Abstract:
1. A method of intraluminally positioning an elongate treatment device proximate to a junction in a hollow anatomical structure comprising veins of a patient, the method comprising the steps of: introducing the treatment device into the hollow anatomical structure, the treatment device comprising an elongate shaft and an electrically driven energy application device at a working end of the shaft; identifying the junction where two veins intersect in the hollow anatomical structure by emitting light via a fiber optic device positioned in the hollow anatomical structure; positioning the working end of the treatment device proximate the junction identified in the step of identifying; applying energy to one of the veins in the hollow anatomical structure proximate the junction via the energy application device so as to reduce the diameter of that vein in the hollow anatomical structure.
