Abstract
Embodiments of the present invention are directed to a method and apparatus for accurate positioning of a dual balloon catheter. In one embodiment of the present invention, a first balloon provides an anchoring point. In one embodiment, the first balloon has protrusions to help secure its position. In one embodiment, once the first balloon is inflated, it provides a fixed position relative to which a second balloon is accurately positioned in the treatment region. In another embodiment, a second balloon imparts a radial force. In another embodiment, a second balloon imparts an axial force, using the first balloon as an anchor against which the force is applied. The force may be applied in a forward or a backward direction. In yet another embodiment, a second balloon imparts a rotational force, using the first balloon as an anchor against which the force is applied.
