A lead anchor includes a body with opposing first and second major surfaces and at least one edge surface between the first and second major surfaces. The body defines a first channel, a second channel, and a notch. The first channel extends from the edge surface of the body and is open at the first major surface. The second channel extends from the edge surface of the body and is open at the second major surface. The notch extends from the edge surface of the body, defines an opening from the first major surface through the body to the second major surface, and intersects the first channel and the second channel. The first channel, the second channel, and a portion of the notch define a passage through the body so that a lead can be inserted into the notch and turned to dispose a portion of the lead within the passage. The lead anchor can be part of a kit or system that also includes a lead.
