ABSTRACT:
Lavage apparatus including a tube member having a distal end portion and a proximate end, with a primary lumen extending axially through the tube member for flow communication between said distal end portion and the proximate end and secondary lumens extending through the distal end portion, the secondary lumens being mutually radially opposed and disposed at different distances from the distal end of the tube member to assure unobstructed flow and having the first secondary lumen disposed a distance D from the distal end of the tube member, and a radiopaque tip member extending a distance D into the primary lumen to avoid any internal spaces in which fluid may collect, the tip member also having a beveled shoulder for engaging, in compression, the distal end of the tube member to avoid any annular cavity or gaps in which fluid may collect, the tube member also having an elongate axial radiopaque strip intersecting at least the first secondary lumen to enable medical personnel to assure proper placement of the distal end portion.
