ACTIVE BIO-IMPLANTED PULSATILE HIGH-FREQUENCY STIMULATOR FOR CATHETER FOR STIMULATING TRANSSACRAL EPIDURAL SPINAL NERVE

摘要

The present invention relates to an active in vitro pulsatile high-frequency stimulator enabling electric stimulation through an electrode by means of generating and providing, in vitro, a signal for controlling the generation of pulsatile high-frequency signal information determined according to the symptoms of a patient and a driving power for electric stimulation, receiving the pulsatile high-frequency signal information and the driving power through an antenna implanted on the coccygeal vertebral site of the human body, and generating a pulsatile high-frequency signal in vivo, the present invention comprising: a device for controlling the generation of pulsatile high-frequency signal information, the device responding to a pulsatile high-frequency generation request signal which is input according to the state of a patient, generating a pulsatile high-frequency signal and a driving power respectively, converting same into wireless signals, then transmitting same; and an active bio-implant-type catheter provided by being implanted inside the body of the patient, receiving the driving power and using same as a driving power source for generating a pulsatile high-frequency signal, receiving a high-frequency signal and converting same into a pulsatile high-frequency signal, and enabling an electric stimulus to be applied to a corresponding site. An electrode of the active bio-implant-type catheter is configured so as to be one or a plurality of electrodes; the location of a stimulating electrode may be selected on the basis of in vivo electrode location information set on an external device; and a synchronization mode may be serviced for stimulus-synchronizing two active bio-implant-type catheters for inserting the two active bio-implant-type catheters in vivo and stimulating a desired spinal nerve interval. As such, the present invention has the effect of not only enabling the alleviation of pain or a neurological abnormality of a patient, but also improving pain treatment or neuromodulation treatment for a neurological abnormality.
