A medical retriever device is used to retrieve and/or fragment stones (and/or other objects) from the body of a patient. The device has a retrieval basket with a releasable tip.

Why it's free to use
- Filed January 7, 2002 and granted June 19, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 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.
