Abstract: A surgical stapling device is disclosed which includes a handle assembly, an endoscopic body portion and a tool assembly. The tool assembly is rotatably and pivotally supported on a distal end of the endoscopic body portion. A tool assembly rotation mechanism is provided which includes a rotation knob, a substantially rigid tube and a flexible member interconnecting the rigid tube to the tool assembly. The substantially rigid tube translates rotation of the rotation knob to rotation of the flexible member and provides a channel for passage of other components of the surgical stapling device.

Abstract: A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes.

Abstract: The present invention relates to new delivery systems for cyclopropene compounds of a cyclopropene compound generator comprising at least one substrate, a material containing at least one cyclopropene compound and a release agent whereby at least one side of one substrate is coated with the material containing at least one cyclopropene compound and wherein when the material containing at least one cyclopropene compound is exposed to the release agent, a gaseous cyclopropene compound is released. The present invention also provides methods to release a cyclopropene compound from such a generator to deliver a cyclopropene compound to plants, fruits, flowers or vegetables to inhibit an ethylene response in the plants, fruits, flowers or vegetable.
