Abstract
The luer adapter of this invention includes a barbed portion having a generally cylindrical distal portion, a generally conical portion, a generally cylindrical portion and a generally outwardly tapered proximal portion. The shape of the barb is substantially the same as the shape of the lumen at the proximal end of a catheter but is slightly larger radially and slightly shorter axially than the proximal portion of the lumen. This ensures that when the barb is inserted into the proximal portion of the lumen the luer adapter is positively locked to the catheter.
