Abstract
A paddle lead includes a plurality of electrodes configured in at least three rows of three electrodes with the second, intermediate row operable to provide anode guarding. The paddle lead further includes a plurality of grooves disposed on a surface opposite the electrodes to facilitate the insertion of the paddle lead within a patient by inhibiting the veering of the paddle lead to one side or the other of the dorsal column as the paddle lead is advanced along the dorsal column midline during implantation.
Claims10
A paddle lead, comprising:
- a body having a first side and a second side, a first end and a second end, and a first edge and a second edge;
- a plurality of parallel grooves on the second side of the body and extending from the first end towards the second end, such that when the paddle lead is being implanted in a patient, at least a portion of the plurality of grooves engage the patient and facilitate advancement of the paddle lead towards a target implant site by inhibiting the paddle lead from veering away from a target implant site;
- the first side of the body including at least a first row of at least three electrodes, a second row of at least three electrodes and a third row of at least three electrodes;
- each of the first, second and third row of electrodes being generally parallel and extending from the first edge of the body to the second edge of the body, with the second row being positioned intermediate the first and third rows;
- and
- the second row of electrodes operable to provide anode guarding for at least one of the first and third rows of electrodes with each of the electrodes in the second row being electrically connected together and operating in a common state.

A paddle lead, comprising:
- an elongated body having a length and a width, a first side and a second side, and a first edge and a second edge;
- a plurality of grooves on the second side of the body and extending along the length of the body, with a first of the plurality of grooves extending the entire length of the body, such that when the paddle lead is being implanted in a patient, at least a portion of the plurality of grooves engage the patient and facilitate advancement of the paddle lead towards a target implant site by inhibiting the paddle lead from veering away from a target implant site;
- the first side of the body including at least a first row of at least three electrodes, a second row of at least three electrodes and a third row of at least three electrodes;
- each of the first, second and third row of electrodes being generally parallel and extending from the first edge of the body to the second edge of the body, with the second row being positioned intermediate the first and third rows;
- and
- the second row of electrodes operable to provide anode guarding for at least one of the first and third rows of electrodes with each of the electrodes in the second row being electrically connected together and operating in a common state.
