The vision of Access for Life is to facilitate therapies that require repetitive vein access for patients with chronic diseases, with dialysis being the first market to be served. The patented subcutaneously implanted, sensor-enhanced SEAL device preserves vein health while reducing the risk of clinical complications caused by damage to the vessel walls. It provides for the first time, real-time data collection on the dialysis process. The device provides easy and safe catheterization, enabling patients to self-cannulate at home and facilitate clinic-based hemodialysis.
