Lead anchor for implantable devices and methods of manufacture and use

A system for stimulation comprising:

• a control module;
• a lead comprising an array of electrodes coupled to the control module;
• and
• at least one lead anchor that may be disposed around a portion of the lead, wherein the lead anchor comprises
• a body having opposing first and second major surfaces and at least one edge surface between the first and second major surfaces, the body defining a first channel, a second channel, and a notch wherein
• 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;
• and
• the first channel, the second channel, and a portion of the notch define a passage through the body wherein the body is configured and arranged so that a lead can be inserted into the notch and turned to dispose a portion of the lead within the passage.

A method of implanting a stimulation device, the method comprising:

• inserting a lead in a notch in a body of a lead anchor;
• and
• turning the lead to dispose a portion of the lead within a passage defined by a portion of the notch, a first channel and a second channel, wherein the first and second channels extend from the notch to an edge surface of the body;
• the first channel is open from a first major surface of the body;
• and the second channel is open from a second major surface of the body, the second major surface being opposite the first major surface.
