CE Mark for Percutaneous CLI System

Critical Limb Ischemia (CLI) specialist LimFlow SA has gained CE Mark approval for its fully percutaneous LimFlow System designed for venous arterialization of the lower limbs in end-stage patients at risk of limb amputation.

Background

A recent visitor to our pages with the news of its new CEO, LimFlow is a beneficiary of the MD Start European Medical Device incubation and management accelerator.

CLI is the most severe form of peripheral artery disease (PAD) and often occurs in patients suffering from coronary artery disease, diabetes, obesity, high cholesterol and high blood pressure, many of which are growing health problems. Patients with CLI often experience profound, chronic pain and develop festering wounds or infections that lead to major limb amputation, an event closely associated with increased mortality and reduced quality of life.

To relieve the symptoms of CLI, appropriate patients are treated with Percutaneous Transluminal Angioplasty (PTA) or with open and complex Distal Bypass Surgery (DBS). However, in many late-stage patients, neither option is feasible due to extensive disease in the target arteries or other anatomical constraints. This is where the LimFlow system steps finds its place. It’s a novel percutaneous therapy for patients who have exhausted all current revascularization options, designed to promote chronic wound healing and avoid major amputation. The system uses proprietary ultrasound-guided catheters and covered nitinol stents to uniquely bypass diseased arteries and divert blood flow into the tibial vein in order to vascularize the entire ischemic foot.

First-in-Man and CE Mark clinical studies have been completed for the LimFlow System. The initial clinical results have been presented at the Amputation Prevention Symposium (AMP) and the Vascular International Advances Annual Conference (VIVA), and journal publication of these results is expected soon.

Physician comments

“Due to the ongoing epidemic of diabetes and cardiovascular disease, every year more and more patients are presenting with end-stage CLI, and the tools we have to treat them are limited,” said Steven Kum, MD, vascular surgeon at Changi Hospital in Singapore. “The LimFlow System is a new and critically important option for patients who suffer substantially from their ischemic foot. This therapy will create a strong foundation for us as vascular specialists, working with a wound care team, to provide new hope for them.”

Company comments

“Utilizing the existing alternative pathway of the venous vasculature, the LimFlow System is designed to reestablish perfusion for patients that have chronic, non-healing wounds and are in imminent danger of losing a limb,” said Dan Rose, chief executive officer of LimFlow. “We can now provide an option for patients that have none today. In early clinical cases, we have seen patients with extensive and severe foot wounds, including gangrene, fully heal following treatment with the LimFlow therapy, becoming mobile and active again.”
