Implantable sacral nerve stimulator provided with electric-field intensity measurement device

Abstract

The invention relates to the field of implantable sacral nerve stimulators and particularly discloses an implantable sacral nerve stimulator provided with an electric-field intensity measurement device. The implantable sacral nerve stimulator comprises an external program controller, an implantable pulse generator and a stimulating electrode and further comprises an electric-field intensity sensor, wherein the electric-field intensity sensor is arranged at the target nerve and monitors the intensity of an electric field produced by the stimulating electrode, the electric-field intensity sensor transmits monitored data to the implantable pulse generator or the external program controller. The implantable sacral nerve stimulator can monitor the relative position of the stimulating electrode and provides convenience for the stimulating electrode when the implantable sacral nerve stimulator is installed. In addition, in the using process of the implantable sacral nerve stimulator, a patient and a doctor can immediately aware of it when the stimulating electrode displaces, and the treating quality is ensured.

Description

technical field [0001] The invention relates to an implanted nerve stimulator, in particular to an implanted nerve stimulator with an electric field intensity measuring device. Background technique [0002] Implantable neurostimulators deliver electrical stimulation signals to target nerves through stimulating electrodes, but as the patient moves, the stimulating electrodes may be displaced within body tissues, thereby affecting the therapeutic effect of electrical stimulation. Although the prior art provides various fixing devices to prevent the positional displacement of the stimulating electrodes in the body tissue, such as US7865250B2 (Medtronic), US8145323 B2 (Medtronic), US8260436 B2 (Medtronic), US8019443B2 (Boston Medicine), and Electrode displacement cannot be absolutely avoided. Moreover, when the stimulation electrodes are displaced, the patient and the doctor cannot realize it immediately, which will lead to a decline in the therapeutic effect. [0003] In addi...
