CATHETER GUIDE WIRE AND CATHETER |
摘要 |
A catheter guide wire which, despite its reduced diameter, exhibits improved strength and resistance to corrosion by body fluids and medicine. The catheter guide wire 10 is composed of a stainless steel core wire 11, a winding of a low carbon duplex structure steel wire 13 having a diameter smaller than 30 .mu.m and a tensile strength higher than 300 kgf/mm2, said winding covering the core wire such that the low carbon duplex structure steel wire runs obliquely to the axis of the core wire 11 and crosses each other, and a polyester resin film 15, thinner than 3 .mu.m, covering the low carbon duplex structure steel wire 13. The catheter is composed of a resin inner tube and a low carbon duplex structure steel wire 13 covered with a polyester resin film 15, which runs around the resin inner tube obliquely to the axis and crosses each other.
