Catheter apparatus, and compositions useful for producing same.

摘要

An everting balloon catheter (10) having a distal end opening (59) defined by a beveled rim (56) is disclosed. The distal end portion (22) of a catheter (10), e.g., an everting balloon catheter (10), 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.
