Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A polymeric liner is arranged for replacement into a wheel well portion of a vehicle for replacement of an original shell lost due to damage and rust. The unitary shell construction permits ease of mounting of the shell structure within an associated vehicle, with the shell having an outer wall formed in a spaced parallel relationship relative to an inner wall, and the outer wall including an outer wall semi-circular recess having a flange orthogonally mounted to the outer wall projecting exteriorly of the shell for ease of mounting to an existing vehicle. The inner wall includes an inner wall recess for accommodating suspension components of an associated vehicle.

Abstract: A first steerable prime mover wheeled tower and a plurality of laterally spaced intermediate and end towers collectively carry a horizontal irrigation conduit which receives water through a hose dragged behind the prime mover wheeled tower. The irrigation conduit is supported by a truss structure extending between the tops of the several towers. Electric drive motors on the individual towers are powered in proper sequence to cause the intermediate and end wheeled towers to follow the linear path of the prime mover wheeled tower without appreciable lag. A system of control switches responds to tension in a control cable connected with a spring-loaded crank element on the prime mover wheeled tower to produce automatic activation of the control switches.
