One aspect relates to a process for preparing a ring electrode including the steps of a) providing a monolithic metal precursor, wherein the monolithic metal precursor includes an outer tube forming a first cavity of the precursor, and wherein the outer tube has a wall including in one section an inner tube forming a second cavity of the precursor; b) preparing a composite precursor by inserting a first sacrificial core element into the first cavity of the precursor provided in a) and a second sacrificial core element into the second cavity of the precursor provided in a); c) forming the composite precursor obtained in b) to obtain a formed composite having a smaller outer diameter than the composite precursor obtained in b); d) separating a composite disk from the formed composite obtained in c); e) removing the first and the second sacrificial core element from the composite disk obtained in d).

Ring electrode for a medical device

One aspect relates to a process for preparing a shaped metal product, wherein a monolithic metal precursor surrounded by a sacrificial outer element is formed to smaller dimensions, and the sacrificial material is subsequently removed. One aspect further provides a composite for preparing a shaped metal product, and a shaped metal product. Such shaped metal products can be used to manufacture an active implantable medical device or sensor.
