Arms Assigned Interventions
Experimental: Experimental: Group A Anastomotic Coupler
Device: ROX Anastomotic Coupler System (ACS). The ACS will be used to create an arteriovenous fistula in the iliac region (between the iliac artery and vein).

The percutaneous creation of an arteriovenous fistula.

Detailed Description:
Chronic Obstructive Pulmonary Disease (COPD) is a chronic disease that leads to irreversible changes in the lung structure, but also to systemic changes in the body that can influence the severity of the disease. The irreversible changes to the lungs can be seen in limitations in the pulmonary function. The purpose of this clinical investigation is to evaluate the performance and efficacy of the ROX AC1 on exercise capacity and respiratory quality of life.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of advanced Chronic Obstructive Pulmonary Disease (COPD) must be made on the basis of current findings, medical history and physical examination.
