Patent number: 10327761Abstract: Systems are provided for delivering a suture to close a surgical opening. An elongated deployment member may have at its distal end a retracted counterforce member. The counterforce member may be inserted into the surgical opening and deployed to resist being withdrawn from the opening. A compression member may be slid down the elongated member to compress the tissue to be sutured against the counterforce member. Suture passers loaded with suture ends may be passed through needle tubes within the elongated member to emerge from the elongated member and pierce the tissue to be sutured, then deposit the suture ends with a suture catcher. The suture passers may be withdrawn, leaving the suture ends. The suture catcher may be retracted, retaining the suture ends and the device—elongated member, retracted suture catcher, and retained suture end—may be withdrawn from the surgical opening. The suture may then be completed.Type: GrantFiled: August 11, 2016Date of Patent: June 25, 2019Assignee: Medeon Biodesign, Inc.Inventors: Shih-Wei Ho, Wei-Min Cheng, Hsiao-Wei Tang, I-Ching Wu, Eric Y. Hu, Po-Hua Lee, Shuling Cheng

Publication number: 20180291124Abstract: Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.Type: ApplicationFiled: April 10, 2018Publication date: October 11, 2018Inventors: Emily Baird Anderson, John Dayton Baker, JR., Terri Roxanne Carvagno, Judicael Jacques Chapelet, Wei Min Cheng, Liu Deng, Jacobus Gillis De Hullu, Sebastian Finger, Hubert Hirschlag, Christopher Lee Lester, Wentao Li, Mutombo Joseph Muvundamina, Mark Stanley Pavlin, Fabian Peters, Carla Recker, Christopher Thomas Scilla
