A conformable modular occluder for promoting false lumen thrombosis in aortic dissection

Abstract

The invention discloses a conformable and modular special occluder for promoting thrombosis of aortic dissection and false lumen, which is a three-piece structure, including a proximal part of the dissection false lumen, a middle part of the false lumen and a distal part of the false lumen. According to the different types of breaches at the distal end of the aortic dissection, the end-blocker is selectively combined with different parts and put into practical use. The present invention provides a conformable and modular special-purpose surface-modified and coagulation-promoting false lumen occluder for clinical use, which can be suitable for false lumens with various shapes and characteristics, effectively promotes the formation and reconstruction of false lumen thrombus, and is widely used ; The appropriate model can be selected according to the shape and size of the false cavity to reduce the economic burden and shorten the operation time. At the same time, a special release system is designed to accurately release and reduce damage to the false lumen, so as to better promote the thrombosis of the false lumen, improve the long-term therapeutic effect of the false lumen, and improve the overall prognosis of the dissection.

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.
