Claims8
A method for preventing contrast-induced nephropathy during an imaging procedure, comprising the steps of:
- a) inserting a first catheter containing a first inflatable balloon at a first catheter distal end in a patient's right renal artery;
- b) inserting a second catheter containing a second inflatable balloon at a second catheter distal end in the patient's left renal artery;
- c) inflating each inflatable balloon to block the flow of blood from the patient's blood circulation to the patient's kidneys;
- d) introducing contrast media into the patient's blood circulation;
- e) performing the imaging procedure;
- f) deflating each inflatable balloon;
- and
- g) removing each catheter from the patient.
