  • Resorbable materials based on independently gelling polymers of a single enantiomeric lactide
    Patent number: 5397572
    Abstract: Resorbable materials and their preparation based on gelling a solution of a single polylactide enantiomer. The gel may be dried to produce solid materials, or may be extracted with a nonsolvent prior to drying to make microporous materials. Physical and mechanical properties of the material may be varied by varying the molecular weight of the gelling polymer, or by blending the gelling solution with other polymers or fillers. The resorbable materials can be used to make biodegradable implantation devices.
