A stent comprises a flexible tube having a proximal end, a distal end, and a passageway extending from said proximal end toward said distal end. A first generally straight tube segment extends from the proximal end while a first generally curved segment extends from an end region of the first generally straight tube segment disposed away from the proximal end of the stent. A second generally straight tube segment extends from an end region of the first curved segment away from the first generally straight tube segment and is arranged at an acute angle relative to the first generally straight tube segment. A second generally curved tube segment extends from one end of the second generally straight tube segment and includes a channel on an exterior surface of the second generally curved tube segment. The first generally curved tube segment and the second generally straight tube segment further include at least one cavity irrigation hole extending from the tube passageway, for providing irrigation fluids into the cavity into which the stent is inserted. At least one segment includes a channel on an exterior surface. The channel is sized to serve as a reservoir to contain a predetermined amount of at least one form of medication for delivery, over a period of time, of the medication to a cavity region proximate which the stent has been inserted.La présente invention concerne un tube souple comportant une extrémité proximale, une extrémité distale, et un passage partant de lextrémité proximale en direction de lextrémité distale. Un premier segment de tube généralement droit part de lextrémité proximale alors quun premier segment généralement incurvé part dune région dextrémité du premier segment de tube généralement droit disposé en avant de lextrémité proximale du stent. Un deuxième segment de tube généralement droit, qui part dune région dextrémité du premier segment incurvé en séloignant du premier segment de tube généralement droit, est disposé en angle aigu par rapp
