The barbs are flat, triangular and are coplanar with respect to each other, as well as being in parallel alignment with the axis of the backspan. The surgical fastener is made of bioabsorbable material to eliminate the need for removal. In alternative embodiments the prongs are obliquely oriented and resiliently biased inward for holding adjacent edges of body tissue in close contact. The alternative embodiments can have arm members projecting from a bridge member.

Why it's free to use
- Filed February 21, 1990 and granted November 12, 1996. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 21, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 21, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
