  • Reducing capillarity of polyglycolic acid sutures
    Patent number: 3982543
    Abstract: Useful surgical elements consist of a sterile synthetic copolymer containing, by mole percent, about 15 to 85 percent glycolic acid and 85 to 15 percent lactic acid, which has enhanced tissue absorption as compared with polylactic acid and enhanced solubility in organic solvents as compared with polyglycolic acid and hence can be cast into sheets during preparation and implantation. Such surgical element may be used alone or in combination with polyglycolic acid or a coating for polyglycolic acid surgical elements. Other comonomers may be introduced into the system.
