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.

Abstract: A luminal port assembly insertable into an anatomical passageway includes a housing having a seal which creates a fluid-tight seal between the housing and the tissue of the anatomical passageway. At least one port is provided in the housing. Each port is preferably angularly movable relative to the housing and includes a substantially fluid-tight valved passageway and an insufflation conduit. A mechanism for retaining the luminal port assembly within the anatomical passageway is also provided.
