Abstract
Intravascular catheter devices and methods for using the same are disclosed. An expandable portion is connected to a flexible catheter tube. A sleeve extends within the expandable portion. The expandable portion includes a number of struts, each of which hinges relative to the flexible catheter tube and the sleeve, and each of which has an intermediate joining portion which permits hinging movement of a first intermediate portion relative to a second intermediate portion upon movement of the sleeve relative to the flexible catheter tube to selectively elevate the intermediate joining portion away from an outer surface of the sleeve. An incising element is oriented to extend along a longitudinal axis of an outer surface of a first intermediate portion of one of the struts for incising vascular tissue.
