Abstract
A catheter for delivering electrical energy to a selectable region of a patient's body has at least one layer of fibers with at least one electrically conductive fiber stranded over a flexible core. Each layer of fibers is stranded over the flexible core and underlying layers opposite in direction from that of the immediately preceding layer so as to provide a catheter with good torque transfer properties in addition to its electrical energy transfer properties. The outermost layer of stranded fibers is electrically conductive and is covered by an electrically insulative outer layer which is mechanically strippable to expose selectable regions of the underlying layer of stranded fibers. Electrical energy is transmitted along the outermost layer of stranded fibers to tissue which is in contact with the exposed contact region of the outermost layer of stranded fibers.
