1. An irrigation device comprising a tubular member having a distal end and a proximal end and at least one bore axially extending from the proximal end to the distal end, the bore terminating at a plurality of orifices which extend at an angle from the bore, anda flared member coaxially positioned with respect to the tubular member, the flared member defining a tip in close proximity to the distal end of the tubular member and a base which is in a spaced apart relationship from the tip of the flared member, the flared member defining a plurality of flared sides extending from the tip to the base, whereby as the flared sides extend from the tip to the base, the flared sides increase in circumference, the flared member defining at least one passageway, the passageway defining at least one open channel adjacent the tip of the flared member and at least one enclosed channel adjacent the base of the flared member, the enclosed channel being defined by the flared sides and the base of the flared member, wherein the bore has a first internal tapered surface having a decreasing circumference as the bore extends toward the distal end of the tubular member, the bore further including at least a second internal tapered surface having a decreasing circumference as the bore extends toward the distal end of the tubular member, whereby the first tapered surface slopes toward the distal end at an angle that is different from a slope of the second tapered surface.
