Patent number: 8784476Abstract: An expandable balloon for insertion in a fluid conduit of a human or animal body is movable between a collapsed condition and an expanded condition. The balloon has, when in the expanded condition, a center line which follows a substantially helical path. The balloon can be combined with a stent such that the stent is expandable by the balloon from a collapsed condition to an expanded condition.Type: GrantFiled: March 3, 2009Date of Patent: July 22, 2014Assignee: Veryan Medical LimitedInventors: Colin G. Caro, Nicholas V. Watkins, Brian G. Falzon, Philip L. Birch

Patent number: 8226704Abstract: A stent for insertion in a fluid conduit of a human or animal body when the stent is in a collapsed condition and for expansion to an expanded condition, includes an outer wall for engagement with the conduit. The outer wall has a helical portion which in the expanded condition extends longitudinally and circumferentially, and which, upon expansion of the stent from the collapsed condition to the expanded condition, resists extension.Type: GrantFiled: March 18, 2004Date of Patent: July 24, 2012Assignee: Veryan Medical LimitedInventors: Colin G. Caro, Nicholas V. Watkins, Brian G. Falzon, Philip L. Birch

Patent number: 8088345Abstract: The present invention relates to piping (1) for use in industrial activities, where the piping (1) has a specific geometry. In particular, the piping (1) is formed as a lowamplitude helix, which causes fluid flowing through the piping (1) to swirl. This swirl flow provides a large number of advantages. Particular applications where the piping (1) can be used include petroleum production risers and flowlines, production tubing for downhole use in wells, pipelines for the transportation of fluids, static mixers, bends, junctions or the like, penstocks and draft tubes, reactors for chemical, petrochemical, and pharmaceutical applications, heat exchangers, cold boxes, incinerators and furnaces for waste disposal, static separators, and air intakes.Type: GrantFiled: September 21, 2005Date of Patent: January 3, 2012Assignee: Technip France S.A.S.Inventors: Colin G. Caro, Philip L. Birch, William Tallis

Patent number: 8029749Abstract: The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centerline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix.Type: GrantFiled: September 19, 2008Date of Patent: October 4, 2011Assignee: Technip France S.A.S.Inventors: Colin G. Caro, Philip L. Birch, William Tallis

Patent number: 7749462Abstract: The invention relates to piping for use as a pyrolysis tube in a cracking furnace. The tube is formed such that it has at least one section whose centreline curves in three dimensions, to induce swirl flow in the tube. Preferably, the tube is formed as a helix, more preferably a low-amplitude helix.Type: GrantFiled: March 15, 2007Date of Patent: July 6, 2010Assignee: Technip France S.A.S.Inventors: Colin G. Caro, Philip L. Birch, William Tallis

Publication number: 20090044954Abstract: A method of transporting multiphase fluids during extraction of said fluids from a well. The method includes first providing a well production apparatus. The well production apparatus includes tubing for carrying a flow of well production fluids. A centre line of the tubing follows a substantially helical path, and the amplitude of the helix is less than or equal to one half of the internal diameter of the tubing. Then, the method includes transporting multiphase fluids along the tubing whilst inducing swirl flow thereof.Type: ApplicationFiled: October 1, 2008Publication date: February 19, 2009Inventors: Colin G. Caro, Nicholas V. Watkins, Philip L. Birch
