A method of treating urinary incontinence by implanting a transvaginal mid-urethral sling into a person includes engaging an introducer needle with an extension of an implant； advancing the introducer needle and the extension of the implant from a vaginal incision, along a first path posterior to a pubic bone, and through an abdomen of the patient； and disengaging the introducer needle from the extension of the implant and withdrawing the introducer needle backward along the first path from posterior to the pubic bone out of the vaginal incision.
