Pelvic mesh implant, illustration. Inset (upper right) showing an expanded view of the structure of a pelvic mesh (red, lower centre) that has been implanted in the wall of a woman's vagina. This implant is used to strengthen the muscles in the pelvic region, typically to treat conditions such as a prolapsed (fallen) bladder. This can occur after childbirth. Use of such implants has been suspended by the regulatory authorities in some countries after concerns over their long-term use.
