Abstract
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.
Claims20
A method of forming a medical lead for implantation comprising:
- forming a plurality of non-ground electrodes, at least one non-ground electrode having a plurality of electrode segments;
- forming overmold portions for the at least one of the plurality of non-ground electrodes, the overmold portions comprising keys and tabs;
- attaching one of a plurality of conductors to one electrode segment of the at least one non-ground electrode using the keys and tabs;
- assembling the non-ground electrodes and plurality of conductors into an electrode assembly;
- reflowing the overmold portions;
- and
- grinding the reflowed electrode assembly to form the medical lead.
An electrode assembly for making an electrode lead, the electrode assembly comprising:
- a plurality of non-ground electrodes, at least one non-ground electrode having a plurality of electrode segments;
- overmold portions on the at least one of the plurality of non-ground electrodes, the overmold portions comprising keys and tabs;
- a plurality of conductors, wherein one conductor from the plurality of conductors is coupled to one electrode segment of the at least one non-ground electrode at a location that is based at least in part on the relative radial location of the keys and tabs.
A non-ground electrode for making an electrode lead, the non-ground electrode comprising:
- a plurality of electrode segments defined between a plurality of slots;
- overmold portions on the non-ground electrode, the overmold portions comprising keys and tabs;
- a plurality of conductors, wherein one conductor from the plurality of conductors is coupled to one electrode segment of the non-ground electrode at a location that is based at least in part on the relative radial location of the keys and tabs.
