Open the CIPO recordAbstract From the Canadian patent
A low-profile single-lumen perfusion and fluid delivery balloon catheter for dilatation angioplasty procedures includes a small diameter single-lumen catheter shaft carrying a dilatation balloon adjacent to the distal end thereof. A perfusion conduit is also carried by the catheter shaft and traverses the dilatation balloon to provide perfusion blood flow past the balloon when the latter is inflated. The catheter may be used in mono-rail configuration to facilitate retracing of a subsequent catheter or other therapeutic device along the mono-rail guide wire back to the vascular site under treatment.

Why it's free to use
- Filed October 11, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 11, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 11, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
