Abstract: 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.

Abstract: PURPOSE: An electroactive polymer vibrator, a manufacturing method thereof, and a thrombus dissolving method using the same are provided to minimize the amount of inputting a thrombus dissolving agent, thereby reducing thrombus dissolving risk due to drugs. CONSTITUTION: A plurality of electrode coating layers are formed on a portion of a columnar laminate. A capsule coating layer capsulates the electrode coating layers. An electroactive polymer is selected from either one of a conductive polymer and a dielectric polymer. The electroactive polymer is selected from polyaniline, polypyrrole, polysulfone, polyacetylene, and a combination thereof. The dielectric polymer is selected from polyacrylate, silicon, polyvinylidene, and a combination thereof.
