One aspect is a method of forming a lead for implantation. The method includes forming a distal end assembly, forming a proximal end assembly, and forming a flexible circuit coupling the distal end assembly to the proximal end assembly. The distal end assembly, the proximal end assembly and the flexible circuit are formed over an inner member. An outer member is placed over the combination of the distal end assembly, the proximal end assembly and the flexible circuit. The outer member and circuit are fused adjacent the distal end assembly to the proximal end assembly.

Lead body with flexible circuits and method

One aspect is forming a medical lead for implantation. The method includes forming a plurality of non-ground electrodes, at least one non-ground electrode having a plurality of segments. Overmold portions are formed for the at least one of the plurality of non-ground electrodes, including keys and tabs. One of a plurality of conductors is attached to one segment of the at least one non-ground electrode using the keys and tabs. The non-ground electrodes and plurality of conductors are assembled into electrode assembly and the overmold portions are reflowed. The reflowed electrode assembly is then ground to form the medical lead.

Overmolded segmented electrode

A lead body for implantation includes a first set of conducting sections, a second set of conducting sections, a strain relief coupler having a axial length with a plurality of tines extending along the axial length and extending radially thereby defining a plurality of axially-extending channels, a plurality of joints located within the plurality of channels, each joint coupling one conducting section from the first set of conducting sections to one conducting section from the second set of conducting sections, and an outer layer at least partially surrounding the first and second set of conducting sections, the plurality of joints and the strain relief coupler.

Strain relief coupler and method

A lead body for implantation includes at least one segmented electrode with a first electrode segment and a second electrode segment radially positioned about a lumen and electrically isolated from each other. A sectioned hypotube includes a distal end and a proximal end and a first conducting section and a second conducting section each extending between the distal and proximal ends. The first conducting section of the sectioned hypotube is coupled to the first electrode segment adjacent the distal end and the second conducting section of the sectioned hypotube is coupled to the second electrode segment adjacent the distal end.
