<unk>  made of polypropylene, used for inguinal hernia.<unk>  is a loosely woven sheet which is used as either a permanent or temporary support for organs and other tissues during surgery.<unk>  is created from both inorganic and biological materials and is used in a variety of surgeries. Though hernia repair surgery is the most common application, it can also be used for reconstructive work, such as in pelvic organ prolapse. Permanent<unk> es remain in the body, whereas temporary ones dissolve over time. One temporary<unk>  was shown in 2012 to fully dissolve after three years in a scientific trial on sheep. Some types of<unk>  combine permanent and temporary<unk> es which includes both resorbable vicryl, made from polyglycolic acid, and prolene, a non-resorbable polypropylene. Data of mechanical and biological behaviors of<unk>  in vivo may not always be reflective of conditions within the human body due to testing in non-human organisms. Most published reports experiment on mice, thus creating the likelihood of possible differences when inserted into the human body. Also, most published research reports reference<unk> es that are currently disallowed from the medical device market due to complications post-surgery. Additionally, the absence of FDA-approved regulatory protocols and universal standard operating procedures leads to a variety of different testing methods from researcher to researcher. Experimentation may find differing outcomes for some<unk> es.
