1. A method of making a lead, comprising:
- providing a plurality of electrodes including a first electrode, wherein the first electrode comprises a top portion, a bottom portion, and a sidewall portion extending from the top portion to the bottom portion, the first electrode defining at least one opening, wherein the sidewall portion of the first electrode defines the at least one opening; and
in a single molding operation, molding a homogeneous non-conductive material around the plurality of electrodes to form a portion of a paddle body with the non-conductive material holding the plurality of electrodes together, wherein a portion of the non-conductive material flows into and through the at least one opening of the first electrode, a portion of the non-conductive material defines at least a top surface of the paddle body, and a portion of the non-conductive material extends from the top surface of the paddle body through the at least one opening of the first electrode.

Abstract
A lead has a paddle body with a non-conductive material and multiple electrodes disposed within the non-conductive material. At least one of the electrodes includes one or more anchoring arrangement, such as opening(s) through the electrode through which the non-conductive material can pass; anchors that extend away from the electrode and into the non-conductive material of the paddle body; or flow-through anchors attached to the electrode with an opening through which the non-conductive material may pass.

10. A method of making a lead, comprising:
-
providing a plurality of electrodes including a first electrode, wherein the first electrode comprises a top surface, a first elongated side, a second elongated side opposite the first elongated side, shorter third and fourth rounded sides that extend between the first and second elongated sides, wherein the first electrode comprises a top portion, a bottom portion opposite the top portion, and a sidewall portion extending from the top portion to the bottom portion, and wherein the top portion defines a bottom surface of the top portion that is surrounded by the sidewall portion, wherein one or more flow-through anchors are disposed on the bottom surface of the top portion of the first electrode and at least one anchor that extends away from the first elongated side or the second elongated side of the first electrode in a direction that is parallel to the top surface of the first electrode, wherein the at least one anchor has a lateral width that is substantially less than a lateral width of the first or second elongated side from which it extends; and molding a homogeneous non-conductive material around the plurality of electrodes to form a paddle body with a portion of the non-conductive material surrounding the at least one anchor. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
