ABSTRACT:
A method of making an active slender tube as implemented as a catheter, guide wire, or any other medical or non-medical micro-mechanical or -system or system's active micro-component is disclosed, comprising preparing an actuator made from a shape memory alloy (SMA) and forming at least a portion of a tubular body; disposing outside of SMA made actuator an elastically deformable outer skeleton coaxially therewith; and fastening together SMA made actuator and outer skeleton wire adjacent to non-insulated portions, step of fastening includes a step of passing an electric current through a lead wire while in an electroplating liquid to deposit a metal on lead wire and non-insulated portions from said liquid and thereby to electrically join SMA made actuator and outer skeleton together at corresponding areas.
