Dialysis grafts
HeRO
by Merit Medical Systems, Inc.
An implanted device designed to provide a passage for blood to flow between an artery typically located in an arm, and a peripheral vein, central vein or right atrium, creating a graft fistula that provides blood access for external procedures, especially haemodialysis. It is a synthetic vascular graft/graft assembly with a thin wall and appropriate size (commonly 6 mm diameter) and configuration to facilitate vessel puncturing. It is typically used when it is not possible or convenient to create a direct arteriovenous fistula or for patients who have exhausted peripheral venous access. Disposable devices associated with implantation may be included.
