Abstract
Perfusion systems and methods are provided for increasing peripheral blood flow to reduce limb ischemia, in which an extracorporeal pump having a controller, and catheter/tubing set, employed alone or in conjunction with an interventional or circulatory assist device, withdraws blood from a patient's vasculature and reintroduces that blood at another location within the patient's vasculature at a controlled local pressure or flow rate, without interfering with operation of the interventional or circulatory assist device or surgical intervention.
Claims25
A method for perfusing a target region of a patient, the method comprising:
- coupling an inlet of an inlet lumen to a source of blood;
- positioning an outlet of a return lumen in a target area of the patient's vasculature;
- monitoring local blood pressure associated with the target area of the patient's vasculature;
- causing an extracorporeal pump fluidically coupled to an outlet of the inlet lumen and an inlet of the return lumen to enter a local pressure control mode via a controller associated with the extracorporeal pump;
- and
- causing the extracorporeal pump, in the local pressure control mode, to receive blood through the inlet of the inlet lumen and to deliver blood through the outlet of the return lumen to perfuse the target region of the patient at a selected local pressure.
