Open the CIPO recordAbstract From the Canadian patent
An apparatus (430) for closing a vascular wound includes an apparatus that can be threaded over a guidewire(458) into place at or adjacent the wound. The apparatus includes a chamber(520) that encloses a hemostatic material (270) therein. When the apparatus is positioned adjacent the wound as desired the hemostatic material is deployed from the chamber. Blood contacts the hemostatic material and blood clotting preferably is facilitated by a hemostatic agent within the material. Thus the vascular puncture wound is sealed by blood clot formation.

Why it's free to use
- Filed August 16, 2004 and granted February 24, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 16, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 16, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
