Patent number: 9746402Abstract: The present grip design includes a two-piece clamp with an interior space which forms a mold for the sample material. The two-piece clamp further includes undercut apertures which engage complementary tapered portions of upper and lower grips. The sample material can be poured to fill the mold formed within the two-piece clamp. The interior of the upper and lower grips includes a pattern, such as, but not limited to, a threaded pattern, in order to more firmly engage the sample. The samples may include soft materials, liquids, gels, compounds, powdered or similar materials. The grip may be used in connection with bioreactor or materials testing applications.Type: GrantFiled: July 9, 2015Date of Patent: August 29, 2017Assignee: ILLINOIS TOOL WORKS INC.Inventors: Philippe Levesque, Daniel Minahan, Miles Malone

Patent number: 9410113Abstract: A bioreactor system for growing and conditioning tissue for research and implantation in a human or animal body is disclosed which includes one or more tissue growth chambers for growing and conditioning tissue, each chamber being defined by a housing and providing a fluid culture media cavity which can act as a reservoir. A construct for growing three-dimensional tissues is housed in each tissue growth chamber. Each chamber is connected to a source of pressurized air for applying a controlled pressure to the chamber media cavity. The tissue growth chambers can be mounted on an agitation device such as a shaker system which enhances mass transport within the chamber media cavity. A control system is provided to control the pressure and temperature of the pressurized gas delivered to the chamber media cavity and subsequently to the tissue construct.Type: GrantFiled: October 24, 2008Date of Patent: August 9, 2016Assignee: ST3 Development CorporationInventors: Kent S. Vilendrer, Blaise D. Porter, Philippe Levesque

Patent number: 9321988Abstract: An apparatus and method is described for culturing and conditioning cells on a sample. The apparatus includes a fluid delivery system that transmits gas to a first surface of a sample and transmits liquid to an opposite surface of the sample without transmitting liquid onto the first surface. Further, while culturing cells on the sample, the apparatus enables a constant or variable tension and shear stress applied to the sample. The apparatus may thus, for example, be used to culture cells on an external surface of a tissue construct with air and culture cells underneath the tissue construct with a cell growth media. The fluid delivery system may alternatively transmit liquid cell growth media underneath and on the sides of the tissue construct without flowing onto a designated external surface of the tissue construct.Type: GrantFiled: June 18, 2009Date of Patent: April 26, 2016Assignee: ILLINOIS TOOL WORKS INC.Inventors: Blaise D. Porter, Philippe Levesque, Jacob M. Thibodeau
