Abstract

The invention provides an implant conveying device and an implant conveying system. The implant conveying device comprises a conveying assembly, a first control bending pipe and a second control bending pipe. At least one part of the conveying assembly movably penetrates through the first control bending pipe in the axial direction of the first control bending pipe. The first control bending pipe and the conveying assembly movably penetrate through the second control bending pipe in the axial direction of the second control bending pipe and are used for extending out of the far end of the second control bending pipe; the first bending control pipe and the second bending control pipe are configured to control bending respectively; and the extension direction of the conveying assembly is changed along with the bending shapes of the first control bending pipe and the second control bending pipe. By means of the configuration, bending control is conducted on the bending control pipe in a segmented mode, large-angle bending control can be achieved, and the problems that an existing conveying device is difficult to control bending and small in bending control angle are solved. The implant can be safely and accurately released in a narrow space, and the problems of perivalvular leakage and the like in the operation process are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an implant delivery device and an implant delivery system. Background technique [0002] Heart valves are membrane-like structures that can open and close in the organs of humans or certain animals. Every human heart has four valves. The aortic valve connects the left ventricle to the aorta, the pulmonary valve connects the right ventricle to the pulmonary artery, the mitral valve connects the left atrium to the left ventricle, and the tricuspid valve connects the right atrium to the right ventricle. They all act as one-way valves, so that blood can only flow from one direction to the other and not back. [0003] With the development of social economy and the aging of the population, the incidence of valvular heart disease has increased significantly. Studies have shown that the incidence of valvular heart disease in the elderly population over 75 years old is as high a...
