Positive results from Limflow SA’s PROMISE II U.S. pivotal trial show its Limflow system for transcatheter arterialization of deep veins (TADV) led to sustained amputation-free survival and wound healing in patients with chronic limb-threatening ischemia (CLTI), a severe form of peripheral artery disease. According to the Paris-based company, 76% of CLTI patients who received Limflow therapy were able to avoid an otherwise life-saving major amputation.
