Torque lock anchor and methods and devices using the anchor

A lead anchor, comprising:

• a body defining a lead lumen having a first opening and a second opening through which a lead can pass through the body and extend beyond the first and second openings outside the body such that the body is configured and arranged to slide along the lead, the body further defining a transverse lumen that intersects the lead lumen;
• a deformable sleeve at least partially disposed within the body and within the lead lumen, the sleeve extending out of at least one of the first opening or the second opening of the body and configured and arranged to receive a portion of the lead and slide along the lead;
• a separate exterior member surrounding and forming a skin around the body so that the body is entirely disposed within the exterior member, the exterior member being formed of a biocompatible material;
• a fastener for anchoring the lead to the body through the transverse lumen by engaging the sleeve to deform the sleeve to close down on a portion of the lead to anchor the lead in the lead anchor, wherein the fastener is a screw and the transverse lumen is configured and arranged to receive the fastener and the transverse lumen is accessible by a tool through a transverse opening in the exterior member to engage the fastener and tighten or loosen the fastener so that the fastener engages or disengages the sleeve;
• and
• at least two suture tabs extending from the exterior member and configured and arranged for receiving a suture to suture the lead anchor to patient tissue.
