AI Technical Summary

Technical Problem

The prior art is difficult to effectively solve the problems of heart failure and pulmonary edema caused by mitral valve lesions, especially in elderly patients with high risk of surgery.

Method used

An artificial valve device combining the leaflet and the membrane body is designed with a valve frame including a main body frame segment, an upper crown frame segment and an anchor frame segment. The valve frame can be stably positioned in the left atrium and left ventricle through the hollow structure and the design of the anchoring frame to prevent outflow tract obstruction.

Benefits of technology

This device can effectively replace the native mitral valve, prevent blood reflux, reduce the risk of pulmonary edema, and reduce complications during surgery. It is suitable for patients with high surgical risks.

Abstract

The invention relates to a valve frame and an artificial valve device. A main frame inner space is formed in a main frame section, the main frame section is provided with a far-end opening, the main frame section is provided with a near-end opening, an upper crown frame section is connected with the far end of the main frame section, the upper crown frame section is an annular frame body, and a crown frame inner space is formed in the upper crown frame section; the inner space of the crown frame is communicated with the inner space of the main frame through the far-end opening, the anchoring frame section is connected with the near end of the main frame section, and the axial length of the anchoring frame section is larger than that of the main frame section. The anchoring frame section is in an axial slender structural form in the overall structure of the valve frame, compared with the anchoring frame section, the axial length of the main body frame section is short, the main body frame section can be relatively upward and close to the upper side of an original valve ring after the valve frame is implanted into a left atrium and a left ventricle, and meanwhile the hollow structure design on the main body frame section is adopted, so that the structure of the main body frame section is more compact. And the position of the hollow structure on the main body frame section corresponds to the position of the sewed bovine pericardium, so that the risk that the outflow tract of the left ventricle is obstructed can be effectively prevented.
