Abstract:
1. A method of treating COPD in a patient, said method comprising the steps of: identifying symptoms of COPD; creating an artificial side-to-side fistula via a shunt between an artery and a vein of the patient such that an anatomical fistula of vascular tissue forms and blood flows through the shunt between the artery and vein until a blood plasma oxygen level (PaO evaluating the patient after a stabilization period following creation of the artificial side-to-side fistula, where the stabilization period is sufficient to allow for long-term remodeling of a heart of the patient; adjusting the blood flow through the fistula by restricting flow through another region of the vasculature different from the shunt until the PaO determining an optimum trade-off between a blood level, a cardiac output, and a heart rate of the patient; and operating a flow-mediating device along the artery or vein to control bypass blood flow through the fistula as indicated to treat COPD.
