Abstract
An implantable electrical line including a lead, wherein the lead includes at least one helically wound electrical conductor. The at least one helically wound electrical conductor is surrounded by a fiber braid, which is formed by at least two fibers or fiber bundles, and wherein the at least two fibers or fiber bundles are interwoven and wound around the electrical conductor in opposite winding directions.
Claims12
An implantable electrical line comprising:
- a lead or a lead segment, wherein said lead or said lead segment comprises at least one helically wound electrical conductor,
- wherein the at least one helically wound electrical conductor is surrounded by a fiber braid comprising at least two fibers or fiber bundles,
- wherein the at least two fibers or fiber bundles are interwoven and are wound around the at least one helically wound electrical conductor in opposite winding directions,
- wherein the at least one helically wound electrical conductor and the fiber braid form one or more a inductors and capacitors, and
- wherein the one or more of inductors and capacitors forms a filter that blocks at frequencies of electromagnetic fields prevailing in magnetic resonance imaging (MRI) scanners.
