We envision a world where every transplantable organ is placed into a perfusion transporter immediately upon recovery from the donor. A growing body of evidence speaks to the benefits of perfusion in kidneys. Others have begun important work in extrarenal organs. But only now are clinical investigators embarking upon landmark science in this field. Our sponsorship of O:PAIRS (Outcomes from Preservation Alternatives in International Renal-transplant Studies) aims to erase any doubt that kidney perfusion is efficacious, cost-efficient, and practical. Preclinical results and clinical trials in the heart, liver, lung, and intestine are soon to follow. Stay tuned to this site for news and information.
