Embodiment Construction

[0037] As described in the background art, the present invention provides a heart valve prosthesis and its stent for the problem that the interventional valve prosthesis currently on the market cannot be applied to a variety of valves and requires multiple sets of delivery systems and multiple implantation treatments.

[0038] After further research, in one embodiment, a stent for a heart valve prosthesis is provided. The stent is used to support an artificial heart valve, wherein the stent includes an inflow channel, an outflow channel, and an inflow channel and an outflow channel along the axial direction. The transition area between the outflow channels; the stent has a contracted configuration and an expanded configuration; the outflow channel includes a ring structure and at least two protruding structures extending along the axial direction; the at least two protruding structures are respectively connected to the ring structure The ends away from the transition region are...

Abstract

The invention relates to a cardiac valve prosthesis and a bracket thereof. The bracket comprises an inflow tract, an outflow tract and a transitional region located between the inflow tract and the outflow tract in the axis direction, wherein the outflow tract comprises a ring structure and at least two evagination structures formed through extending in the axis direction; the at least two evagination structures are respectively connected with one end away from the transitional region, of the ring structure; and a vacant region is restricted between every two adjacent evagination structures. The cardiac valve prosthesis and the bracket thereof disclosed by the invention can be suitable for various valve replacement surgeries at the same time, damage risk of the surgeries on patients and the surgery cost can be reduced, and the influence of the bracket on the cardiac function can be minimized.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a heart valve prosthesis and a bracket thereof. Background technique [0002] The heart has four chambers, the left atrium and left ventricle are on the left side of the heart, and the right atrium and right ventricle are on the right side of the heart. The atrium and ventricle form the ventricular inflow tract, the left ventricle and the aorta form the left ventricular outflow tract, and the right ventricle and the pulmonary artery form the right ventricular outflow tract. There are valves with the function of "one-way valve" at the ventricular inflow and ventricular outflow to ensure the normal flow of blood in the heart chamber. When there is a problem with this valve, the hemodynamics of the heart are altered and the heart functions abnormally, which is called valvular heart disease. [0003] With the development of social economy and the aging of the population...
