Open the CIPO recordAbstract From the Canadian patent
The invention relates to an automated speed-adaptive and patient-adaptive control scheme and system for a knee prosthesis (110). The control scheme and system utilizes sensory information measured local to the prosthesis (110) to automatically adjust stance and swing phase knee resistances to a particular wearer under a wide variety of locomotory activities. Advantageously no , patient-specific information needs to be pre-programmed into the prosthetic knee (110) by a prosthetist or the patient. The system (110) is able to adapt to various types of disturbances once the patient leaves the prosthetist's facility because it is patient-adaptive and speed-adaptive.

Why it's free to use
- Filed March 29, 2001 and granted December 6, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 29, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 29, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
