Abstract

The invention relates to a surgical assembly capable of preventing endoleak and provided with a spring coil and a chimney stent. A first support frame is arranged in a main body stent; a first film wraps the first support frame; the main body stent is of a round structure, and a groove for wrapping the chimney stent is defined after the side face of the main body stent is pressed; first artificialfibers are arranged on the part, making contact with the chimney stent, of the groove; a second support frame is arranged in the chimney stent, and a second film wraps the second support frame; second artificial fibers are arranged in the longitudinal direction of the spring coil; the spring coil is wound around the chimney stent; and the chimney stent and the spring coil are implanted into the groove of the main body stent via a stent implanting device. According to the surgical assembly provided by the invention, endoleak can be effectively prevented, complete closure of graft pathologicalarteries can be achieved and the occurrence of complications can be reduced.

Description

technical field [0001] The invention relates to the technical field of arterial stents, in particular to an anti-endoleak and coiled chimney stent surgical assembly that effectively prevents endoleaks, realizes complete closure of diseased arteries of grafts, and reduces complications. Background technique [0002] Aortic dilated lesions often involve important visceral branch vessels, so whether traditional open surgery or endovascular exclusion is adopted, it is extremely challenging. For complex lesions, the process of endoluminal graft implantation may obstruct the blood flow of branch vessels and cause serious complications. Chimney repair ensures perfusion of branch arteries inadvertently covered by endoluminal grafts. Chimney repair refers to releasing the stent graft side by side between the covered branch vessel and the aorta when the important branch opening needs to be intentionally covered or inadvertently closed due to insufficient anchoring area during the pla...
