Problems solved by technology

[0004] Part of the electrodes of the implantable electrical nerve stimulation system, the connection head of the electrode-extension wire, the extension wire and the pulse generator are all implanted under the skin of specific parts of the human body. Immunological rejection such as rejection and aseptic infection will occur, resulting in complications and implant failure after the implantable electrical nerve stimulation system is implanted into the human body

Embodiment Construction

[0023] figure 1 is a schematic diagram of the implantable electrical nerve stimulation system. refer to figure 1 , The implantable nerve electrical stimulation system usually mainly includes a pulse generator 1 implanted in the body, an extension lead 2 and an electrode 3, and a control device located outside the body. The control device controls the pulse generator, the pulse generator 1 is connected to the extension wire 2, and the extension wire 2 is further connected to the electrode 3; thus the pulse generated by the pulse generator 1 is transmitted to the electrode 3 to electrically stimulate the nerve .

[0024] Wherein, a part of the electrode 3 is implanted in a specific part 4 of the human body such as the brain, spinal cord, peripheral nerves or autonomic nerves. The other part of the electrode 3, the connecting part of the electrode 3 and the extension lead 2, the extension lead 2 and the pulse generator 1 are all implanted under the skin of a specific part of t...

Abstract

The invention provides an implanted nerve electrical stimulation system with a drug release device, comprising an electrode and a drug release device, wherein the drug release device is provided with a through hole used for being passed by the electrode so that the drug release device is sleeved on the electrode; one or more chambers are arranged in the drug release device and used for accommodating drugs; the drug release device is provided with one or more holes, the holes are communicated with the chamber and the outside of the drug release device. According to the implanted nerve electrical stimulation system with the drug release device, the drugs for preventing or treating symptoms, such as subcutaneous immune rejection reaction and the like can be released through the drug release device, therefore, the symptoms, such as subcutaneous immune rejection reaction and the like generated by implanting the implanted nerve electrical stimulation system into a human body can be prevented or treated.

Description

technical field [0001] The invention relates to an implanted electrical nerve stimulation system, in particular to a drug releasing device of the implanted electrical nerve stimulation system. Background technique [0002] Electrical nerve stimulation plays an important role in the treatment of nerve dysfunction and rehabilitation of nerve injury. The implantable nerve electrical stimulation system releases electrical stimulation of a specific frequency by implanting electrodes in specific parts of the human body such as the brain, spinal cord, peripheral nerves, or autonomic nerves, so as to treat diseases with abnormal nervous system functions or improve the nervous system. purpose of disease symptoms. [0003] Known implantable electrical nerve stimulation systems generally mainly include a pulse generator, electrodes and extension wires implanted in the body, and a control device located outside the body. The control device controls the pulse generator, and the pulse g...
