Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an interventional transapical artificial heart valve delivery system. The interventional transapical artificial heart valve delivery system comprises a conveying mechanism and a catheter sheath mechanism, wherein the conveying mechanism comprises an outer tube, an inner tube and a handle assembly, thehandle assembly is connected with the outer tube, one end of the inner tube is mounted on the outer tube, and the inner tube moves in the axial direction of the outer tube. An artificial heart valve is loaded on the outer tube and is clamped and matched with the inner tube. The catheter sheath mechanism is connected with the outer tube and used for conducting transapical access on the conveying mechanism so as to achieve conveying of the artificial heart valve. According to the artificial heart valve delivery system, minimally invasive interventional transcatheter artificial heart valve is adopted, the replacement operation wound is small, the postoperative recovery period is short, operation is easy and rapid, and the success rate is high.

Description

technical field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an interventional transapical artificial heart valve delivery system. Background technique

[0002] The human heart is divided into left and right parts and has four chambers, namely left and right atrium and left and right ventricle. The inlet and outlet of the left and right ventricle have heart valves respectively, which control the flow of blood, prevent the backflow of blood, and play the role of a one-way valve. The valves on the left side of the heart, the mitral and aortic valves, experience relatively greater stress during the cardiac cycle, and valvular disease of the aortic and mitral valves is also the most common heart valve disease.

[0003] An effective treatment for valve disease is valve replacement. In conventional surgical thoracotomy for valve replacement, the heart must be stopped, extracorporeal circulation established, and the heart be...
