A lead anchor includes an anchor body having an outer surface, a top end, a front side, a first end, and a second end disposed opposite to the first end. The anchor body defines a longitudinal lead lumen extending from the first end of the anchor body to the second end of the anchor body. The lead lumen is configured and arranged to receive a portion of a lead. A transverse lumen extends from the top end of the anchor body and perpendicularly intersects the lead lumen. An adhesive is disposed within a shell. The adhesive and shell are disposed in the transverse lumen of the anchor body and are configured and arranged for fastening the received lead to the lead anchor by piercing the shell to release the adhesive so that the adhesive passes through the transverse lumen into the lead lumen and into contact with the received lead.
