Systems, apparatuses and methods are described for shuffling a deck, group, stack or pile of cards. The cards are placed into a shuffler. The shuffler may be accessed under a lid, or via a slot or tray. Buttons, switches, or a touch screen and the like serve as an interface to access and control the shuffler. Cards are introduced into a substantially vertical shuffling chute. Cards are counted or audited. Sensors provide information as to the location of the cards. Static barriers and agitators encourage cards to remain in proper orientation and location. An elevator lifts cards from the shuffling chute. Sweeper arms or other mechanism manipulates the cards and returns the cards to a substantially horizontal orientation and exit position. Manual override is possible when errors are detected. Rubber-coated commodity rollers mountable to cantilevered axles engage and launch cards into the air when shuffled in the shuffling chute. Cards settle back into the stack of cards under the influence of gravity. The shuffler is mounted inside a simple enclosure. Maintenance and interface features provide convenience when working with the shuffler. Authentication may be employed to correlate user or dealer with operation of the shuffler.

The present invention is a suture device generally intended for use in puncture wounds of a body cavity. The suture device can be inserted through the tissue layer into the body cavity and extend needles attached to a common suture line, under endoscopic vision, for engagement with the internal side of the tissue layer. The needles are deployed using a straight spring that deforms outwardly from the shaft of the suture device when a force is applied to the spring. Because of the inherent characteristics of the spring, it bends perpendicular to the shaft of the suture device and the removably attached needle is moved outwardly while staying generally parallel to the shaft of the suture device. Once the force is removed on the spring, the spring returns to its original position close to the body of the shaft.
