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.
