Another aspect of the invention relates to a method for reducing lung volume in a patient comprising the steps of advancing into a region of a patient's lung via said patient's trachea a multi-lumen catheter lumen through a bronchoscope; and co-administering, through the multi-lumen catheter, a first mixture comprising a first amount of a polymer containing a plurality of pendent hydroxyl groups; a second mixture comprising a second amount of a crosslinker; and a third mixture comprising a third amount of a sclerosing agent; thereby forming a hydrogel in said region. In certain embodiments, the compositions and methods described herein are intended for use in the treatment of patients with emphysema of the lung.Type: ApplicationFiled: September 26, 2007Publication date: February 18, 2010Inventors: Edward P. Ingenito, Alexander Schwarz, Larry W. Tsai

Patent number: 7364859Abstract: Bioelastomers are disclosed for use in methods of binding compounds including immunoassay methods, in biosensors and methods or regenerating biosensors, and in methods for targeting the delivery of a compound to a particular location within an animal subjects. In general, the bioelastomer is conjugated to a binding compound, which is in turn used to bind a compound of interest. For targeted compound delivery, the bioelastomer is conjugated to the compound to be delivered.Type: GrantFiled: July 31, 2002Date of Patent: April 29, 2008Assignee: Duke UniversityInventor: Ashutosh Chilkoti
