    摘要: An endoscopic system includes a sheath having a flexible sheath body. A tip is attached to a distal end of the sheath body. A handle is attached to the proximal end of the sheath body. A steerable section may be provided in the sheath adjacent to the tip. Steering controls may then be provided on the handle for steering the steerable section. Lumens extend from the tip to the handle. The distal end of each lumen is sealed to the tip. Bodily fluids can only enter into the lumens and not other areas within the sheath. In some embodiments, a shapelock assembly has an elongated hollow body positionable within the sheath body. The shapelock body may be switched between generally rigid and flexible conditions. The sheath provides a sterile barrier around the shapelock body. The shapelock assembly can be readily reused and the sheath may be disposable. In other embodiments, the flexible sheath has a composite construction that provides improved torque transmission capabilities.

    摘要: A flexible surgery access and instrument management system includes a base unit and an insertion unit. The base unit provides a platform having a connection mechanism to which the insertion unit is attached. The insertion unit includes an elongated conduit having one or more tubes providing instrument passages, and a connection mechanism adapted to selectively couple with the mating connection mechanism provided on the base unit. The elongated conduit of the insertion unit is preferably steerable. One or more flexible instruments may be inserted through the tubes of the elongated conduit, with the proximal ends of the instruments being attached to the base unit such that the user is able to control and manipulate the instruments.

    摘要: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube disposed within a hydrophilic sheath or liner, and a distal region having an atraumatic tip. The sheath/liner may be disposable to permit reuse of the overtube. Loading devices may be provided for disposing the sheath/liner about the overtube. Tensioning mechanisms may be provided to selectively stiffen the overtube to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument, while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.
