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 your doctor has suggested amputation of your foot or lower leg to resolve non-healing wounds and pain, the PROMISE III study may offer you a treatment option.

About the Trial

The PROMISE III 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

“There is an epidemic of lower limb amputation due to ischemia in the United States and LimFlow offers a very promising alternative for these patients to potentially heal their wounds and keep their feet.”
