Are you facing amputation
of your leg or foot?

Chronic Limb-Threatening Ischemia (CLTI) is the most severe form of peripheral arterial disease (PAD). It cuts off blood flow to the lower leg and foot, resulting in severe leg pain, wounds that won’t heal and, ultimately, amputation.

If you are facing amputation due to CLTI, the PROMISE II study may offer you a treatment option.

U.S. PROMISE II Clinical Trial

About the Trial

The PROMISE II Trial is studying whether an investigational, minimally-invasive medical procedure that avoids major surgery can prevent foot or lower leg amputation and promote wound healing.

People with the following criteria may qualify to participate in the study:

  • Adult patient
  • May or may not have been diagnosed with Chronic Limb-Threatening Ischemia
  • Severe leg pain, even when at rest
  • Foot ulcers that are not healing
  • Doctor’s recommendation to consider amputation of the foot or leg
  • Not eligible for further conventional endovascular or surgical treatments to resolve artery blockage or CLTI
