Zusammenfassung:	The present disclosure is directed to a coaxial cannula assembly including an infusion tube defining a return lumen and having a proximal end and a distal end. The distal end of the infusion tube includes a plurality of infusion openings and a flow restriction member positioned between the plurality of infusion openings and a distal tip of the infusion tube. The cannula assembly also includes a drainage tube co-axially aligned with the infusion tube and having a proximal end and a distal end. The distal end of said drainage tube includes a plurality of drainage openings and a length of the drainage tube is less than a length of the infusion tube. The cannula assembly further includes a drainage lumen defined by a space between said infusion tube and said drainage tube.
