A cardiovascular catheter for use particularly in open heart surgery and related operations requiring varying forms of cardio-pulmonary bypass. The catheter has a fixed ring provided on the catheter proximal to drainage inlets and may have a sliding ring snug fit on the catheter proximal to the fixed ring for securing the catheter to a penetrated portion of the anatomy, such as the heart wall, between the two rings to assist in holding the catheter in place. In one form of the invention, the fixed ring is used alone to secure the catheter in place, for instance, during a drainage or perfusion application.
