  • Valve
    Publication number: 20040117010
    Abstract: There is disclosed a heart valve prosthesis having a configuration such that blood flow through it has a helical flow pattern such as to substantially reduce or eliminate turbulence and dead flow regions in the blood flow.
    Type: Application
    Filed: January 15, 2004
    Publication date: June 17, 2004
    Inventors: Graeme J Houston, Peter A Stonebridge, John Bruce Cameron Dick, Robert Gordon Hood
  • Blood-flow tubing
    Publication number: 20040037986
    Abstract: An artificial or modified natural blood flow tubing has a helical-flow inducer to induce helical flow in such fashion as to eliminate or reduce turbulence. One inducer is a tubular stent of expansible mesh having a helical vane.
    Type: Application

    Publication date: February 26, 2004
    Applicant: Tayside University Hospitals NHS Trust, a British corporation
    Inventors: John Graeme Houston, John Bruce Cameron Dick, Peter Stonebridge
  • Insert for a conduit
    Publication number: 20030139807
    Abstract: There is disclosed an insert (2) for a conduit (4) adapted to effect helical flow in the conduit (4) comprising a longitudinally extending member having a helical formation.
    Type: Application
    Filed: November 21, 2002
    Publication date: July 24, 2003
    Inventors: John Graeme Houston, Peter Arno Stonebridge, John Bruce Cameron Dick, Robert Gordon Hood, Allana Johnstone, Christophe Emmanuel Sarran, Craig McLeod Duff
  • Method for introducing an internal helical formation into a flexible tubular material
    Publication number: 20030120257
    Abstract: There is disclosed a method for introducing a helical formation (11) into a flexible tubular material (12). The material (12) is supported together with a surrounding helical former (13) so as to deform the material (12) to have a helical indentation (11) corresponding to the shape of the former (13). The material (12) is then set in that configuration and the former (13) is removed.
    Type: Application
    Filed: November 20, 2002
    Publication date: June 26, 2003
    Inventors: John Graeme Houston, Peter Arno Stonebridge, John Bruce Cameron Dick, Robert Gordon Hood, Allana Johnstone, Christophe Emmanuel Sarran, Craig McLeod Duff
  • Flow means
    Publication number: 20020179166
    Abstract: There is a disclosed a conduit supporting structure that imposes, maintains and/or reinforces a flow guiding formation of a conduit, whereby to effect a desired flow configuration in the conduit.
