Abstract
A method for protecting a kidney in a mammalian patient from an insult including the steps of: at least partially occluding at least one renal vein of the patient; elevating a renal vein blood pressure, and reducing the renal vein blood pressure from the elevated blood pressure
Claims46
A method for protecting a kidney in a mammalian patient from an insult comprising:
- at least partially occluding at least one renal vein of the patient;
- elevating a renal vein blood pressure, and reducing the renal vein blood pressure from the elevated blood pressure.
The method for minimizing radiocontrast nephropathy in a mammalian patient comprising:
- at least partially occluding at least one renal vein of the patient, and
- elevating a renal vein blood pressure during a period during a period coinciding with an injection of contrast in blood of the patient.
The system for treating radiocontrast nephropathy in a mammalian patient comprising:
- a renal catheter further comprising a distal tip section having a renal vein occlusion device and a renal vein pressure detector, and a proximal section external of the patient when the distal tip section is positioned in a renal vein, and
- an actuator for the renal vein occlusion device and connectable to the proximal section of the renal catheter, wherein said actuator controls the renal vein occlusion device.
The system for artificially protecting a kidney during a renal insult in a mammalian patient comprising:
- means for at least partially occluding at least one renal vein of the patient, and
- means for controlling an increase in renal vein blood pressure during a period corresponding to the insult.
The system for artificially protecting a kidney during a renal insult in a mammalian patient comprising:
- a renal catheter further comprising a distal tip section having a renal vein occlusion device and a renal vein pressure detector, and a proximal section external of the patient when the distal tip section is positioned in a renal vein, and
- an actuator for the renal vein occlusion device and connectable to the proximal section of the renal catheter, wherein said actuator controls the renal vein occlusion device.
