Abstract: Embodiments of the present invention relate to inflatable balloon catheters and methods for deploying an inflatable balloon catheter. For example, one embodiment is directed to a catheter assembly that includes a catheter comprising proximal and distal ends and at least one longitudinal conduit extending between the proximal and distal ends. The catheter assembly also includes an inflatable balloon comprising proximal and distal ends and configured to be at least partially positioned within the longitudinal conduit when the balloon is uninflated. The inflatable balloon is further configured to be inflated when deployed from the conduit such that a diameter of the proximal end of the inflatable balloon remains substantially constant and a diameter of the distal end of the inflatable balloon is variable and capable of at least partially occluding a lumen.
