Problems solved by technology

At present, a wire-free electrode has appeared on the market. The wire-free electrode can be placed in the epidural area of ​​the spinal cord to stimulate the sacral nerve root or the posterior pelvis to stimulate the spinal cord and sacral nerve. After the wire-free electrode is implanted in the target tissue of the patient's spine, if Without a fixed structure, when the patient moves, it may cause the movement of the leadless electrode, which will be displaced to the non-target tissue area, resulting in no actual effect of the electrical stimulation treatment or stimulation side effects due to stimulating the wrong tissue area

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0018] Implantable neurostimulators generally include an implantable pulse generator and electrodes. The implantable pulse generator is used to generate electrical pulses according to the parameters programmed by the doctor. The electrodes are used to transmit electrical pulses to the target nerves. Wire-free electrodes It can be placed in the epidural area of ​​the spinal cord to stimulate the sacral nerve root or in the posterior pelvis to stimulate the spinal sacral nerve.

[0019] In a specific embodiment of the presen...

Abstract

The present invention belongs to the implantable nerve stimulator field and relates to an implantable conductor-less electrode. The implantable conductor-less electrode comprises an electrode substrate; the electrode substrate is provided with one or more protrusions; the protrusions have accommodating cavities; the accommodating cavities are filled with an adhesive; and the adhesive is released from the protrusions to fix the electrode in a target tissue after the electrode is implanted into the target tissue. According to the implantable conductor-less electrode of the invention, the protrusions are additionally arranged on the conductor-less electrode so as to be adopted as fixing structures; the protrusions accommodate the adhesive, after the electrode is implanted into the target tissue, the adhesive in the fixing structures is released, and is solidified after meeting the moisture of the body of a person, so that the electrode can be firmly fixed and is embedded in the target tissue, and therefore, the electrode can be prevented from moving when the electrode is used, and the effect of electrical stimulation can be ensured.

Description

technical field [0001] The invention relates to the field of implantable nerve stimulators, in particular to an implantable leadless electrode. Background technique [0002] Implantable neurostimulator is an emerging digital therapeutic instrument. Implantable neurostimulator generally includes an implanted pulse generator and electrodes. The implanted pulse generator is used to generate electrical pulses according to the parameters set by the doctor's program. The electrodes Used to deliver electrical impulses to targeted nerves. At present, a wire-free electrode has appeared on the market. The wire-free electrode can be placed in the epidural area of ​​the spinal cord to stimulate the sacral nerve root or the posterior pelvis to stimulate the spinal cord and sacral nerve. After the wire-free electrode is implanted in the target tissue of the patient's spine, if Without a fixed structure, when the patient moves, it may cause the movement of the leadless electrode, which wi...
