Abstract

The invention provides a valve stent and an interventional mitral valve replacement system comprising the same. The valve stent comprises a metal frame, and a supporting ring is arranged at the edge of one end of the metal frame along the outer edge in the circumferential direction; the metal frame is formed in a surrounding mode by a curved surface straight wall and a plane straight wall so as to form a D-shaped straight cylindrical structure; two strands of connecting wires are respectively arranged at the two ends of the metal frame; the two strands of connecting wires are respectively used for connecting the edge of the curved surface straight wall and the edge of the plane straight wall at the two ends of the metal frame; and the two strands of connecting wires at each end intersect in an X shape to cut interfaces at the two ends of the metal frame into an 8 shape. The valve stent is used for supporting, fixing and sealing a subsequent interventional mitral valve.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a valve support and an interventional mitral valve replacement system including the same. Background technique [0002] Mitral regurgitation (Mitral Regurgitation), as a common heart valve disease, can be divided into mild, moderate, moderately severe and severe according to the degree of disease. The incidence of moderate MR in the population is 1.7%, and with age, it can approach 10% in the population >74 years old. At present, most of the treatment methods for patients with mitral valve regurgitation use interventional mitral valve treatment techniques, which are usually divided into two methods: repair and replacement. However, when the mitral valve repair method is not enough to achieve the therapeutic effect, mitral valve replacement is still required. At this time, the patient's own conditions are usually unable to perform surgery again, so transcat...
