HeRO Graft

The HeRO Graft is a fully subcutaneous hybrid vascular access device used for hemodialysis patients with central venous occlusion who cannot receive conventional upper-arm fistulas or grafts. It combines an ePTFE graft with a nitinol-reinforced venous outflow component that bypasses stenosed central veins to the right atrium. Unlike VenoStent's investigational bioabsorbable wrap intended to support maturing fistulas, HeRO is immediately available, surgically implanted, and reimbursed today. It serves a narrower rescue-access population rather than prophylactic support of new fistulas. Long-term data show acceptable patency but higher infection rates than native vessels. Relevance to VenoStent searchers is high when central venous disease precludes standard options.
