Abstract

Resorbable polylactide polymer scar tissue reduction barrier membranes and methods of their application are disclosed. The scar-tissue reduction barrier membranes are constructed entirely of polylactide resorbable polymers, which are engineered to be absorbed into the body relatively slowly over time in order to reduce potential negative side effects. The scar tissue reduction barrier membranes are formed to have thicknesses on the order of microns, such as, for example, thicknesses between 10 and 300 microns. The membranes are preshaped with welding flanges and stored in sterile packaging.
