Patent number: 7960498Abstract: An embodiment of the invention is a water soluble chain-extended polyamine product made by a process comprising reacting a multi-arm polyether amine with a bifunctional crosslinker of the formula: X1—R—X2. Another embodiment is a water soluble chain-extended polyamine product made by a process comprising reacting a multi-arm polyether having at least three arms and three electrophilic endgroups with a primary diamine crosslinker of the formula: NH2—R2—NH2, followed by treating of the chain-extended product so as to convert the remaining electrophilic endgroups to amine endgroups. Crosslinking of the chain-extended polyamine products with an oxidized polysaccharide provides useful tissue adhesives with modified elasticity, that provides greater compliance to underlying tissue, and improved stability in aqueous environments.Type: GrantFiled: June 21, 2007Date of Patent: June 14, 2011Assignee: Actamax Surgical Materials, LLCInventors: Henry Keith Chenault, Garret D.

Patent number: 7960439Abstract: The invention relates to oligomers of cholic acid, cholate derivatives and amino acids called “foldamers” that undergo conformational changes in response to changes in temperature, solvent polarity, small molecules, metal ions, and pH. The foldamers can be used in self-assembling monolayers, or as environmental probes to detect changes in the environment, or as protective agents useful for protecting labile materials from the environment, or as a controlled delivery system for delivering drugs and other useful agents to specific in vivo or in vitro sites.Type: GrantFiled: June 12, 2007Date of Patent: June 14, 2011Assignee: Iowa State University Research Foundation, Inc.Inventor: Yan Zhao
