A multiple-conductor electrical lead for use with medical device systems and a method of manufacture is disclosed. The multiple-conductor electrical lead comprises a central core and has at least one conductor, typically in the form of a ribbon cable, coiled around it along its length. Typically one or more ribbon cables coiled around a central core each comprise a plurality of separate electrical conductors both coupled together along their lengths in series and electrically insulated from one another with an insulating material. The material of the central core, e.g. polyester, stainless steel, nickel titanium, and the structural configuration, e.g. wrapping pitch of the ribbon cable around the central core and number of ribbon cables, are selected based on desired mechanical characteristics. Such multiple-conductor electrical leads are useful, for example, with analyte sensor systems such as amperometric glucose sensor systems used in the management of diabetes. |
