Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The ability to selectively control blood flow through an arteriovenous (AV) graft only when it is needed for dialysis may reduce the current repetitive complications such as thrombosis, venous hypertension post-dialysis bleeding, and blood steal from the extremities. The Hemoaccess Valve System (HVS) allows an AV graft to be turned on to blood flow when it is needed for dialysis then when dialysis is concluded, the device shuts off arterial blood flow and residual blood in the graft is flushed back into the body, using the dialysis blood lines. Once the graft is cleared of blood, the venous valve is then closed. Heparinized sterile saline reside in the graft between dialysis sessions. By having only saline in the graft and restoring normal blood flow to the artery and vein, it is believed that this will dramatically reduce the current complications associated with now having blood diverted through the graft 24/7.
