Abstract
One aspect relates to a method for producing a layered structure, including providing a substrate, forming a first layer onto at least part of the substrate, the first layer being a first polymer, and forming a second layer onto at least part of the first layer, the second layer being a second polymer. The substrate and the second layer are electrically conductive and the first layer is insulating or the substrate and the second layer are insulating and the first layer is electrically conductive. Forming each of the first and second layers includes forming such that each layer is no more than one tenth of the thickness of the substrate.
Claims13
A method for producing a layered structure comprising:
- providing a substrate having a thickness and comprising a material that is biocompatible;
- forming a first layer onto at least part of the substrate, the first layer being a first biocompatible polymer;
- forming a second layer onto at least part of the first layer, the second layer being a second biocompatible polymer;
- wherein the substrate and the second layer are electrically conductive and the first layer is insulating or the substrate and the second layer are insulating and the first layer is electrically conductive;
- and
- characterized in that forming each of the first and second layers comprises forming such that each of the first and second layers is no more than one tenth of the thickness of the substrate and such that each are configured for implantation within the human body.
A method for producing a layered cylindrical structure comprising:
- providing a substrate having a diameter and comprising a material that is biocompatible;
- forming a first layer onto at least part of the substrate, the first layer being a first biocompatible polymer;
- forming a second layer onto at least part of the first layer, the second layer being a second biocompatible polymer, such that both the first and second layers are configured for implantation within the human body;
- wherein the substrate and the second layer are electrically conductive and the first layer is insulating or the substrate and the second layer are insulating and the first layer is electrically conductive;
- and
- characterized in that forming each of the first and second layers comprises forming such that each of the first and second layers has a thickness that is no more than one tenth of the diameter of the substrate such that overall dimensions of the layered structure are substantially determined by the diameter of the substrate.
