1. An apparatus for insertion into the body of a patient comprising:
- a flexible catheter tube sized and adapted to be inserted into the body of a patient;
said catheter tube having a distal end portion and a body portion located proximally of said distal end portion;
said catheter tube including a distal end opening defined by a rim which is beveled; and
balloon means attached to said catheter tube and capable of being inverted in said catheter tube and of being everted therefrom.

Abstract
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 major amount of radioopaque metals onto a catheter body. Alternately, a composition comprising polymeric adhesives, and/or precursors of polymeric adhesives, and a major 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 radioopacity.
