Stent Graft System
LimFlow Stent Graft System for Critical Limb Ischemia
N/A
Recruiting
Led By Daniel Clair, MD
Research Sponsored by LimFlow, Inc.
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial Must have
Clinical diagnosis of chronic limb-threatening ischemia, defined as any of the following clinical assessments: previous angiogram or hemodynamic evidence of severely diminished arterial inflow of the index limb (e.g., ABI ≤ 0.39, TP / TcPO2 < 30 mm Hg) and Rutherford Classification 5, ischemic ulceration or Rutherford Classification 6, ischemic gangrene
Subject has been assessed by the Principal Investigator and determined that no conventional distal bypass, surgical or endovascular therapy for limb salvage is feasible due to either a) absence of a usable pedal artery target (endovascular or surgical approach), or b) the presence of a pedal artery target with absence of a viable single-segment vein in either lower extremity or either arm that could be used for autogenous vein conduit
Must not have
Active infection (e.g., fever, significantly elevated WBC count >20.0 x 109/L, and/or positive blood culture) at the time of the index procedure that may preclude insertion of a prosthesis or require major amputation (e.g., osteomyelitis proximal to metatarsals)
Active immunodeficiency disorder or currently receiving immunosuppressant therapy for an immunodeficiency disorder

Summary
This trial will study how a medical device helps patients with leg artery blockages.
Who is the study for?
This trial is for adults aged 18-95 with severe chronic limb-threatening ischemia, classified as Rutherford 5 or 6, where traditional treatments are not feasible. Candidates must have stable wounds and blood sugar levels (HbA1C <10%), be non-pregnant if of childbearing potential, and able to consent. Exclusions include recent heart attack or stroke, certain kidney diseases, inability to follow the study protocol, severe heart failure, other medical conditions that could interfere with participation, life expectancy under a year, allergies to specific medications or materials used in the procedure.
What is being tested?
The LimFlow Stent Graft System is being tested in this single-arm study across multiple centers. The device aims to create new pathways for blood flow in patients whose limbs are at risk due to poor circulation from peripheral arterial disease.
What are the potential side effects?
Potential side effects may include local complications at the site of stent graft placement such as infection or bleeding; allergic reactions to materials like stainless steel or nitinol; contrast agent reactions; and general risks associated with percutaneous procedures like bruising or clotting.

Eligibility Criteria:
This trial includes the following eligibility criteria:- I have severe leg circulation problems with ulcers or gangrene.Your blood sugar levels are well controlled, with a HbA1C level of less than 10%.The blood vessel near the cross-over point needs to be the right size for the LimFlow stent graft.I am on blood thinners that may affect my safety in the study.I have severe heart failure that might make surgery risky.I do not have an active infection that could interfere with surgery.I have an active immune disorder or am on immunosuppressant therapy.I am allergic to aspirin, certain heart medications, heparin, stainless steel, nitinol, or contrast dyes and cannot be treated for these allergies.I do not have severe leg blood vessel problems that could affect surgery healing.I cannot have standard surgery to save my limb because of specific artery and vein issues.I have been on dialysis for over 6 months, use an AV fistula or peritoneal access, and meet the specified health criteria.I had a surgery to improve blood flow in my leg that might affect a new graft.My target foot lacks enough healthy tissue.The blood vessel where the stent will be placed needs to be the right size based on what the doctors can see.I have had a heart attack or stroke in the last 3 months.I haven't had liver problems, vein inflammation, or bleeding disorders in the last 3 months.My wound is not getting worse and shows signs of healing.My kidney function is poor, with a creatinine level over 2.5 mg/dl, and I am not on dialysis.I am between 18 and 95 years old.You are expected to live for less than a year.
