Abstract:
1. A medical electrical lead comprising: a lead body that comprises a length between proximal end and a distal end, wherein the lead body defines a longitudinal axis extending between the proximal end and the distal end; a conductive element located within an interior of the lead body and extending along the longitudinal axis for at least a portion of the length of the lead body; a tubular electrode sub-assembly positioned over a portion of the lead body such that the longitudinal axis extends through the tubular electrode sub-assembly, wherein the tubular electrode sub-assembly comprises: one or more selected attachment sites at which the tubular electrode sub-assembly is positioned over and attached to underlying structure of the lead body, wherein the one or more selected attachment sites occupy only a portion of the inner surface of the tubular liner; and an electrical connection within the medical electrode lead between the coiled electrode and the conductive element.
