Prosthetic heart valve system

Abstract

A prosthetic heart valve system is provided. The artificial heart valve system comprises a valve part and a conveying system part, the valve part comprises a valve frame, valve leaflets and a sealing skirt, the valve frame comprises an atrial part, a ventricular part (18), an anchoring part (19) and a first connecting piece (20), the anchoring part (19) is connected with the first connecting piece (20), the anchoring part (19) extends towards the atrial part, and the first connecting piece (20) is provided with an abutting section (25). The conveying system part is provided with a fixing part used for containing the abutting section of the valve frame. According to the heart valve prosthesis system, clamping and anchoring of the heart valve prosthesis system after the heart valve prosthesis system is implanted into the human body can be improved, and the surgical operation difficulty and complications after the heart valve prosthesis system is implanted can be reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and particularly relates to an artificial heart valve system. Background technique [0002] Valve disease is a common heart valve disease, and the incidence increases with age. For diseased valves, surgery is usually used to replace the artificial heart valve system, but some patients cannot accept surgery due to their age and other reasons. For such patients, interventional valves can be used because they do not require thoracotomy, with less trauma and recovery. The advantages of fast speed have received more and more extensive attention and attention. [0003] Interventional aortic valves have made good progress over the last two decades and are now the standard of care for patients who are inoperable or at high risk for surgery. However, the mitral valve and tricuspid valve, which are atrioventricular valves, are complicated by the anatomical structure of the valve position. After t...

AI Technical Summary

Problems solved by technology

The barb method achieves positioning by hooking the valve leaflet, which is relatively firm and causes less damage to the heart; however, the complexity of the subvalvular structure makes the release control of the barb structure cumbersome, and the design of the anchoring barb is difficult during the release process. The valgus expansion is limited, and it is not easy to grasp the valve leaflets. The cumbersome and repeated operations of grasping the cards increase the difficulty of the operation and increase the risk of valve anchoring failure

After the valve is implanted in the human body, it will not be stuck firmly or loosen, which will lead to serious postoperative complications
