摘要:
PURPOSE: An angiostenosis polymer film and a method for manufacturing the same are provided to close blood vessels and to design the polymer film with coils of desired shapes and sizes. CONSTITUTION: A method for manufacturing an angiostenosis polymer film comprises the following steps: dissolving polymers in distilled water; adding cross-linking agents in different ratios after dividing the dissolved polymer solution into a first polymer solution and a second polymer solution; manufacturing a mixture of first and second polymer hydrogel films by adding a catalyst to the first and second polymer solutions; manufacturing first and second polymer hydrogel films by applying the mixture of first and second polymer hydrogel films on a plate and drying the mixture at room temperature; and adhering the first polymer hydrogel film to the second polymer hydrogel film by applying the mixture of first and second polymer hydrogel films between the dried first and second polymer hydrogel films. [Reference numerals] (AA) First polymer hydrogel film; (BB) Second polymer hydrogel film본 발명은 혈관폐색 고분자 섬유 및 이의 제조방법에 관한 것으로 가교제를 서로 다른 함량으로 포함하여 혈액 내에서의 팽창율이 서로 다른 제1 및 제2 고분자 수화겔 필름을 이중층 구조로 형성함으로써, 직선 형태의 고분자 섬유가 혈액 내에서 굽힘변형이 일어나 코일 형태로 형성되므로 혈관을 폐색할 수 있으며 가교제의 농도 및 고분자 섬유의 두께를 달리하여 원하는 형상 및 크기의 코일로 사전에 디자인할 수 있다.
