An everting balloon catheter having a distal end opening defined by a beveled rim is disclosed. The distal end portion of a catheter, e.g. an everting balloon catheter can, be made radioopaque by bonding a distal end portion comprising a polymeric material doped with a mayor amount of radioopaque metals onto a catheter body. Alternately a composition, comprising polymeric adhesives and/or precursors of polymeric, adhesives and a mayor amount of radioopaque metal components can be placed, e.g. painted, on the distal end portion of a catheter body to provide the desired degree of radioapacity.

Why it's free to use
- Filed June 22, 1990 and granted August 21, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 22, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 22, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
