Publication number: 20130190449Abstract: This invention relates to a method for the production of graphene oxide and its use in various applications. The invention provides a method for the preparation of graphene oxide which involves treating a mixture of graphene oxide and impurities with a solution of a base. The impurities in the graphene oxide include oxygen-containing species that are associated with it i.e. bound to the graphene oxide but which are not covalently bonded to the graphene. The graphene oxide of the present invention has improved purity relative to the poorly characterised graphene oxide that is produced by existing methods.Type: ApplicationFiled: October 6, 2011Publication date: July 25, 2013Inventors: Ian Kinloch, Robert Young, Jonathan Rourke, Neil R.

Publication number: 20060173535Abstract: A prosthesis for treating a body passage includes a micro-porous tubular element and a support element. The tubular element is formed from a thin-walled sheet having a wall thickness of 25 micrometers or less, preferably a coiled-sheet exhibiting temperature-activated shape memory properties. The mesh pattern includes a plurality of openings in the sheet having a maximum dimension of not more than about 200 micrometers, thereby acting as a filter trapping embolic material while facilitating endothelial growth therethrough. The support element includes a plurality of struts, preferably having a thickness of 100-150 micrometers. The support element is preferably an independent component from the tubular element. Alternatively, the support element may be attached to or integrally formed as part of the tubular element. The tubular and support elements are placed on a catheter in contracted conditions and advanced endoluminally to a treatment location within a body passage.Type: ApplicationFiled: March 2, 2006Publication date: August 3, 2006Inventors: Jonathan Rourke, Yi Yang

Publication number: 20060167467Abstract: A unidirectional handle device for an endoluminal device includes an outer tubular member and an elongate inner member slidably received in the outer tubular member. The unidirectional handle includes a handle member, a needle bearing clutch disposed in the handle member, a control member guide, and shaft rotatable in a single direction disposed within the handle member. The shaft is rotatable in a single direction by its engagement with the needle bearing clutch. The shaft is in rotational engagement with the outer tubular member of the endoluminal device. The outer tubular member is slidable from a distal position to a proximal position when the shaft is rotated in the single direction. The unidirectional handle device provides substantially no backlash of the outer tubular member. In addition, the unidirectional handle device advantageously produces a tension-retaining effect during use.Type: ApplicationFiled: February 14, 2006Publication date: July 27, 2006Inventor: Jonathan Rourke

Publication number: 20050283222Abstract: An apparatus for delivering a stent into a blood vessel includes a sheath having a rounded bullet-shaped distal portion including a plurality of flexible leaflets integrally molded thereto. The stent is disposed in its contracted condition within a lumen of the sheath proximate the distal portion. A bumper is slidably disposed within the lumen that includes a helical compression coil, a bumper element attached to the helical coil including a blunt distal edge for abutting the stent, and an extension element extending distally from the bumper element through the stent and between the leaflets to facilitate introducing the apparatus over a guidewire. The sheath is formed by inserting a bullet into a blunt-ended tube, and inserting the tube into a bullet-shaped bore in a heated die until the tube material is softened and deforms into a rounded bullet shape. Slits are then cut into the distal portion to create the leaflets.Type: ApplicationFiled: August 3, 2005Publication date: December 22, 2005Inventors: Rainier Betelia, Edward Gillis, Jonathan Rourke, Yi Yang
