Abstract
A catheter balloon arrangement for application in tortuous blood vessels. First and second spiraled balloons are coupled to a catheter body portion. The spiraled balloons can have first and second apexes with a pitch length there between configured to encourage tortuous compatibility between the catheter balloon arrangement and a body lumen. A method of treatment with an embodiment of a catheter balloon arrangement is also provided.
