Special model-fitting modularized occluder for promoting thrombosis of pseudocoele of aortic dissection

Abstract

The invention discloses a special model-fitting modularized occluder for promoting thrombosis of a pseudocoele of an aortic dissection. The special model-fitting modularized occluder is of a three-piece structure. The special model-fitting modularized occluder comprises a dissection pseudocoele proximal end occluding member, a pseudocoele middle occluding member and a pseudocoele distal end occluding member, wherein combinations of different components are selectively applied and combined and used in service according to breaks of different types of a distal end of the aortic dissection. The invention provides the special model-fitting modularized surface-modified coagulant occluder for clinics, the occluder can be applicable to pseudocoele of various shape characteristics, the thrombosisand reconstruction of the pseudocoele are effectively promoted, and the application is extensive; and an appropriate model can be selected according to the shape and size of the pseudocoele, so that the economic burden is alleviated, and the surgical operation time is shortened. Simultaneously, a special release system is designed to achieve accurate release and reduce injury to the pseudocoele, so that the aims of better promoting the thrombosis action of the pseudocoele, improving forward treatment effect on the pseudocoele and improving global prognosis of the dissection are achieved.

Description

technical field [0001] The invention relates to a conformable and modular special occluder for promoting thrombosis of aortic dissection false lumen. Background technique [0002] After endovascular repair of aortic dissection, some patients experience repeated low back pain or continuous expansion of the distal aorta, which is caused by the continuous blood flow of the false lumen, and the false lumen is completely repaired so that the false lumen no longer has blood perfusion In order to reduce the risk of rupture, choose a better false lumen filler, better repair the distal tear and promote complete thrombosis of the false lumen are our goals. [0003] At present, there are various treatment methods for the false lumen of aortic dissection, but the advantages and disadvantages are also obvious: for example, the implantation of bare stents can promote the reconstruction of the true lumen of the aorta to ensure the distal blood supply and compress the distal false lumen.

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing aortic dissection false lumen occluder cannot be applied to false lumens with various characteristics at the same time, and the application is relatively limited.
