Abstract:
1. A high-flow low-pressure irrigation system for directing a fluid to and recovering the fluid from an area within a body, comprising: a sheath defining a sheath lumen with a sheath distal opening at a distal end of the sheath; and a flexible catheter disposed in and through the sheath lumen, said flexible catheter defining a catheter lumen and comprising a plurality of apertures at a distal portion that extends beyond the sheath lumen and spreads in the body area, wherein an irrigation fluid is directed and outputted to the body area through the catheter lumen and the apertures, wherein the distal portion of the flexible catheter is shaped to curve back towards a proximal portion of the flexible catheter and towards the sheath distal opening at the distal end of the sheath in that the fluid outputted from the plurality of apertures at the distal portion of the flexible catheter to the body area is returned through the sheath distal opening at the distal end of the sheath, and wherein the distal portion is shaped into a pigtail configuration.
