Title:
ARTIFICIAL HEART VALVE
Document Type and Number:
WIPO Patent Application WO/2018/184225
Kind Code:
A1
Abstract:
An artificial heart valve, comprising: an annular frame (2), the frame (2) being a mesh structure which may radially expand and be deformed; a plurality of U-shaped protruding portions (1) are arranged on the frame (2) at an end which is downstream along the direction of blood flow; U-shaped recessive portions (3) are formed between the protruding portions (1), and one or more bends (a, b) are provided on a side of a recessive portion (3). When the artificial heart valve is expanded for the first time, the protruding portions (1) and the recessive portions (3) are unfolded, and the bends (a, b) are unfolded when the artificial heart valve is expanded again. The artificial heart valve solves the technical problem wherein existing heart valves are fixed in size after being implanted into the human body and may not adapt to the growth of a patient.
