Abstract

One aspect relates to a method of producing a sleeve for a ring electrode for electrophysiological and neuro-medical applications from a biocompatible metallic tape. Repetitive structures are punched into the tape and each includes at least one surface that is connected by at least one fin to at least one external strip. The at least one external strip connects the repetitive structures to each other on the margin. A sleeve mold is formed from a multiple of the repetitive structures through multiple reforming steps by a reforming technique. The sleeve mold is punched off the such that the sleeve is formed with a first tube-shaped region with a larger diameter and a second tube-shaped region with a smaller diameter. The first region with the larger diameter has a larger external diameter and internal diameter than the second region with the smaller diameter, and the two regions are connected.
