Abstract From the Canadian patent

Methods and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug are disclosed. The methods and apparatus provide for automatic tamping of the sealing plug. In addition, torque required to tamp the sealing plug is automatically sensed and gear ratios of an automatic tamping device are automatically changed in response to sensed changes in torque. A planetary transmission may be used to automatically change gear ratios in response to the changes in torque.

Why it's free to use

  • Filed April 10, 2006 and granted February 3, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 10, 2026.
  • 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.
