Cluster stimulating micro electrode array capable of being implanted into nerve system of human body

Abstract

The stimulating cluster micro electrode array capable of being implanted into nerve system of human body belongs to the field of medical prothesis. The present invention includes stimulating metal wire micro electrode, supporting metal wire micro electrode, stimulating metal wire micro electrode cluster, stimulating metal wire micro electrode cluster array, and micro electrode substrate. Several stimulating metal wire micro electrodes are adhered onto the outer wall of one supporting metal wire micro electrode to constitute one stimulating metal wire micro electrode cluster; several stimulating metal wire micro electrode clusters are fixed onto one micro electrode substrate to constitute one stimulating metal wire micro electrode cluster array; and lead wires are led out from the micro electrode substrate for connection with outer equipment. The electrodes are made with biocompatible metal material. The present invention is used in stimulating nerve system in limited space.

Description

technical field [0001] The invention relates to an implantable microelectrode in the technical field of medical prosthesis, in particular to a cluster stimulation microelectrode array which can be implanted into the human nervous system. Background technique [0002] The field of neuroprosthetics includes motor neuroprostheses, cochlear implants (cochlear implants) and optic neuroprostheses, among others. Motor neuroprostheses are microelectronic devices of the nervous system developed through deep brain stimulation to treat movement disorders such as Parkinson's disease (PD). Deep brain stimulation often uses an embedded electrical stimulation system, which generally consists of three parts: implanted electrodes, connecting wires to the subcutaneous receiver, and an electrical stimulator. After the electrodes are implanted, select certain stimulation parameters and different electrode stimulation contacts to observe the effect of implantation and record the parameters of d...

AI Technical Summary

Problems solved by technology

Although this invention also considers the problem of realizing the high density of the electrode array, it only provides a four-electrode array

Since the electrodes have the same length, it does not take into account the stimulation of nerve fibers at different depths when used on nerve bundles, and does not fundamentally solve the efficiency and practical problems of electrical stimulation of the human nervous system. Therefore, the comprehensive performance of this type of electrode Still needs further improvement
