanted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anchoring device for an artificial heart valve and an artificial heart valve system. Background technique [0002] Transcatheter mitral valve replacement (TMVR for short) is a method of catheter intervention. After the artificial heart valve is compressed into the delivery system in vitro, it is delivered to the human mitral valve annulus along the vascular path or through the heart apex, and the artificial heart valve is compressed. The prosthetic heart valve is released and fixed at the mitral valve annulus to replace the native valve. Compared with surgical operations, mitral valve replacement surgery does not require extracorporeal circulation auxiliary devices, with less trauma and quicker recovery of the patient. Postoperative hemodynamic indicators can be significantly improved. Compared with the apical approach, the trans-femoral septal approach is used for imp...
