Sutures from Bacteria

Sounds icky, but it's true -- the FDA has approved a polymer suture made from modified bacteria using recombinant DNA technology.

The material in Tepha Medical Devices' TephaFLEX Absorbable Suture breaks down in the body as a deep wound or surgical incision heals, improving the healing process and preventing infection. Recombinant DNA allows the manufacture of materials from organisms that would be difficult if not impossible to produce otherwise.
