The apparatus includes a device for centrifuging the plasma and the agent within the chamber to a degree sufficient for separating the fibrin polymer from the plasma, depositing the polymer on the outer wall of the chamber and expelling the remaining plasma from the chamber.

Why it's free to use
- Filed January 8, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 8, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 8, 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.
