HeRO Vascular Access Device

HeRO (Hemodialysis Reliable Outflow) is a fully subcutaneous system that provides reliable, continuous blood flow directly from a target artery to the central venous system and into the heart. HeRO has no venous anastomosis because the tip of the outflow component is located in the mid to upper right atrium. HeRO is FDA classified as a graft, and is cannulated like a conventional ePTFE graft.

Like other specialized ePTFE grafts, HeRO may require periodic maintenance. A percutaneous technique is recommended (e.g., a rheolytic thrombectomy system, balloon maceration, or balloon-assisted aspiration.)

Use of fluoroscopy during any HeRO intervention is strongly recommended. 

Tips for Successful Outcomes

• Percutaneous or surgical technique may be used to declot HeRO. A surgical technique is recommended during the graft incorporation period to avoid risk of seroma or other complications.
• A 90cm thrombectomy tool is required to accommodate the entire length of the HeRO device.
• Administration of drugs such as TPA or urokinase to lyse the thrombus is recommended.
• Thrombus may be soft or gelatinous in nature and is likely to be present throughout the entire device.
• Mechanical/rotational devices (e.g., Trerotola® device) are contraindicated as internal damage to the Venous Outflow Component and connector may occur.

Troubleshooting Thrombosis

• Test for coagulability disorders after repeated clotting episodes.
• After a clotting episode, thoroughly image the inflow artery all the way to the shoulder and throughout the entire HeRO device, including the outflow component tip, to identify root causes.
• Consider prescribing an anticoagulant in patients with repeated clotting episodes.
• During dialysis treatment, closely monitor the patient for hypotensive events. A clinical evaluation of prescribed hypertensive medication may be necessary.
  
• Avoid using fistula clamps after a dialysis session.

INTENDED USE

The HeRO Vascular Access Device is intended for use in maintaining long-term vascular access for chronic hemodialysis patients who have exhausted peripheral venous access sites suitable for fistulas or grafts. See the Instructions for Use manual for full prescribing information.
