Abstract
A solvent dehydrated microbially-derived cellulose material is described for use as an implantable material in general and plastic surgery.
Claims17
A method for preparing an implantable material for medical and surgical applications comprising the steps of:
- a) providing a microbially-derived cellulose;
- b) treating said microbially-derived cellulose to render said cellulose non-pyrogenic;
- c) dehydrating said microbially-derived cellulose in a continuous manner by applying a water-miscible organic solvent selected from the group consisting of methanol, ethanol, propanol, isopropanol, acetone and mixtures thereof to said microbially-derived cellulose;
- and
- d) subsequently removing said solvent.
2 more elements
A method of preserving microbially-derived cellulose for use as a human implantable device comprising
- a) contacting said microbially-derived cellulose with a water-miscible organic solvent selected from the group consisting of methanol, ethanol, propanol, isopropanol, acetone and mixtures thereof thereby dehydrating said microbially-derived cellulose and
- b) removing said solvent at ambient or atmospheric pressure.
