Abstract: A device for implanting catheters has a tube with a wall and a wire. The tube is intended to be introduced into a body so that at least one catheter can be inserted for implantation through the tube. The wall of the tube has an inside surface and an outside surface. The wire is preferably fixed at its first end in the region of the proximal end of the tube to the inside surface or the outside surface of the wall and the wire is guided in the proximity of that surface along the longitudinal direction of the tube from the proximal end of the tube to the distal end thereof and is then returned in the proximity of the respective other surface of the wall along the longitudinal direction from the distal end of the tube to the proximal end thereof. The wire is used to cut the tube open after insertion of the catheter.

Abstract: The invention is based on the notion of providing a device for implanting catheters, which has a tube with a wall and a wire. In that case the tube is intended to be introduced into a body so that at least one catheter can be inserted for implantation through the tube. The wall of the tube has an inside surface and an outside surface. The wire is preferably fixed at its first end in the region of the proximal end of the tube to the inside surface or the outside surface of the wall and the wire is guided in the proximity of that surface along the longitudinal direction of the tube from the proximal end of the tube to the distal end thereof and is then returned in the proximity of the respective other surface of the wall along the longitudinal direction from the distal end of the tube to the proximal end thereof.

Abstract: A neural electrode arrangement comprises an elastically deformable carrier body defining a cylindrical internal space therein, and at least one electrode which is fixedly connected to the carrier body and which is in peripherally touchingly operative relationship with the internal space in the carrier body. The electrode is formed from an elongated wire coil.
