Systems and methods for the expression of bodily fluid from an incision in the skin include devices which bear against the skin in a manner to retain the fluid adjacent the incision site and urge the fluid inwardly toward the incision. One system utilizes a constricting member (12) which engages the skin at initial, outer positions, and moves to draw the skin into an inner position forming a bulged, pinch of skin (15) containing the incision site (20). The constricting member (12) comprises flexible or non-flexible components, and is formed as a single, continuous member or as a plurality of discrete elements.

Why it's free to use
- Filed June 7, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
