A method of anchoring a support material to tissue includes forming an incision in a urogenital triangle of a patient for access to a pelvis of the patient inserting a body portion of an anchor into a lumen in a cannula and having a spine portion of the anchor extending radially out of a wall of the cannula and inserting a leading end of the cannula and the anchor into the incision. The method includes pushing the leading end of the cannula into periosteum tissue of the pelvis engaging the spine portion of the anchor with the periosteum tissue withdrawing the leading end of the cannula from the incision and leaving the anchor engaged in the periosteum tissue and securing the support material to a suture that is attached to the anchor. The method includes delivering the support material through the incision to the pelvis.
