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