Open the CIPO recordAbstract From the Canadian patent
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.

Why it's free to use
- Filed February 10, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 10, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 10, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
