a bone or curves around tissue fig4 a shows additional embodiment of the invention that is a multi stranded fce lead in which a parallel leads 12 conduct signals along separate fces 14 the multiple leads 12 can be wrapped within a multi lead sheath 40 which contains both the leads 12 and inter lumen space 42 which in practice will be minimized but which can also be filled with either a gas or liquid these multiple strands can terminate at electrically isolated portions of the lead connectors in order to carry unique signals across the lead or can serve as a redundant system for carrying a single electrical signal alternatively pairs of strands which are likely to be simultaneously kinked e g pairs located opposite each other can carry a particular signal in a redundant fashion fig4 b shows an additional embodiment of the invention in which the lead body 12 contains a fce 14 and in which an intra lead support matrix 44 is also provided the intra lead support matrix 44 may be comprising one or more supporting endoskeletal members which in this case are a horizontal support 44 a vertical support 44 b the supports 44 may be locally positioned and discontinuous or may extend along approximately the entire length of the lead body 12 in the latter case the division of the fce 14 permits either of two.
