Abstract
A method, device and system for providing a flow of oxygenated perfusion fluid (e.g. oxygenated whole blood) through a balloon angioplasty catheter to perfuse tissues which would normally be deprived of blood flow when the balloon of the angioplasty catheter is inflated. In accordance with the invention, an extracorporeal membrane oxygenation device is fluidly connected to the angioplasty catheter such that oxygenated fluid (e.g. oxygenated whole blood) may be passed through the catheter and caused to exit the catheter distal to the angioplasty balloon. The patient's own blood may be withdrawn, oxygenated by the extracorporeal membrane oxygenation device and subsequently reinfused through the angioplasty catheter. A dual-lumen introducer sheath may be employed for the dual function of a) facilitating insertion of the catheter and b) allowing withdrawal of blood for subsequent oxygenation and reinfusion through the angioplasty catheter.
