Electrode having erectable lead
First Claim
1. An implantable electrode comprising:
- an electrode body having a front end, a back end, a top surface, and a bottom surface; and
a lead having an electrode engaging portion extending into and affixed to said electrode body, said electrode engaging portion of said lead extending into said electrode body from an utmost distal edge of said back end of said electrode body and terminating at a lead terminal point located between the front end and the back end of said electrode body, wherein said electrode engaging portion is configured to sit entirely within the electrode body when in a first position;
wherein a section of said electrode engaging portion of said lead is erectable from said first position to a second position in which said section of said electrode extends away from said electrode body.

Abstract
Disclosed is an electrode, such as an SCS paddle electrode, having a lead attached thereto along an interior portion of the electrode. The lead and electrode are configured such that the lead may be positioned generally coplanar with a top surface of the electrode, and may likewise be erected from such coplanar orientation up and away from the top surface of the electrode. Thus, the lead can maintain the typical configuration of emerging from the back end of the electrode, but because at least portions of the lead are not permanently bonded into the electrode paddle, the lead (when desired) can be pulled upward, with or without surrounding strain relief material, to emerge from the top surface of the paddle at an angle or curve to such top surface. This allows the base of the paddle to engage a bony opening, such as when the electrode is inserted into a patient'"'"'s spine, skull, plane of fascia, etc.

7. A method for implanting an electrode, comprising:
-
creating an aperture at a target location in a patient'"'"'s body; inserting an implantable electrode having an erectable lead into said aperture, wherein said erectable lead comprises an electrode body having a front end, a back end, a top surface, and a bottom surface, said erectable lead further comprising an electrode engaging portion extending into and affixed to said electrode body, said electrode engaging portion of said erectable lead extending into said electrode body from an utmost distal edge of said back end of said electrode body and terminating at a lead terminal point located between the front end of said body and the back end of said body, wherein said electrode engaging portion is configured to sit entirely within the electrode body when in a first position, and wherein a section of said electrode engaging portion of said erectable lead is erectable from said first position to a second position in which said section of said electrode extends away from said electrode body; raising the erectable lead upward and away from said top side of said implantable electrode; and moving said electrode body so that said electrode body is positioned below said aperture and said erectable lead extends through said aperture.
