Method for producing a ring electrode with contacting opening
A recently granted patent (Publication Number: US11998734B2) discloses a method for producing a ring electrode, involving several steps such as providing an outer element comprising an outer tube, arranging inner elements made of sacrificial material inside the outer element, forming a composite tube, drawing the tube in a longitudinal direction, and creating an integral connection between the outer element and the inner elements using a diffusion agent. The method further includes removing the sacrificial material to obtain a contacting opening in the ring electrode. The patent also details variations in heating the composite tube for diffusion bonding, the use of different materials for the outer and inner elements, and the application of a diffusion agent selected from various metals and active solder.
Additionally, the patent covers the production of a ring electrode, an electrode system comprising the ring electrode and a conductor element, and the use of these components for producing implantable medical sensors or stimulators. The patent also includes claims for a composite tube used in producing the ring electrode, where the outer element, first inner element, and second inner element are arranged eccentrically to form the tube. The composite tube is designed for use in medical applications, highlighting the innovation in the manufacturing process of electrodes for medical devices. The patent provides a detailed and structured approach to creating ring electrodes, emphasizing the importance of materials, diffusion bonding, and the overall design of the electrode system for medical purposes.
