A method for treatment of COPD, hypertension, and left ventricular hypertrophy, and chronic hypoxia including creation of an artificial arterio-venous fistula and installation of a flow mediating device proximate the fistula. The flow mediating device is operated to limit flow as medically indicated to provide the optimum amount of bypass flow.

Brenneman, Rodney A. (San Clemente, CA, US); Flaherty, J. Christopher (San Clemente, CA, US)
- Claim:
1. A method of treating COPD in a patient, said method comprising the steps of: creating an artificial fistula between an artery and a vein of the patient; installing a flow mediating device proximate the artificial fistula; operating the flow-mediating device to control bypass blood flow through the fistula as indicated to treat COPD.
- Claim:
2. The method of claim 1 further comprising: operating the flow-mediating device to control bypass blood flow through the fistula to achieve an increase in the patient's PaO2 by at least about 5% as indicated to treat COPD.
- Claim:
3. The method of claim 1 further comprising: operating the flow-mediating device to control bypass blood flow through the fistula to achieve an increase in the patient's SvO2 by at least about 5% as indicated to treat COPD.
- Claim:
4. The method of claim 1 further comprising: operating the flow-mediating device to control bypass blood flow through the fistula to achieve an increase in the patient's cardiac output by at least about 10% as indicated to treat COPD.
- Claim:
5. The method of claim 1 further comprising: evaluating the patient after a stabilization period and adjusting the flow mediating device to control bypass blood flow through the fistula to achieve an increase in the patient's cardiac output by at least about 10%.
- Claim:
6. The method of claim 1 further comprising: providing the flow control device in the form of an inflatable bladder system comprising an inflatable cuff adapted to substantially surround a portion of the patient's vasculature proximate the fistula and means for delivering fluid to the inflatable cuff.
- Claim:
7. The method of claim 1 further comprising: providing the flow control device in the form of an inflatable bladder adapted to impinge upon a portion of the patient's vasculature proximate the fistula and means for delivering fluid to the inflatable bladder.
- Claim:
8. The method of claim 1 further comprising the steps: of providing a band adapted to surround a vessel of the patients vasculature and securing the bladder to the patients vasculature with the band, proximate the fistula.
- Claim:
9. The method of claim 1 further comprising: providing the flow control device in the form of an inflatable bladder adapted to impinge upon a portion of the patient's vasculature proximate the fistula, rigid fastener operably connected to the bladder and means for delivering fluid to the inflatable bladder; and installing the bladder against a portion of the patient's vasculature proximate the fistula and securing the bladder against the portion of the patient's vasculature by placing a portion of the rigid fastener opposite the bladder with the portion of the patient's vasculature disposed between the bladder and the clip, and securing the rigid fastener to the bladder.
- Claim:
10. The method of claim 1 further comprising: providing the flow control device in the form of a shunt or graft between an artery and a nearby vein, and providing throttling means operable to mediate flow through the shunt of graft.
- Claim:
11. The method of claim 10 further comprising: providing the throttling means in the form of a shunt or graft having a lumen and a bladder disposed within the lumen, and inflating the bladder as desired to changed occlude the lumen to the degree necessary to obtain desired bypass flow.
- Claim:
12. The method of claim 10 further comprising: providing the throttling means in the form of a shunt or graft having a lumen and an dissectible wall portion within the lumen, a magnetic mass fixed to the dissectible wall portion, said magnetic mass being operable to deflect the dissectible wall portion when acted upon by a magnet.
- Claim:
13. The method of claim 10 further comprising: providing the throttling means in the form of a shunt or graft having a lumen and compliant sidewalls and a piston 212/637 disposed outside the shunt or graft and means for driving the piston against the sidewall of the shunt or graft to squeeze the shunt or graft to change the size of the lumen; and operating the piston to squeeze or release the shunt or graft as desired to mediate flow through the shunt or graft.
- Claim:
14. The method of claim 1 further comprising: placing the flow mediating device on the vein downstream from the fistula.
- Claim:
15. The method of claim 1 further comprising: placing the flow mediating device on the artery upstream from the fistula.
- Claim:
16. The method of claim 1 further comprising: placing the flow mediating device directly over the fistula.
- Claim:
17. The method of claim 1 further comprising: creating the artificial fistula between a femoral artery and femoral vein of the patient.
- Claim:
18. The method of claim 1 further comprising: creating the artificial fistula between one of the following vein/artery pairs: the aorta and inferior vena cava, the femoral vein and the iliopopliteal vein or iliac vein, the carotid artery and the carotid vein or jugular vein, the brachial artery and brachial vein, and the brachio-cephallic artery and subclavian vein.
