Abstract From the Canadian patent

A cautery catheter is described having an expandable and electrically conductive mesh that can cauterize treatment sites having large effective surface areas. The mesh is composed of interwoven filaments which are aligned with the cautery catheter in an unexpanded state. Reorientation of the filaments of the mesh enables expansion of the mesh. When the expanded mesh contacts the desired treatment area, an electrocautery unit supplies electrical energy to the filaments of expanded mesh to cauterize the treatment site.

Why it's free to use

  • Filed June 8, 2006 and granted January 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 8, 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.
