TORQUE LOCK ANCHOR AND METHODS AND DEVICES USING THE ANCHOR

摘要

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.

1. 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, wherein 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, wherein the sleeve is configured and arranged to receive a portion of the lead and slide along the lead; a separate exterior member made of a biocompatible material, wherein the body is entirely disposed within the exterior member; and a fastener for anchoring the lead to the body through the transverse lumen by engaging the sleeve to cause the sleeve to close down on a portion of the lead to anchor the lead in the lead anchor, wherein 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.
