Abstract

The invention relates to an aorta biovalve with a compressible suture edge, which belongs to the field of passive medical instruments in the cardiovascular surgery field. The valve comprises a valve stent and a valve leaflet, wherein the valve stent comprises an inflow end, a middle section and an outflow end; the inflow end is composed of a compressible base ring, a polymer layer wrapping the base ring and a polymer sewing edge wrapping the polymer layer, the middle section is composed of a straight supporting rod and an arc-shaped positioning rod protruding outwards, one end of the supporting rod and one end of the positioning rod are fixed to the compressible base ring, and the other end of the supporting rod and the other end of the positioning rod are connected with the outflow end. The outflow end is of a horn-mouth-shaped grid structure; the valve leaflets are located in the middle section of the valve stent and fixed to the supporting rod and the base ring, and three or more parts capable of being movably opened and closed are formed. The valve can be implanted into the position of an in-situ aortic valve with aortic membrane stenosis and aortic insufficiency lesion, and has the characteristics of wide application range, accurate positioning, tight fitting, small comprehensive damage and long valve durability.

Description

technical field [0001] The invention relates to an aortic biological valve with a compressible suturing edge, which is used for surgical replacement of an aortic valve with incomplete regurgitation, and belongs to the passive medical device in the field of cardiovascular surgery. [0002] technical background [0003] Heart valve disease is still a common major heart disease, including aortic stenosis and regurgitation. With the improvement of people's living standards in our country and the development of population aging, there are more and more patients with aortic valve disease. The related artificial heart The demand for valves is also increasing, and heart valve replacement operations currently account for nearly one-third of the total number of heart surgeries. However, these surgically implanted valves all include a rigid annular base, whose specifications and sizes are often different from the patient's annulus, making it difficult to fit accurately and prone to para...
