Abstract From the Canadian patent

In accordance with the present invention there is provided an applier for a surgical device and method that provides automated ejection of the device and gives the surgeon use of the applier with one operative control. The applier includes a handle a tube movable relative to the handle, and an ejector shaft driven by a force element for ejecting the device. It may include a cap called a bullet nose or probe tip. The cap may have a tapered distal surface to ease entry into small otomies in tissue. Using a button or knob to move the tube automatically triggers the ejector shaft to eject the device when the tube is in the correct position.

Why it's free to use

  • Filed September 27, 2005 and granted November 25, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 27, 2025.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
