Medical Functions Of Expanded PTFE

The full name of the expanded material commonly known in the plastic surgery field is expanded polytetrafluoroethylene surgical soft tissue patch, and the English name: expanded polytetrafluoroethylene (e-PTFE) surgical patch. Its chemical structure is a long chain of carbon atoms wrapped by fluorine atoms. Due to its special molecular structure, expanded polytetrafluoroethylene is an artificial material with extremely stable physical and chemical properties. At the same time, through 6 million clinical applications over 40 years, There is no report of clinical rejection after implantation in various parts including artificial blood vessels, artificial dura mater, and heart patch, which fully proves that the material has good biocompatibility.
