摘要
Therapeutic device (1) for the selective cytoreduction treatment of an obstruction in a natural lumen or passage (2) of the human or animal body, wherein said lumen is obstructed by the localised proliferation of cells, and said device comprises a normally cylindrical tubular element (3) to be located within said natural lumen, which is flexible enough to conform to said natural lumen but rigid enough to provide an artificial channel (4) within said lumen. The tubular element (3) supports lengthwise a medicinal sleeve (7) for registration and engagement with said obstruction once the tube has been located, and arranged for local delivery, at least in its outer surface portion, of one or more cytoreduction, in particular cytotoxic, therapeutic agents, by contacting the cells obstructing said lumen (2).
