Abstract:
A catheter for applying energy to a wall of a vessel without occluding fluid flow comprising:a hollow elongated instrument having a proximal end and a distal end at least one lumen therethrough, further comprising at least one waveguide disposed within the lumen, the waveguide having a proximal end and a distal end, the proximal end of the waveguide being adapted to receive energy from an energy source;a distributor disposed of at the distal end of the instrument constructed to receive energy from the waveguide and distribute the energy into a target region of a vessel wall; andan expansion mechanism connected to the distributor for expanding the energy distributor at the target region in order to bring the distributor into close proximity with the vessel wall while creating at least one fluid passageway through the distributor.
