Abstract:
A fluid delivery device for use in minimally invasive surgical procedures comprising:A) a tubular component having a distal end for insertion into a body cavity; B) a spray tip assembly having a diameter of at most about 12 mm and attached to the distal end of the tubular component for discharging fluid into the body cavity, the spray tip assembly comprising: a first mechanical breakup unit having at least one feed port configured to direct a fluid into a first spin chamber and issue into a first exit port; and a second mechanical breakup unit positioned alongside the first mechanical breakup unit and having at least one feed port configured to direct a fluid into a second spin chamber and issue into a second exit port, wherein the first and second exit ports extend through an external surface of the spray tip; and C) a first fluid source in fluid communication via the tubular component with two first feed conduits for delivering fluid to the first mechanical breakup unit and a second fluid source in fluid communication via the tubular component with two second feed conduits for delivering fluid to the second mechanical breakup unit, wherein the first and second feed conduits deliver fluid to different mechanical breakup units.
