Abstract
The present invention provides a method, system, and apparatus that can substantially reduce the recirculation of venovenous extracorporeal membrane oxygenation (VV ECMO) associated with the two-site, single-lumen cannulation approach. Actively-controlled flow regulators comprising balloon, occluder and reservoir can be individually or collectively equipped on the drainage and/or infusion cannulas to accomplish the goal of maximizing VV ECMO support efficacy. Three specific embodiments are introduced to illustrate the practical enforcement of the proposed blood flow control in reference to the heart rhythm, aiming at achieving the maximal reduction of oxygenated blood flow recirculating back to the VV ECMO circuit.
