Abstract
Apparatus for sclerosing the wall of a varicose vein includes an inner tube having an expandable balloon at its distal end, an intermediate tube slidably disposed over the inner tube and having a fluid outlet at its distal end and a plunger at its proximal end, and an outer tube through which the plunger is movable. Methods of using the apparatus include deploying the inner and intermediate tubes in the vessel to be sclerosed, inflating the balloon, filling the outer tube with sclerosing agent and moving the plunger from the distal end of the outer tube toward the proximal end.
