INDWELLING-COIL FOR FORMING AN EMBOLUS CAPABLE OF TREATING A BLOOD VESSEL OF A CEREBRAL ANEURYSM AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: An indwelling-coil for forming an embolus and a manufacturing method thereof are provided to form a bending unit and two angle changing units which are connected each other on a unit spiral coil of a secondary coil, thereby precisely embedding the coil in a cerebral aneurysm.;CONSTITUTION: A spiral coil includes a primary coil(1) and a secondary coil(2). A plurality of bending units(12) is formed on a unit spiral coil(11). The bending units are integrated with angle varying units(13,14). The angle varying units are bent along with the inner side of an indwelling-coil. The bending unit and the angle varying units face each other on each unit spiral coil.;COPYRIGHT KIPO 2011
