Abstract
Non-occluding catheters and methods for delivering energy to a vessel wall without occluding blood flow through the vessel wall are disclosed. In particular, the invention uses an energy distributor connected to an expansion mechanism and a waveguide. The expansion mechanism causes the distributor to come into close proximity with a target region in the vessel wall, while maintaining at least one fluid passageway for blood flow throughout the instrument.
