(57)< Abstract > Disposal of the aneurysm, the movements pulse deformity with high flow fistula (AVM) being the new composition in order the plug to form the blood vessel which especially is suitable for disposal, and the plug formation of the blood vessel, (a) the organism compatibility polymer (B) organism compatibility contrast medium Although and (the organism compatibility solvent which solubilizes c) aforementioned organism compatibility polymer is included, here, the polymer deposit which the blood vessel region the plug is done is formed the occasion where it transports to the blood vessel region, making use of the aforementioned polymer of ten quantity, at the same time, the composition which features that at least it possesses the viscosity of approximately 150cSt with the 40C is offered. In addition, (a) the transport device which provides the ejection port for the blood vessel region where the mammal is selected is arranged (B) it possesses the viscosity of approximately 150cSt at least with the 40C, the organism compatibility polymer, the organism compatibility solvent and the composition which includes the contrast medium optionally, through the ejection port of the transport device, the fact that it transports is included, the method of improving the formation of the solid immobility cohesion lump in the blood vessel region is offered.動脈瘤の処置、高いフローフィステルでの動静脈奇形(AVM)の処置、および血管の塞栓形成に特に適している血管を塞栓形成するための新規組成物であって、(a)生体適合性ポリマー(b)生体適合性造影剤および(c)前記生体適合性ポリマーを可溶化する生体適合性溶媒を含み、ここで、血管部位に輸送した際に血管部位を塞栓するポリマー沈殿物を形成するのに十分量の前記ポリマーを用い、かつ、40℃で少なくとも約150cStの粘度を有することを特徴とする組成物を提供する。また、(a)哺乳動物の選択された血管部位に射出ポートを備えた輸送装置を配置し(b)40℃で少なくとも約150cStの粘度を有する、生体適合性ポリマー、生体適合性溶媒および任意に造影剤を含む組成物を、輸送装置の射出ポートを介して輸送することを含む、血管部位において固形の非移動性凝集塊の形成を向上させる方法を提供する。
