There are multiple suppliers and distributors of the organ preservation cold storage solutions developed by Drs. Belzer and Southard at the University of Wisconsin. All patents on the formulations used in Belzer UW® Solutions (cold storage solutions and machine perfusion) expired in 2006. Bridge to Life has an exclusive trademark license from the Wisconsin Alumni Research Foundation (WARF) for the trademark Belzer UW®.

In fact, WARF holds an equity position in Bridge to Life Ltd., a WARF startup company. We proudly honor the name of Dr. Belzer and the institution that developed the UW organ preservation solution, which is still the “gold standard” in organ preservation.
