## Indications for use
The HeRO Graft is indicated for end stage renal disease patients on hemodialysis who have exhausted all other access options. These catheter-dependent patients are readily identified using the KDOQI guidelines as patients who: * Have become catheter-dependent or who are approaching catheter dependency (i.e., have exhausted all other access options, such as arteriovenous fistulas and grafts). * Are not candidates for upper extremity fistulas or grafts due to poor venous outflow as determined by a history of previous access failures or venography. * Are failing fistulas or grafts due to poor venous outflow as determined by access failure or venography (e.g. fistula/graft salvage). * Have poor remaining venous access sites for creation of a fistula or graft as determined by ultrasound or venography. * Have a compromised central venous system or central venous stenosis (CVS) as determined by a history of previous access failures, symptomatic CVS (i.e., via arm, neck, or face swelling) or venography. * Are receiving inadequate dialysis clearance (i.e., low Kt/V) via catheters. KDOQI guidelines recommend a minimum Kt/V of 1.4.
