POLYMER INJECTABLE DETACHABLE COIL

摘要

Disclosed is a detachable coil for embolization capable of injecting a liquid polymer and useful for treating cerebral aneurysms, comprising: (I) a platinum coil part 1 for embolization in which a polymer coating film Ia is formed around an outer circumference of a platinum coil Ib having a cavity; (II) a coil pusher 2 in which an insulation coating film 2b is formed around an outer circumference of a hypo-tube 2a having a cavity; (III) a connection part 3, which includes a channel for injecting a specific polymer, that connects the platinum coil to the coil pusher and disconnects the platinum coil from the coil pusher by electrolysis; and (IV) a power supply device 4 for providing the power and performing the electrolysis of the connection part 3.
