A method of treating prolapse of a vagina is provided by placing a reinforcing implant inside of the vagina. The method includes inserting a porous sheet of material inside of the vagina through a natural vaginal opening of the patient. The porous sheet of material is an implantable support that is adapted to integrate with tissue inside of the vagina to reinforce and support at least an apical portion of the vagina. The method includes maintaining the apical portion of the vagina in an anatomically natural position by supporting the porous sheet of material inside of the vagina relative to one of a sacrum and a ligament of the patient.
