Novel multifunctional cardiovascular medical coronary stent

Abstract

The invention discloses a novel multifunctional cardiovascular medical coronary stent which comprises a first main component. The first main component comprises a plurality of first wave crests and aplurality of first wave troughs, the left sides of the first wave troughs are fixedly connected with the left ends of first connecting pieces, the right ends of the first connecting pieces are fixedlyconnected with the left ends of first connecting rods, and the first connecting rods are fixedly connected with the left side surfaces of second wave troughs of a second main component. The novel multifunctional cardiovascular medical coronary stent has the advantages that the first component, the second component and a third component are matched with one another, are made of cobalt-chromium alloy and are high in corrosion resistance and acid resistance, vascular membranes can quickly cover the novel multifunctional cardiovascular medical coronary stent, and accordingly the novel multifunctional cardiovascular medical coronary stent and blood vessels can be integrally fused with one another; the novel multifunctional cardiovascular medical coronary stent is an extensible reticulated hollowed-out tubular body, accordingly, effective support effects can be realized by the novel multifunctional cardiovascular medical coronary stent, and blood can be stably circulated in the blood vessels.

Description

technical field [0001] The invention relates to the technical field of coronary stents, in particular to a novel multifunctional coronary stent for cardiovascular medicine. Background technique [0002] Coronary stent The right vascular stent refers to the placement of an internal stent in the diseased segment on the basis of luminal balloon expansion to support the stenotic and occluded segment of the vessel, reduce the elastic retraction and reshaping of the vessel, and maintain the blood pressure in the cavity. purpose of smooth flow. Some internal stents can also prevent restenosis. [0003] Most of the existing coronary stents are carved and processed from metal pipes. The metal coverage of coronary stents is relatively large. Although the radial support force is improved, the flexibility and delivery type of the stents are poor, and the metal coverage rate is relatively high. Although reducing the stent can improve the flexibility of the stent, there are insufficient...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of multifunctional coronary stent for cardiovascular medicine, which solves the problem that the metal coverage of the coronary stent is relatively large. Although the radial support force is improved, the flexibility of the stent And the delivery type is poor, and the reduction of the metal coverage can improve the flexibility of the stent, but its support force and expansibility are insufficient, which is not conducive to the treatment of branch vessels.
