Patent number: 7273910Abstract: Process for the preparation of a functionalized polymer containing an additive, in which process there is formed a compound that contains, besides at least one blocked isocyanate group, a free amino, hydroxy or carboxy group; this compound is linked to an additive via the free amino, hydroxy or carboxy group in the additive; this additive linked to the compound mentioned is contacted with a polymer that contains at least one free amino or hydroxyl group, at a temperature above the polymer's melting point and at least above 150° C., such that the blocked isocyanate group reacts with the free amino or hydroxy group of the polymer to form the functionalized polymer. The invention also relates to the intermediate products formed in the process and in the preparation thereof. Lastly, the invention relates to functionalized polymers and polymer compositions containing the functionalized polymer.Type: GrantFiled: February 20, 2003Date of Patent: September 25, 2007Assignee: DSM IP Assets B.V.Inventors: Jacobus Antonius Loontjens, Bartholomeus Johannes Margretha Plum, Albert Arnold Van Geenen, Weihua Ming

Patent number: 7226978Abstract: The invention provides an implantable membrane for regulating the transport of analytes therethrough that includes a matrix including a first polymer; and a second polymer dispersed throughout the matrix, wherein the second polymer forms a network of microdomains which when hydrated are not observable using photomicroscopy at 400× magnification or less. In one aspect, the homogeneous membrane of the present invention has hydrophilic domains dispersed substantially throughout a hydrophobic matrix to provide an optimum balance between oxygen and glucose transport to an electrochemical glucose sensor.Type: GrantFiled: May 22, 2002Date of Patent: June 5, 2007Assignee: DexCom, Inc.Inventors: Mark A. Tapsak, Rathbun K. Rhodes, Mark C. Shults, Jason D. McClure

Patent number: 7202281Abstract: The present invention relates to a method for reducing adhesions associated with post-operative surgery. The present method comprises administering or affixing a polymeric composition preferably comprising chain extended, coupled or crosslinked polyester/poly(oxyalkylene) ABA triblocks or AB diblocks having favorable EO/LA ratios to a site in the body which has been subjected to trauma, e.g. by surgery, excision or inflammatory disease. In the present invention, the polymeric material provides a barrier to prevent or reduce the extent of adhesions forming.Type: GrantFiled: December 31, 2003Date of Patent: April 10, 2007Assignee: Synthemed, Inc.Inventors: Daniel Cohn, Eli Pines, Anna Hotovely
