摘要： A modular cannula for drainage and return of fluids from and to a body, such as the body of a patient, is adjustable to enable an operator to achieve desired flow characteristics during such fluid drainage and return procedures. The modular, dual-lumen cannula system has an outer drainage cannula and an inner return cannula that is moveable with respect to the outer drainage cannula. By enabling movement of the inner return cannula with respect to the outer drainage cannula, a distance between return outlet ports at the distal end of the return cannula and drainage ports at the distal end of the drainage cannula may be manually adjusted. Such adjustable distance allows for optimal positioning of both the drainage and return ports that are particularly adapted to an individual patient’s physiology, in turn enabling optimal fluid flow characteristics to be achieved regardless of that patient physiology.
