Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - ReLeaf

Experimental: Treatment - Subject to undergo the ReLeaf study procedure.


Treatment: Devices: ReLeaf
The ReLeaf catheter is expected to enable a physician to create tissue leaflets that, in turn, generate a valve effect in the deep veins of the legs.

Eligibility
Key inclusion criteria
* History of symptomatic chronic venous insufficiency subjects, clinical category CEAP 3 or greater.
* History of failed compression therapy (of at least 6 months), combined with superficial venous or perforator surgery.
* Femoral and/or popliteal venous reflux of = 1.0 seconds.
* Deep system reflux with Kistner classification grade 2 or higher.
* 18 years of age or older at the time of consent.
* Willing and able to sign the Ethics Committee (EC) approved informed consent form.
* Willing to comply with follow-up evaluations and protocols.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* In the Investigator's opinion, venous outflow obstruction that would inhibit adequate flow away from valve site.
* Obstructive features in the femoral or popliteal vein below the proposed tissue leaflet creation site, which, in the Investigator's opinion, will not allow for sufficient blood flow to the tissue leaflet creation site.
* Deep venous system intervention within 6 months of consent.
* Obstructive features or irregularly small luminal diameter in the femoral vein which, in the opinion of the Investigator, will prohibit access to a tissue leaflet creation site.
* Prior deep vein valve surgical intervention in the ipsilateral limb.
* Ankle arthrodesis with secondary muscle atrophy or severely limited ambulation.
* Limb-threatening circulatory compromise.
* Contraindications to anticoagulation therapy that cannot be medically controlled.
* History of symptomatic pulmonary embolism.
* Acute venous thromboembolism within 3 months of consent.
* Comorbidity risks which, in the opinion of the Investigator, limit longevity or likelihood of complying with protocol follow up.
* General contraindications to surgery or the use of anesthesia.
* Uncontrolled heart failure, or NYHA Class III or IV heart failure.
* Open Cardiac surgery (e.g. ventriculotomy, atriotomy) within the past 6 months of consent (Interventional procedures such as stenting or PTCA do not apply.)
* Chronic Kidney Disease with creatinine level of 2mg/dL or higher.
* Active systemic infection or sepsis.
* Pregnant or lactating (positive pregnancy test, women of childbearing potential must be tested).
* Appropriate vascular access is precluded.
* Subject is enrolled in any other clinical study that, in the opinion of the Investigator, may conflict with this study or compromise study results.
* Subject is considered at high risk for non-compliance with the protocol (e.g., inaccessible for follow-up).
* Other invasive surgical procedure within the last 90 days that in the Investigator's opinion would interfere with the study procedure or results.
* History of stroke within the last 6 months.
* Subject is incarcerated or will be incarcerated during the course of the study.
* Untreated significant superficial venous incompetence
