Lead anchors and systems and methods employing the lead anchors

摘要

A lead anchor including a body having a first end and a second end opposite to the first end is disclosed. The body defines a lead lumen extending from the first to the second end and can receive a lead. The lead anchor also includes a fastening mechanism disposed in the body and in communication with the lead lumen. The fastening mechanism can fasten the received lead to the lead anchor when actuated by a user. The lead anchor also includes tabs(s) extending from the body and tags. Each tag includes an anchor attachment element and a cylindrical implantation element coupled to the anchor attachment element. The anchor attachment element is affixed to one of the tabs. The cylindrical implantation element anchors the lead anchor into patient tissue by insertion of the implantation element into the patient tissue using a needle insertion tool.
