Abstract
Apparatus and methods are provided for delivering oxygenated blood to a patient undergoing cardiac surgery using a perfusion catheter having a distal end carrying first and second sealing members. When the perfusion catheter is inserted through an arteriotomy site, the first and second sealing members are disposed to engage opposite surfaces of a thickness of a vessel to apply pressure against the opposite surfaces of the thickness to seal blood perfused into the vessel from leaking through the arteriotomy site. Apparatus for placing the perfusion catheter, and methods of using the apparatus also are provided.
