Open the CIPO recordAbstract From the Canadian patent
A clip includes a generally U-shaped configuration with first and second parallel arms and a bridge connecting the arms. At least one resilient retainer extends rearward and from at least one of the arms and toward the other arm. During application the clip is forced over compressed tissue. As the clip is forced over the tissue and the tissue enters the space between the arms the retainers are bent by the tissue. The retainer is preferably resilient but may alternatively be plastically deformable. The clip is also provided with structure that facilitates the chaining of a plurality of clips for use in a clip chamber of a clip applier.

Why it's free to use
- Filed March 25, 2004 and granted June 5, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 25, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 25, 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.
