Abstract: A high frequency heating power device for an implanted device comprises a switch circuit, an input/output circuit, a high-frequency signal generating circuit, and a check circuit. When a high frequency output circuit applies a high frequency measuring voltage between a guide wire and the body ground board, a voltage is detected which corresponds to the impedance of a circuit which is made up of lead wires, the guide wire, the patient's body, and the body grounding board. It is determined by a discriminating circuit whether or not the voltage thus detected is in a predetermined allowable voltage range. The operator is informed of the discrimination by means of a display circuit and a buzzer circuit, so that he can determine the position of the end of the guide wire with respect to the end of the catheter with ease.

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.
