Fig. 1- Polypropylene tapes‘T’ create new collagen (inset) to reinforce the 5 main suspensory structures –pubourethral (PUL), uterosacral (USL), arcus tendineus fasciapelvis (ATFP), Cardinal (CL), and perineal body (PB). Tapes attach ligaments transversely to the skeleton and have very little contact with the vagina, very different from mesh sheets which are placed as a sheet behind the vaginal wall.
Inset Figure from the original experiments in canines show formation of collagenous neoligaments formed by tapes.
