Abstract
Methods, devices, systems of resuscitating a patient including accessing an arterial vessel positioning a catheter into the arterial vessel advancing the catheter through the arterial vessel to position it below a vessel supplying blood to a heart and a brain expanding an expandable portion of the catheter to prevent blood from flowing past the expanded portion and infusing a substance retrograde into the artery within the arterial section between the heart and the expanded portion of the catheter.
Claims9
A method of resuscitating a patient consisting of:
- accessing an arterial vessel;
- positioning a catheter into the arterial vessel that supplies blood to a heart and a brain;
- providing a flow of infused blood through the catheter;
- increasing a resistance of fluid flow at a distal end of the catheter such that the flow of infused blood expands an expandable portion of the catheter to prevent arterial blood from flowing past the expanded portion in the arterial vessel;
- and
- reducing the resistance of fluid flow at the distal end of the catheter such that the infused blood exits the distal end of the catheter and the arterial vessel between the heart and the expandable portion of the catheter.
