A lead anchor includes a body having an outer surface, a top end, a front side, a first end, and a second end opposite to the first end. The body defines a lead slot configured and arranged to receive a lead. The lead slot defines an elongated opening extending along the front side of the body from the first end to the second end. A transverse lumen extends from the top end of the body and intersects the lead slot. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener is disposed in the transverse lumen. The fastener is configured and arranged for fastening the received lead to the lead anchor by deforming a portion of the lead.

An insertion assembly for assisting implantation of at least one lead into a patient includes an insertion needle and a sheath. The sheath removably couples with the insertion needle while the insertion needle is being advanced into the patient. When the sheath is coupled to the insertion needle, the sheath is disposed over at least a portion of an outer surface of the insertion needle. The sheath is radially expandable from a non-expanded state to an expanded state that is rigid enough to retract surrounding patient tissue when inserted into the patient. When the sheath is in an expanded state, first and second diameters of the sheath at opposing ends of the sheath are each large enough to concurrently receive at least one of a paddle lead or at least two percutaneous leads.

A lead anchor includes a body defining a lead lumen having a first opening and a second opening through which a lead can pass. The body further defines a transverse lumen that intersects the lead lumen. An exterior member is disposed around at least a portion of the body. The exterior member is formed of a biocompatible material. A fastener anchors the lead to the body through the transverse lumen by deforming a portion of the lead. The transverse lumen is configured and arranged to receive the fastener. At least at least two suture tabs extend from the exterior member and are configured and arranged for receiving a suture to suture the lead anchor to patient tissue.

A device for brain stimulation includes a lead body having a longitudinal surface and a distal end. The device further includes at least one ring array. The at least one ring array includes a plurality of split ring electrodes disposed on the distal end of the lead body. Each of the plurality of split ring electrodes includes a stimulating portion and a base portion coupled to the stimulating portion. The split ring electrodes of the at least one ring array are arranged about the circumference of the lead body. At least a portion of the base portion of at least one of the plurality of split ring electrodes is disposed below, and insulated from, at least a portion of the stimulating portion of another of the plurality of split electrodes.
