Canadian Invents Device to Help Cystic Fibrosis Patients Breath
Interesting story about a Canadian man suffering from cystic fibrosis who patented a device that helps him breath. His patents for a "chest vibrating device" include US7416536 (B2)
and CA2563723 (C).
Medical devices are a bit more challenging to commercialize because they require the approval of various government agencies. In this case, Health Canada approved the device late last year, almost ten years after the first patent application and four years after the US patent was granted.
I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
