| 20090004230 | Thermosetting Neutralized Chitosan Composition Forming a Hydrogel, Lyophilizate, and Processes for Producing the Same - The aqueous thermosetting neutralized chitosan composition, forming a phosphate-free transparent hydrogel at a temperature higher than 5° C., comprises 0.1 to 5.0 w/w %, based on the total composition, of a reacetylated chitosan having a molecular weight of not smaller than 100 kDa and a deacetylation degree of 40 to 70%, neutralized with an hydroxylated base, and 1 to 30 w/w %, based on the total composition, of a complexing agent selected from polyoses and polyols derived from polyoses. Said composition is useful for the preparation of an injectable formulation. | 01-01-2009 |
| 20090130176 | INTRAOCULAR LENS WITH DRUG DELIVERY SYSTEM ATTACHED THERETO - The present invention relates to a device comprising an intraocular lens and a drug delivery system attached thereto, wherein said drug delivery system is or can be loaded with one or more therapeutic agents. Preferably, said drug delivery system comprises a biodegradable matrix material wherein said biodegradable matrix material is preferably selected from the group consisting of: poly(lactic acid), poly(glycolic acid), poly(lactide-co-glycolide), polycaprolactones, polyorthoesters, polyanhydrides, polyesteramides and mixtures thereof. Preferred therapeutic agent(s) is/are selected from anti-inflammatory agents, anti-vasoproliferative agents, immunosuppressive agents, antibiotics, antiviral agents, anti-mitotic agents and combinations thereof. Also provided is a method of treatment and/or prevention of one or more diseases or malfunctions of the eye, comprising implanting one, two, three or more devices of the invention into an eye of a patient. | 05-21-2009 |
| 20100113618 | Pseudo-thermosetting neutralized chitosan composition forming a hydrogel and a process for producing the same - The composition disclosed is a pseudo-thermosetting neutralized chitosan composition, neutralized with a hydroxylated base, forming a phosphate-free transparent hydrogel at a temperature higher than 5° C. Said composition contains a homogeneously reacetylated chitosan derived from a chitosan having a deacetylation degree of 80-90%, having a molecular weight of not smaller than 200 kDa and a deacetylation degree of 30-60%, and may further contain a diol. Said composition may be used as a drug delivery system. | 05-06-2010 |
