Electrical lead, processing method, extension cord, electrode and electrical stimulation system

Abstract

The invention provides an electrical lead, a processing method, an electrode extension cord, an implantable biological electrode and an implantable electrical stimulation system. The electrical lead comprises a conductive body arranged in a spiral mode; the conductive body comprises an outer skin and a plurality of conductive structures insulated from one another; the outer skin wraps the conductive structures insulated from one another; each conductive structure comprises a plurality of conductive wires; all the conductive structures are arranged side by side; and the cross section of the conductive body is flat. The processing method comprises the following steps that a plurality of conductive wires are processed into the conductive structures; and a plurality of conductive structures which are insulated from one another are processed into the conductive body which is spirally arranged and has the flat cross section. According to the conductive structure, the situation that the whole conductive path is disconnected due to breakage of a certain conductive wire in the conductive structure in the using process can be avoided, and meanwhile the risk that the whole product fails due to breakage of the certain conductive wire in the conductive structure caused by inevitable damage in the production process can be reduced.

Description

Technical field [0001] The present invention relates to the field of medical devices, and Background technique [0002] Implanted active medical devices have been widely used to treat multiple conditions, especially in the treatment of physiology, psychological diseases, which has more excellent and direct efficacy relative to many traditional treatment methods. One of the implantable active devices is a neuroelectric stimulator that passes the pulse signal to the neuronal tissue to improve the normal skill operation of the human body, such as the implantine deep neurostat (DBS) Effective improvement of physical control and coordination of Parkinson patients. [0003] Parkinson's Disease (PD) is a common neurological denatured disease, drug treatment is the primary and medium main treatment methods. With the gradual increase in drug dosage and the development of the condition, the risk of side effects of drugs, the patient's psychological burden and the drug resistance of patient...

Problems solved by technology

[0007] The electric wires in the prior art are generally monofilament spiral type. Although the monofilament spiral electric wire can meet the requirements of fatigue resistance and elasticity, considering the raw materials and production may cause certain damage to the guide wire and the damage is difficult to detect and remedy. As a result, the probability of simultaneous conduction of multiple channels of a single-filament helical electrical conductor, such as 8 channels, is very low, which greatly increases the post-production cost
