Methods The present study is a randomized comparative clinical trial. 607 healthy parous women were randomly allocated into GyneFix IN group (n=302) or TCu 380A group (n=305). IUD was inserted during the menstrual interval by the trained investigators. Follow-up were arranged at 1,3,6 and 12 months after insertion. The discontinuation rates were calculated by life table method.

Methods 1020 patients (672 male, 348 female, mean age 57.8±2.4 yr) undergoing CAG or PCI were randomized into either the Angioseal group (CAG 380, PCI 120) or the Perclose group (CAG 392, PCI 128). The procedural success rate and occurance of local complications were compared between the two groups. Results Both kinds of devices had a high success rate (Angioseal 94% vs Perclose 96%) and there was no statistical difference between them.

l020例行冠脉造影及介入治疗的患者（男672例，女348例，年龄57.8±2.4岁）经髂动脉造影证实无血管闭合器使用禁忌，术后随机分为Angioseal组（CAG 380例，PCI 120例）和Perclose组（CAG 392例，PCI 128例），比较两组患者使用血管闭合器的成功率及局部并发症的发生率。
