Abstract

Devices and methods useful for delivering tools and/or materials to a surgical site are disclosed. In one embodiment, an accessory device for an endoscope is provided and can include an elongate sheath and an accessory channel. The elongate sheath can be adapted to receive an endoscope therein, and it can include a mating element extending longitudinally between proximal and distal ends thereof. The accessory channel can be adapted to receive a tool therethrough and it can also have a mating element extending between proximal and distal ends thereof and adapted to slidably mate to the mating element formed on the elongate sheath. In certain exemplary embodiments, a distal portion of the accessory channel can be adapted to derail from at least a distal portion of the elongate sheath while a proximal portion of the accessory channel remains mated to a proximal portion of the elongate sheath. In use, the elongate sheath and the accessory channel can each provide a pathway for delivering tools and/or materials to a surgical site. The distal ends of elongate sheath and the accessory channel can be detached and positioned independently of one another to afford improved positioning or placement of the tools and/or materials received therethrough.
