Abstract
An implantable lead includes an expandable paddle body and a plurality of electrodes disposed on the paddle body. The electrodes are configured and arranged to provide electrical stimulation to adjacent tissue when implanted and the lead is coupled to a control module. The paddle body is configured for percutaneous implantation through an introducer followed by expansion of a volume of the paddle body by at least 10%. Alternatively, the paddle body is configured for percutaneous implantation and when implanted the lead is configured and arranged so that a position or orientation of the plurality of electrodes relative to the paddle body can be altered.

8. A kit for implanting a lead, comprising:
-
a lead comprising a paddle body with a plurality of electrodes disposed on the paddle body, wherein at least one of the electrodes has an identification feature to allow determination of an orientation of implantation of the lead by observation of the identification feature; and a needle introducer with a non-circular, closed-path, transverse cross section through which the paddle body of the lead can be percutaneously implanted into tissue of a body and then withdrawn from the lead, wherein the needle introducer comprises a plurality of windows configured and arranged permit stimulation of tissue adjacent to at least one of the plurality of windows by alignment of at least one of the electrodes of the lead with the at least one of the plurality of windows while still disposed within the needle introducer. - View Dependent Claims (9)

12. A method for percutaneous implantation of a lead of an electrical stimulation system, the method comprising:
-
inserting an introducer through skin of a patient with at least a portion of the lead disposed in the introducer, the lead comprising a paddle body with a plurality of electrodes disposed on the paddle body; positioning the lead near tissue to be stimulated including observing an identification feature on at least one of the electrodes to determine an orientation of implantation of the lead, wherein the identification feature comprises at least one indentation asymmetrically positioned on the shape of the at least one of the electrodes; withdrawing the introducer leaving the lead implanted in the patient; and expanding a volume of the paddle body by at least 10% after implanting the lead. - View Dependent Claims (13, 14, 15, 16)
