摘　　要：本文研究了用 于介入栓塞颅内 动脉瘤的不锈 钢弹簧圈在 生理盐 水中阳 极溶解 电化 学过程， 确定 了溶断弹簧圈的 电流范围。分析 了不同材料及 表面预处理 对不锈 钢孔蚀 电位的 影响， 为电解 脱离 弹簧圈的选择提The anodic dissolution processes of stainless steel coil used in endovascular treatment of lntracranial Aneurysms were investigated. The range of current for electrolysis detachment was determined. The effect of different materials and surface pretreatment on pitting potential of stainless steel was also analysed. All of the results would be used for the choice of electrolysis detachtable coil used in embolization of Intracranial Aneurysms via endovascular approach.
