The biological implantation device for urination control is started. Vivo implantation apparatus according to the embodiment of the present invention is bio-signal measurement unit is connected to a part of the body for measuring a physiological signal corresponding to the state of the bladder; Receiving the stimulation information for a given stimulus from the outside via wireless communication or the wireless transmitting and receiving unit for transmitting a transmission signal corresponding to the bio-signal to the outside; Wireless transmitting and receiving unit for transmitting a transmission signal corresponding to the bio-signal to the outside; And then based on the stimulation information received through the said radio transceiver generates a stimulus signal for giving a predetermined stimulus to the bladder and is applied to the magnetic pole portion of the stimulation signal, the generated, the transmission signal corresponding to the bio-signal a microcomputer for providing the radio transceiver; And it may include a magnetic pole which could cause the bladder according to the stimulus signal.
