A method of treating urinary incontinence of a patient by introducing a surgical implant through a vaginal incision. The surgical implant includes a suburethral support having first and second suspending members and first and second tissue anchors. The width of each suspending member is less than the width of the suburethral support. Each tissue anchor has a conical tip and is coupled with a respective one of the first and second suspending members. The first and second tissue anchors are inserted into tissue on first and second sides, respectively, of a urethra of the patient without penetrating an abdominal wall. A position of the suburethral support relative to the patient's urethra is adjusted, including pulling the second suspending member through the patient's vagina to adjust the distance between the suburethral support and the second anchor, after which the distance between the suburethral support and the second anchor is fixed.
