20120197028 | Crosslinked Polymers with the Crosslinker as Therapeutic For Sustained Release - Crosslinked polymers, methods for their preparation and use, are described in which the crosslinked polymers are formed from at least two polymer precursors, one of which is designed, upon degradation of the crosslinked polymer, to release the second polymer precursor in its original, unmodified chemical form. | 08-02-2012 |
20130225857 | Crosslinked Polymers with the Crosslinker as Therapeutic for Sustained Release - Crosslinked polymers, methods for their preparation and use, are described in which the crosslinked polymers are formed from at least two polymer precursors, one of which is designed, upon degradation of the crosslinked polymer, to release the second polymer precursor in its original, unmodified chemical form. | 08-29-2013 |
20130323312 | Microspheres Including Oxidized Cellulose - A process for forming microspheres is disclosed. The process includes: forming a first plurality microspheres comprising at least one bioactive agent and modified cellulose; contacting the first plurality of microspheres with a solution of a biodegradable polymer to form a discontinuous phase liquid; contacting the discontinuous phase liquid with a continuous phase liquid to form an emulsion; and extracting a second plurality of microspheres from the emulsion, the second plurality of microspheres comprising the first plurality of microspheres. | 12-05-2013 |
20130323315 | Microspheres Including Oxidized Cellulose - A process for forming microspheres is disclosed. The process includes contacting a solvent with a modified cellulose to form a solution; contacting the modified cellulose solution with at least one bioactive agent to form a discontinuous phase liquid; contacting the discontinuous phase liquid with a continuous phase liquid to form an emulsion; and contacting the emulsion with a third phase liquid to extract the solvent from the emulsion, thereby forming a plurality of modified cellulose microspheres. | 12-05-2013 |
