Spiral Flow AV Graft

av access graftA revolution in prosthetic vascular grafts

The graft is a wrapped, expanded polytetrafluoroethylene (ePTFE) graft with custom features injection moulded of Chronoflex polyurethane. The distal portion of the graft contains the patented Spiral Flow™ Inducer, the Inducer Indicator Ring and pre-cut distal anastomotic cuff. The injection moulded components of the graft are NON-REMOVABLE.


The Spiral Flow™ Inducer is an injection moulded component running along the distal end of the graft. It should never be modified as loss of its form may cause Spiral Laminar Flow™ to not be propagated through the graft. See Technical Sheets 200 and 300 for more information on the servicing of the graft.


The Inducer Indicator Ring is palpable to the dialysis staff during graft assessment. NO CANNULATION should occur between the Inducer Indicator Ring and the venous anastomosis. See Technical Sheet 100 for more information on cannulation of the Spiral Flow™ Graft.


Initial cannulation of the Spiral Flow™ Graft should be driven by patient need and availability of other options. Spiral Flow™ Grafts cannulated within 2 weeks of implantation should have post treatment needle hole compression times extended to minimise the risk of bleeding and oozing.


The Spiral Flow™ Vascular Access Graft is handled at implant the same as all other ePTFE grafts. Therefore no technique changes are necessary. It is highly recommended that the distal anastomosis be sewn first to aid in cutting the graft to its proper length.


Once installed, the Spiral Flow™ Vascular Access Graft will create spiral flow immediately. Spiral Laminar Flow™ is easily determined by taking a transverse color Doppler ultrasound over the distal portion of the graft or anastomosed vein. See Technical Sheet 400 for instructions on how to perform the color Doppler ultrasound study.


The process of blockage caused by neointimal hyperplasia in and near the graft-vein anastomosis is driven to a large part by disturbed or turbulent flow. The Spiral Flow™ Vascular Access Graft delivering less turbulent energy by utilising Spiral Laminar Flow™ delivering blood flow into the venous system like a native AV fistula should:

  • Improve device patency
  • Prolong the effective life of devices
  • Reduce downstream disease progression
  • Improve patient quality of life

Spiral Flow™ PV Graft

peripheral vascular graftsA revolution in prosthetic vascular grafts

Our graft is a wrapped, expanded polytetrafluoroethylene (ePTFE) graft with removable external beading over its proximal section. The distal portion of the graft contains the patented Spiral Flow™ Inducer and pre-cut distal anastomotic cuff. Any rings on this segment of the graft are NON-REMOVABLE. The Spiral Flow™ Inducer is an injection molded component running along the distal end of the graft. It should never be modified, as loss of its form may cause Spiral Laminar Flow™ to not be propagated through the graft. See Technical Sheets 200 and 300 for more information on the servicing of the graft. The Spiral Flow™ Peripheral Vascular Graft is handled at implant as are all other ePTFE grafts. Therefore, no technique changes are necessary.


It is highly recommended that the distal anastomosis be sewn first to aid in cutting the graft to its proper length.


Once installed, the Spiral Flow™ Peripheral Vascular Graft will create Spiral Flow™ immediately. Spiral Laminar Flow™ is easily determined by taking a transverse color Doppler ultrasound over the distal portion of the graft or distal artery. See Technical Sheet 400 for instructions on how to perform the color Doppler ultrasound study.


The process of blockage caused by neointimal hyperplasia at graft-artery anastomosis is driven to a large part by disturbed or turbulent flow. The Spiral Flow™ Peripheral Vascular Graft delivering less turbulent energy by utilizing Spiral Laminar Flow™ will;

  • Improve device patency
  • Prolong the effective life of devices
  • Reduce downstream disease progression
  • Improve patient quality of life
