Abstract

Systems, methods, and devices are disclosed that permit the use of hyperperfusion, or regional hyperperfusion to targeted areas by the use of an arterial and/or venous access system which allows repeatable, transcutaneous insertion without any need for repeat anesthesia. The systems, methods and devices use various combinations of catheters and/or balloons. Furthermore, systems, methods, and devices are disclosed that permit drugs or other treatment products to be delivered using hyperperfusion, or regional hyperperfusion, to targeted areas by the use of arterial and venous access system and associated catheters and balloons which allow repeatable, transcutaneous insertion without any need for repeat anesthesia.

Claims

1-23. -23. (canceled)

24. A system for providing localized treatment of a patient comprising:

a) one or more access devices having at least one outflow port and at least one inflow port, the one or more access devices being configured to intermittently and recurrently access the patient;

b) one or more occlusion members;

c) one or more external blood modification systems comprising at least one pump;

d) one or more outflow systems providing fluid communication between a blood vessel and the one or more external blood modification systems, through the at least one outflow port;

e) one or more inflow systems providing fluid communication between the one or more external blood modification systems and the same or a different blood vessel through the at least one inflow port.

25. The system according to claim 24, wherein at least one of the one or more occlusion members comprises a movable spatula.

26. The system according to claim 25, wherein a vascular end of the movable spatula is shaped to provide substantially leak proof interaction with the wall of a vessel.

27. The system according to claim 24, wherein at least one of the one or more occlusion members comprises a balloon catheter.

28. The system according to claim 27, wherein the balloon catheter comprises an isolation or occlusive balloon, an inflow or an outflow lumen, at least one pressurization lumen, and at least one pressure transducer lumen.

29. The system according to claim 28, wherein the isolation or occlusive balloon comprises a balloon wall and at least one rigid or semi-rigid support.

30. The system according to claim 24 wherein the external blood modification system further comprises at least one or more additional devices selected from the group consisting of:

pumps, flow controllers, drug delivery devices, blood monitoring devices, blood oxygenators, sampling devices, nutrient suppliers, dialysis or other blood cleaning or scrubbing devices and/or blood temperature control devices.

31. The system according to claim 24, comprising at least two access devices.

32. The system according to claim 24, wherein at least one of the one or more access devices forms a fistula between a vein and an artery.
