Bioadhesives and Hydrogels

Owner Name: CATI - Center for Advanced Technology and Innovation
Category: Medical Device

CATI owns patents and know-how covering bioadhesives including swellable bioadhesive hydrogels, which can be prepared as a thin, clear, tacky layer on an inert substrate, making it particularly useful in biomedical products. Swelling and tackiness can be controlled by varying the composition.

US Patent Number. 6,583,225, Issued 06/24/03, "Polymeric Hydrogels"

The compositions have properties that would be expected of this class of materials. That is, they are smooth, cloudy and clear depending on thickness, purity of precursors, cohesive, and have a neutral taste and non-gritty feel. It is noteworthy that the bioadhesive polymers require no metal-ion catalysts for preparation, and that the crosslinking agents can include clycerol and sorbitol amongst many other polyols.
