Patent number: 8617584Abstract: The present invention relates generally to synthetic polymer compositions that form interpenetrating polymer networks. In a preferred embodiment, the compositions comprise two multifunctionally activated synthetic polymers, along with a tensile strength enhancer. Such compositions form matrices that exhibit superior cohesive strength and in many instances can serve as adequate replacements for surgical means of attaching tissues, such as sutures, sponges and medical staples.Type: GrantFiled: May 25, 2010Date of Patent: December 31, 2013Assignee: Angiodevice International GmbHInventors: Louis C. Sehl, Olof Mikael Trollsas, Donald G. Wallace, David Toman, Frank A. DeLustro, Jacqueline A. Schroeder, George H. Chu

Patent number: 7904444Abstract: A method and system for performing a data stream query. A data stream query requiring a join operation on multiple data streams is approximated without performing the join operation. It is determined whether conditions of the query are proper to accurately approximate the join operation, and if the conditions are proper the join operation is approximated. The join operation is approximated by independently aggregating values of the data streams and comparing the independently aggregated values.Type: GrantFiled: April 26, 2006Date of Patent: March 8, 2011Assignee: AT&T Intellectual Property II, L.P.Inventors: Nikolaos Koudas, Divesh Srivastava, David Toman

Patent number: 6653450Abstract: The invention provides recombinant procollagen chains having a natural collagen chain separated from one or two propeptides by one or two non-natural site-specific proteolytic agent (e.g., protease) recognition sites. A wide variety of propeptides and site-specific proteolytic agent recognition sites may be used: the selection of particular site-specific proteolytic agent/recognition site pairs is based on the conformation of the resulting procollagen, the availability of the site-specific proteolytic agent, the compatibility of the proteolysis with production of mature collagen, among other factors. Recombinant collagens chains are produced by contacting the subject recombinant procollagen chains with the appropriate site-specific proteolytic agents. Nucleic acids encoding the subject procollagen chains operably linked to transcription regulatory elements are used in vectors and cells for the production of recombinant collagen.Type: GrantFiled: July 22, 1994Date of Patent: November 25, 2003Assignee: Cohesion Technologies, Inc.Inventors: Richard A.
