Aortic catheter and methods for inducing cardioplegic arrest and for selective aortic perfusion

A vascular catheter comprising:

• an elongated catheter shaft configured for introduction into a patient's vasculature, said elongated catheter shaft having a proximal end and a distal end and an inflation lumen extending from said proximal end to an inflation port located on said elongated catheter shaft, and
• an inflatable disk-shaped balloon member mounted on said elongated catheter shaft in fluid communication with said inflation port, said disk-shaped balloon member having a proximal surface and a distal surface and at least one adhesion point between said proximal surface and said distal surface to maintain the disk-shaped geometry of said disk-shaped balloon member when inflated;
• wherein said at least one adhesion point joins a sector of said proximal surface and said distal surface, leaving an inflatable outer toroidal section and at least one radial inflation passage connecting said inflatable outer toroidal section with said inflation port.
