Primary Outcome Measures :
  1. Change in arterial blood volume flow in the bypass graft measured by ultrasound. [ Time Frame: 1 day ]
    Measured by ultrasound duplex

Secondary Outcome Measures :
  1. To assess effect on blood flow in the superficial femoral vein [ Time Frame: 1 day ]
    Measured by ultrasound doppler

  2. To assess effect on microcirculation [ Time Frame: 1 day ]
    Measured using laser Doppler flowmetry

  3. To assess effect on pulse wave velocity, cardiac output and stroke volume [ Time Frame: 1 day ]
    Measured using using the Vicorder device.

  4. To assess effect on levels of VEGF, PAI-1 and tPA antigen. [ Time Frame: 1 day ]
    Blood tests and ELISA

  5. To assess the impact of gekoTM device on pain score utilising the McGill Pain score [ Time Frame: 1 day ]
    Validated pain questionnaire

  6. Patient tolerance/ acceptability [ Time Frame: 1 day ]
    Questionnaire using Visual Analogue Scores and Verbal Rating Scores to be completed following removal of geko™ device
