    摘要: A first apparatus for cleaning a distal end of a medical scope includes an annular sheath surroundingly attachable to the scope wherein the distal scope end is in fluid communication with the distal end of a lumen of the attached sheath with the proximal lumen end fluidly connectable to an irrigation fluid source and/or vacuum source. A second apparatus includes a motor-driven rotatable cannula having a closed distal end. A third apparatus includes an annular sheath and a lens which closes off the sheath, wherein the scope is insertable into the sheath, and wherein the lens is exposed to a distal lumen end of a lumen of the attached sheath. A fourth apparatus includes an annular sheath and a transparent shield rotatable attachable to the sheath to seal the distal sheath end. A fifth apparatus includes a sleeve attachable to and slidable along a scope.

    摘要: A medical apparatus and method useful for resecting tissue from the gastrointestinal tract are disclosed. The apparatus can include an RF tissue cutting device (20) disposed inward of a side opening (34) in the device. A tissue stop (36) can be used to control the depth of tissue resected, and the tissue stop (36) can include holes for communicating vacuum for drawing tissue into the side opening (34). The tissue stop (36) can be electrically grounded with respect to the RF tissue cutting device (20), and the tissue stop can provide one pole of an RF electrical circuit.

    摘要: Methods and devices are provided for cutting and fastening tissue. In one embodiment, a surgical device can be used to at least partially transect a stomach by not cutting and/or not fastening a portion of tissue engaged in an end effector located at the device's distal end. A portion of the stomach can be engaged by the end effector, and the end effector can be actuated to cut and/or to apply one or more fasteners to tissue engaged in a distal portion of the end effector but not to cut and/or apply fasteners to tissue engaged in a proximal portion of the end effector. In a similar way, the surgical device can be used in any surgical procedure in which it is desired to cut and/or fasten a distal portion of tissue engaged by the end effector but not a proximal portion of tissue engaged by the end effector.
