Abstract

A device for invasive use, comprising a support member comprising a flexible material. The support member comprises a layer of a conductive line or pattern thereon. The support member is formed into an elongated tube shape, and the inside of the support member can be sealed from the outside of the support member. An electrically conductive line or pattern extends on the inside of the tube shaped support member, and the support member may comprise a sensing, stimulating and/or processing element. Furthermore, there is described a manufacturing method for the device, a system where the device is a part of the system and the use of the device for invasive use.
