| 20120021471 | BIOABSORBABLE POLYMER CONTAINING 2-HYDROXYACID MONOMERS - Genetically engineered organisms for production of PHA copolymers containing 2-hydroxyacid monomers and the methods of making and using thereof have been developed. The copolymers containing 2-hydroxyacid monomers can be synthesized via biosynthesis by the action of a PHA polymerase in a living cell. By changing the genetic background of the cells, one can control specific metabolic pathways allowing control of the level of glycolic acid co-monomer in the PHA polymer. | 01-26-2012 |
| 20100057123 | RECOMBINANT EXPRESSED BIOADSORBABLE POLYHYDROXYALKANOATE MONOFILAMENT AND MULTI-FILAMENTS SELF-RETAINING SUTURES - The present invention provides polymers made by genetically engineering microorganisms for making a self-retaining suture. In an embodiment of the present invention the genetically engineering microorganisms synthesize polyhydroxyalkanoate (PHA) polymers. In an alternate embodiment of the invention, the genetically engineering microorganisms synthesize polybetahydroxybutyrate (PHB) polymers. In an alternative embodiment of the invention, the self-retaining sutures can be made from a copolymer such as polyhydroxybutyratevalerate (PHBV), where the genetically engineering microorganisms produces PHA polymers as the monofilament base material and a different genetically engineering microorganisms produces polyhydroxybutyratevalerate (PHBV) polymers. In various embodiments of the invention, recombinant expressed self-retaining suture materials have a melting point in the range from between approximately 40° C. to approximately 180° C. In various embodiments of the invention, recombinant expressed self-retaining suture materials have extension-to-break strength of between approximately 8% and approximately 42%. | 03-04-2010 |
| 20100003300 | INJECTABLE DELIVERY OF MICROPARTICLES AND COMPOSITIONS THEREFORE - Compositions and methods of making and using of microparticle compositions that provide faster flow or improved injectability through smaller or small-diameter needles have been developed. Notably, the microparticle compositions can be successfully delivered or administered through smaller-diameter needles than other microparticle compositions prepared from biocompatible or biodegradable polymers including, for example, poly(lactide), poly(lactide-co-glycolide), polycaprolactone, or poly-3-hydroxybutyrate. The microparticle compositions can exhibit a higher solids loading for a given needle size and/or faster flow through needles than other microparticle compositions. Further, blending or mixing the polymer of the microparticle composition with other polymer formulations can enhance the injectability of the resulting formulation. | 01-07-2010 |
