Open the CIPO recordAbstract From the Canadian patent
A large thin walled polyurethane balloon (20) for an intra-aortic balloon pump catheter (10) is coated with a hydrophilic lubricous coating (36) which includes a water-soluble polyvinyl pyrrolidone preferably in a blend with a thermoplastic polyurethane and a suitable, organic solvent and then is dried and cured for a substantial period. The dried and cured balloon (20) is assembled into a catheter (10) and furled. The furled balloon (20f) demonstrates a high degree of slipperiness when hydrated in conjuction with insertion into a patient's vasculature, unfurls readily, and demonstrates flexibility strength and toughness for use in intra-aortic pulsation operation.

Why it's free to use
- Filed December 19, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 19, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 19, 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.
