IMPLANTABLE MEDICAL LEAD
First Claim
1. An implantable medical lead comprising:
- an elongate central body having an axis;
a first extendable member pivotably moveable relative to the central body such that a portion of the extendable member is configured to move from a retracted position relative to the axis of the elongate central body to an extended position where the portion of the extendable member extends laterally beyond the central body;
a first electrode disposed on the central body; and
second and third electrodes disposed on the extendable member,wherein the first, second and third electrodes each have a center, andwherein the centers of the first, second and third electrodes are co-linearly arranged when the extendable member is in the extended position.

Abstract
An implantable medical lead includes an elongate central body having an axis and a first extendable member pivotably moveable relative to the central body such that a portion of the extendable member is configured to move from a retracted position relative to the axis of the elongate central body to an extended position where the portion of the extendable member extends laterally beyond the central body. The lead includes a first electrode disposed on the central body and second and third electrodes disposed on the extendable member. The lead is configured such that the centers of the first, second and third electrodes are linearly arranged when the extendable member is in the extended position.

11. A method for providing therapy to a targeted tissue of a patient comprising:
-
inserting a conduit having a central lumen into a patient; implanting a lead into the patient by passing it through the central lumen of the conduit, the lead having an elongate central body with a first electrode thereon and a first extendable member having second and third electrodes thereon, the extendable member capable of pivoting relative to the elongate central body from a retracted position to a laterally extended position; deploying the extendable member to the extended position to form an electrode array in which the geometric centers of the first, second and third electrodes are linearly arranged; coupling a proximal end of the lead to a therapy delivery device; and operating the therapy delivery device to provide treatment therapy though the electrode array. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system comprising:
-
a moveable stylet having a driver; and an implantable medical lead comprising (i) an elongate central body having an axis; (ii) a first extendable member pivotably moveable relative to the central body such that a portion of the extendable member is configured to move from a retracted position relative to the axis of the elongate central body to an extended position where the portion of the extendable member extends laterally beyond the central body; (iii) a first electrode disposed on the central body; and (iv) second and third electrodes disposed on the extendable member, wherein the first, second and third electrodes each have a center, wherein the centers of the first, second and third electrodes are linearly arranged when the extendable member is in the extended position, and wherein the first extendable member includes an actuation surface configured to interact with the driver of the movable stylet to cause the first extendable member to move from its retracted position to its extended position by pushing on the stylet when the driver is engaged with the actuation surface. - View Dependent Claims (19, 20)
