Suture is a material resembling thread that is used to close surgical incisions as well as traumatic lacerations. Although previously made of natural materials such as catgut (sheep's intestines) and silk, modern suture is made out of synthetic materials.
Suture comes in two general types:
- Permanent, designed for permanent repair where the body is unlikely to repair the damage on its own (such as heart surgery)
- Dissolving, where holding the wound together for a short time will allow the body to make the bond permanent in a short period of time (such as small abdominal incisions typical of a laproscopy)
