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 vending machine control circuit which at relatively low cost effectively provides a lockout arrangement which ensures the delivery of only one article per money insertion and which allows alternate selection of articles when one selection is stalled or jammed. The circuit arrangement requires only two cam-operated switches per product selection, and has a single credit release relay common to all product selections. The credit release relay is energized when a vend relay is energized as the result of money insertion, and a time delay circuit is provided for maintaining energization of the credit release relay after the vend relay is de-energized near the beginning of a product vend cycle.
