ABSTRACT:
Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen are described. In one aspect of the invention, a two wire catheter system, of minimal diameter for treating distal arteries is disclosed. In another aspect of the invention, a multiple wire multiple balloon system in disclosed, in which a first balloon on a first catheter is disposed distally of a second balloon on a second associated catheter. Additional balloons and associated catheters may also be incorporated into the multiple wire multiple balloon system. Methods are also discussed for accomplishing sequential dilatations using a multiple wire multiple balloon catheter.
