  • Biocompatible porous matrix of bioabsorbable material
    Patent number: 5856367
    Abstract: A process for forming biocompatible porous matrices of bioabsorbable materials comprising:a) providing a bioabsorbable polymer;b) dissolving the bioabsorbable polymer in a volumetric orientation aid to yield a molten solution;c) solidifying the molten solution to yield an orientation matrix comprising first and second phases, the first phase being the bioabsorbable polymer and the second phase being the volumetric orientation aid; andd) removing the volumetric orientation aid while the solution is solid; to yield a biocompatible matrix of bioabsorbable polymer. Also matrices formed by the process and devices made with such matrices.
    Type: Grant
    Filed: December 19, 1995
    Date of Patent: January 5, 1999
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Thomas H. Barrows, Myhanh T. Truong, Paul R. Suszko

  • Process for increasing stability of poly(esteramides)
    Patent number: 5286837
    Abstract: Process for treating poly(esteramides) to improve the heat and storage stability thereof. Polymer is optionally suspended in a liquid medium, treated with an amide group-containing solvent, and then separated from the solvent and liquid medium (if any). Also, poly(esteramides) treated in this process and devices and articles comprising such poly(esteramides).
