64. A device for causing dilation of a tubular anatomy comprising:
-
a distal end and a proximate end; an active element comprising a flexible portion expandable between a first, non-expanded state, and a second, expanded state; and an activator for causing expansion of the flexible portion, wherein the flexible portion comprises a plurality of elongate flexible members, each having a first end positioned towards the distal end of the device, and a second end positioned towards the proximate end of the device, and wherein the activator is adapted to cause circumferential movement of the distal end of the device relative to the proximate end of the device.

65. A method of dilating a tubular anatomy, the method comprising:
-
inserting a device for causing dilation of a tubular anatomy into the tubular anatomy to be dilated, wherein the device comprises; an active element comprising a flexible portion expandable between a first, non-expanded state, and a second, expanded state, an activator for causing expansion of the flexible portion, and a pressure sensor operably connected to the flexible portion; causing expansion of the flexible portion; measuring pressure within the tubular anatomy; collapsing the device; and removing the device from the tubular Anatomy.
