摘要

本文报道了一种用于医用的具有弯曲、扭转和延伸功能的主动导管的批量制造新方法。主动导管由形状记忆合金(SMA)线圈和不锈钢内衬线圈组成。SMA线圈和内衬线圈采用电镀镍和丙烯酸树脂电沉积连接。这种新方法使低成本组装和小直径(/spl phi/1.4 mm)成为可能。提出了一种适用于有源导管的小直径薄壁管状结构制造新方法。管状结构由不锈钢弹簧线圈、蒸发聚对二甲苯膜和浸涂生物相容性聚氨酯组成。

Bending, torsional and extending active catheter assembled using electroplating

This paper reports a new batch fabrication method of active catheters which have bending, torsional and extending functions for medical applications. The active catheter consists of shape memory alloy (SMA) coil for actuator and a stainless steel liner coil. The SMA coil and the liner coil are connected using nickel electroplating and acrylic resin electrodeposition. This novel method makes low cost assembly and small diameter (/spl phi/1.4 mm) possible. The new fabrication method of small diameter and thin wall tubular structure which is suitable for active catheters was developed. The tubular structure consists of stainless steel spring coil, evaporated parylene membrane and dip coated biocompatible polyurethane.
