Abstract

An implantable system that includes a lead and an implantable signal generator wherein the plurality of electrical contacts and the plurality of insulating regions on the lead, and the plurality of electrical connectors and the plurality of electrical insulators in the connector block are configured so that each of the plurality of electrical contacts form operable connections to the electronic circuitry through each of the plurality of electrical connector, and the insulating regions and the electrical insulators electrically isolate adjacent operable connections. Leads, and methods are also disclosed.

Claims

1-15. -15. (canceled)

16. An implantable electrical lead comprising:

a) a lead body having a proximal end, a proximal portion and a distal portion;

b) a plurality of electrodes located at the distal portion of the lead body;

c) a plurality of electrical contacts located at the proximal portion of the lead body, wherein each of the plurality of electrical contacts has a contact length along the lead body;

d) a plurality of insulating regions located at the proximal portion of the lead body, wherein each of the plurality of insulating regions has an insulating length along the lead body; and

e) a plurality of conductive means that electrically couple the plurality of electrodes to the plurality of electrical contacts,

wherein the contact length of an electrical contact of the plurality of electrical contacts that is positioned proximal to another electrical contact of the plurality of electrical contacts is different from the other contact lengths.

18. The implantable electrical lead according to claim 16, wherein one of the plurality of insulating lengths is different from the other insulating lengths.

20. The implantable electrical lead according to claim 16, wherein more than one of the plurality of insulating lengths is different from the other insulating lengths.

21. The implantable electrical lead according to claim 16, wherein more than one of the plurality of contact lengths is different from the other contact lengths.
