Abstract:
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 segments 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.
