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.
