Patent number: 9855373Abstract: The present invention relates to an implantable material having at least one external surface grafted with a film including carboxylate and sulfonate functions wherein the film is simultaneously synthesized and grafted directly on the external surface by radical reaction of a bifunctional adhesion primer of Formula (I) or by radical reaction of an adhesion primer and a bifunctional polymerizable monomer of Formula (II). The invention also relates to a process for directly synthesizing and grafting of a film according to the invention onto at least one external surface of an implantable material. The invention further relates to the use of a grafted implantable material for the manufacture of an antiproliferative and/or antibacterial implantable medical device. The invention also relates to compounds of Formula (I) and Formula (II).Type: GrantFiled: June 13, 2014Date of Patent: January 2, 2018Assignees: BIOWINTECH, COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES (CEA)Inventors: Guy Deniau, Cedric Zobrist, Maxime Oudin, Laurent David

Patent number: 9539558Abstract: The present application is directed to a hydrophobic membrane assembly (28) used within a gas-generating apparatus. Hydrogen is separated from the reaction solution by passing through a hydrophobic membrane assembly (28) having a hydrophobic lattice like member (36) disposed within a hydrogen output composite (32) further enhancing the ability of the hydrogen output composite's ability to separate out hydrogen gas and prolonging its useful life.Type: GrantFiled: October 21, 2014Date of Patent: January 10, 2017Assignees: Intelligent Energy Limited, The Commissariat a L'Energie Atomique et Aux Energies Alternatives (CEA)Inventors: Andrew J. Curello, Michael Curello, Constance R. Stepan

Patent number: 9276271Abstract: A fuel cell system (10) with a toggle switch (32) between an ON or OFF position is provided. In the OFF position, gas is purged from the fuel cell. The fuel cell (12) may surround the fuel source (14) with the cathode side of the fuel cell facing the fuel source. Additionally, both the fuel cell (12) and the fuel source (14) may have similar form factor to maximize the available space. Preferably the form factor is substantially an oval shape. The fuel cell system may also have a pressure regulator (26).Type: GrantFiled: December 13, 2011Date of Patent: March 1, 2016Assignees: Intelligent Energy Limited, The Commissariat a L'energie Atomique et Aux Energies Alternatives (CEA)Inventors: Alain Rosenzweig, Kurt Rath, Andrew Curello

Patent number: 9016319Abstract: A compact, reliable, and easily manufacture relief valve capable of resolving pressure issues within a fuel cell system and its components or devices. The relief valve comprises a valve body having a first cap, a valve housing and a center post; and an elastomeric member or sealing member contained within the valve body and being secured to the valve body at one end and forming a seal with the valve body at the other end. The seal opens in response to a threshold pressure being exceeded. In one embodiment, the elastomeric member is secured to the interior of the first cap and/or valve housing and forms a seal with the outer diameter of the center post. The elastomeric member may be supported by a reinforcing member.Type: GrantFiled: October 26, 2010Date of Patent: April 28, 2015Assignees: Societe Bic, The Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA)Inventor: Paul Spahr

Patent number: 8986404Abstract: The present application is directed to gas generators comprising a fuel mixture and a catalyst. The catalyst is contained in a self-regulated reactor or buoy, and selectively opens and closes to produce a gas in accordance with the demand for gas. This fuel mixture is generally a solution formed by dissolving a solid fuel component in a liquid fuel component. The mixing preferably occurs before the first use, and more preferably occurs immediately prior to the first use. The inventive gas generators preferably further comprises a starting mechanism that isolates the solid fuel from the liquid fuel or vice versa before the first use. In one embodiment, the starting mechanism further comprises a catalyst shield mechanism that isolates the catalyst in the reactor or buoy from the liquid and/or the solid fuel prior to the first use.Type: GrantFiled: July 2, 2010Date of Patent: March 24, 2015Assignees: Societe BIC, The Commissariat a l'energie Atomique et aux Energies Alternatives (CEA)Inventors: Alain Rosenzweig, Andrew J.
