ABSTRACT:
A medical wire includes a conductive wire body and an implanted device connected to the distal end of the wire body through a joint member. The medical wire is inserted through a patient's tubular organ, thereby guiding the implanted device to the intended site in the patient's body. In this state, a monopolar high-frequency current is applied to the joint member through the wire body, thereby heating the joint member to cause it melt and sever, whereby the implanted device is detached from the wire body. There are thus provided a medical wire having an implanted device, which permits depositing the implanted device at the intended site in the patient's body by a simple operation within a short period of time, a mechanism which is simple in structure and highly reliable, and a method for depositing the implanted device of the medical wire is also provided.
