Polyhydroxyacetic ester, also called polyglycolic acid (PGA), has surgically useful mechanical properties as a solid prosthesis, such as reinforcing pins, screws, plates, or cylinders. On implantation, in living mammalian tissue, the polyglycolic acid is absorbed, and replaced by living tissue.

Polyhydroxyacetic ester, also called polyglycolic acid (PGA), has surgically useful mechanical properties. On implantation, in living mammalian tissue, the polyglycolic acid is absorbed, and replaced by living tissue. Sutures, clips and storage pellets having medicaments incorporated therein can be ...

Roy William Roth: Compacted surgical hemostatic felt. American Cyanamid Company, Samuel Branch Walker, February 10, 1976: US03937223 (79 worldwide citation)

Tissue absorbable synthetic polymeric fibers, such as polyglycolic acid, are felted to form a thin mat with at least one, and preferably both, surfaces compacted by contact with a heated embossing surface such as a hot roller. Porosity is reduced but the compacted felt retains its flexibility, and c ...

Edward Emil Schmitt, Martin Epstein: Reducing capillarity of polyglycolic acid sutures. American Cyanamid Company, Samuel Branch Walker, September 28, 1976: US03982543 (76 worldwide citation)

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 pol ...

Arthur Glick: Densified absorbably polyglycolic acid suture braid, and method for preparing same. American Cyanamid Company Stamford CT, Samuel Branch Walker, February 23, 1971: US3565077 (68 worldwide citation)

The densified polyglycolic acid suture braid is characterized by a tightly compacted braid structure, and has a void fraction of up to about 50 percent less than the void fraction of conventionally fabricated nondensified suture braids. The densified braid is prepared by subjecting a nondensified br ...

Arthur Glick, Lester Daniel Chirgwin Jr: Process for extruding green polyglycolic acid sutures and surgical elements. American Cyanamid Company, Samuel Branch Walker, February 15, 1977: US04008303 (46 worldwide citation)

Polyglycolic acid surgical elements, particularly sutures, are colored green to contrast with tissue, blood, and surroundings by extruding while melted the polyglycolic acid and concurrently in an optically homogeneous dispersion, from about 0.03% to 0.5% by weight of 1,4-bis(p-toluidino)-anthraquin ...

Unsymmetrically 3,6-substituted 1,4-dioxane-2,5-diones may be polymerized to give living-tissue absorbable, hydrolytically degradable surgically useful polymers. These polymers have predominantly regular rather than random spacings of side chains, may be stereoregular and tend toward higher crystall ...

Richard Carl Capozza: Spinning and shaping poly-(N-acetyl-D-glucosamine). American Cyanamid Company, Samuel Branch Walker, October 26, 1976: US03988411 (38 worldwide citation)

Poly(N-acetyl-D-glucosamine) is soluble in hexafluoroisopropyl alcohol and hexafluoracetone sesquihydrate. The solutions formed may be wet or dry spun into filaments, or cast into films or solid articles, which may be used as absorbable surgical sutures, or other absorbable surgical elements. Poly(N ...
