Abstract
A perfusion catheter for use in open heart surgery having an inflatable cuff adjacent the distal end in communication with the lumen of the cathether to self-inflate when perfusion liquid is introduced into the lumen. A reinforcing spine is installed at the cuff area to lend stiffness to the distal end. Flow through passsages in the cuff prevent stagnation and also permit pressure monitoring of the cuff pressure as well as pressure at the distal end of the catheter. An introducer shaft is provided to abut a plug in the lumen, the plug serving to shunt flow through the cuff and also to allow the introducer to apply pressure to the distal end of the catheter when the distal end is being projected into a body organ.
