Open the CIPO recordAbstract From the Canadian patent
Disclosed are compositions and methods for the facile perfusion of a tissue with active agents following direct intra-tissue injection. Targets may consist of cells, cellular components, and/or extracellular components. The high perfusion efficiency permits high concentrations of active agents to be delivered to tissue targets resulting in high degrees of efficacy and in some instances the production of novel pharmacological activities of an active agent previously unknown or previously unattainable in vivo.

Why it's free to use
- Filed December 31, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 31, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 31, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
