ABSTRACT:
A balloon-tipped extracorporeal cannula apparatus suitable for use in a cardiac cannulation technique including a first elongated and flexible tube having an open proximal end and a closed distal tip with a plurality of holes near the distal end, an inflatable balloon on the inside wall of the first tube adjacent to and proximal of the holes, and a second flexible tube contacting the balloon for readily inflating and deflating the balloon. When inflated, the balloon completely occludes the lumen of the first tube and extends to a point between the most distal portion and the most proximal portion of the holes near the distal end of the first tube thereby only partially obstructing the holes. In addition, a method for inserting a balloon-tipped extracorporeal cannula during a cardiac cannulation technique comprising filling the lumen of the cannula with fluid, inflating the balloon on the inside wall of the cannula near the holes at its closed distal tip, inserting the distal end of the cannula into the circulatory system of the person through a prepared incision and deflating the balloon thereby allowing fluid to flow between the cannula and the circulatory system.
