Systems and methods of forming contact assemblies for leads of electrical stimulation systems
First Claim
1. A method of forming an electrical stimulation lead, the method comprising:
- molding an electrically-nonconductive substrate over and between a plurality of spaced-apart electrically-conductive contacts to form a multi-contact lead assembly, the substrate having a first face and an opposing second face, the plurality of contacts each having a first face and an opposing second face, wherein the plurality of contacts are disposed along the first face of the substrate with the first face of each of the plurality of contacts exposed along the first face of the substrate and the opposing second face of each of the plurality of contacts covered by material forming the second face of the substrate, wherein the plurality of contacts comprises a first contact and a second contact;
coupling the multi-contact lead assembly along a first end portion of a lead body with the first face of the substrate conforming to a shape of an outer surface of the lead body and with the multi-contact lead assembly wrapping around the outer surface of the lead body;
electrically coupling individual conductors extending along a length of the lead body to each of the plurality of contacts of the multi-contact lead assembly; and
removing at least a portion of the substrate to expose the second faces of the contacts.

Abstract
A method of forming an electrical stimulation lead includes molding an electrically-nonconductive substrate over and between spaced-apart electrically-conductive contacts to form a multi-contact lead assembly. The contacts are disposed along a first face of the substrate with a first face of each of the contacts exposed along the first face of the substrate and an opposing second face of each of the contacts covered by material forming a second face of the substrate. The multi-contact lead assembly is coupled along a first end portion of a lead body with the first face of the multi-contact lead assembly conforming to a shape of an outer surface of the lead body, and with the multi-contact lead assembly wrapping around the outer surface of the lead body. Conductors extending along a length of the lead body are electrically coupled to each of the contacts of the multi-contact lead assembly.
