A 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
See the Spiral Flow™ Vascular Graft Instructions for Use for additional information on working with the Spiral Flow™ Vascular Access Graft.
