Abstract:
A cannula for conducting fluid to a body, the cannula comprising:a first cannula body having a proximal end, a distal end, and a lumen extending therebetween, the lumen adapted to receive the fluid flowing therethrough;a first cannula tip coupled to the distal end of the first cannula body and including a side wall having a plurality of fluid outlets formed therein, each of the plurality of fluid outlets being directed toward the proximal end of the first cannula body to reverse the flow of fluid exiting the cannula by an obtuse angle from the original direction of flow; anda second cannula body having a proximal end, a distal end, and a lumen extending therebetween, the lumen being adapted to receive fluid flowing therethrough, the second cannula adhered to a portion of the first cannula body to create a septum separating the lumens of the first and second cannulas, wherein the reinforcement of the lumen of the first cannula body resists deflection of the septum as a result of differing fluid pressure levels inside the lumens wherein the exterior surface opening of a first fluid outlet does not overlap the interior surface opening of any adjacent fluid outlet.
