[0119] FIGS. 11A-11D shows a sequence of functions performed by the robotic apparatus 900 to place a box 1100 on the conveyor 904 . In FIG. 11A, the control system 926 causes the conveyor belt 910 to contact a box 1100 in a stack of boxes. Then, in FIG. 11B, the control system 916 causes the air pump 916 to create a negative pressure in the roller 906 , which may engage the box 1100 by suction. In FIG. 11C, the robotic apparatus 900 pulls the box 1100 to expose an edge of the box 1100 from the stack of boxes. Then, in FIG. 11D, the conveyor 904 is then moved under the exposed edge of the box 1100 and the conveyor belt 910 is rotated to place the box 1100 on the conveyor 904 .

[0095] If an article is determined to be “acceptable”, the controller 80 signals the solenoid valve 87 to permit vacuum air to be applied to the selected variable vacuum portion 74 associated with the selected nozzle 77 , which allows the selected nozzle to remove (e.g., by suction) the individual article from that pocket in the carrier bar. As the drum 75 continues to rotate relative to the vacuum shoe 72 , the nozzle will move from communication with the associated variable vacuum portion 74 to the constant vacuum portion 73 which will continue to retain the article with the nozzle. Further rotation of the drum will move the nozzle out of communication with the constant vacuum portion and allow the article to eject or fall into the accepted product discharge chute 90 .

[0147] A tissue stabilizer employed for this purpose may have one or more stabilizer feet, preferably at least a pair of feet to be positioned on opposite sides of the coronary artery to be operated upon. The contact surfaces of the stabilizer may be adjustable as to the orientation with respect to the remainder of the stabilizer to adjust to a proper contact of the tissue surface. Various types of stabilizer feet may be employed, including those with one or more mechanical stabilization surfaces, as well as those having one or more contact members that grasp the surface of the heart by suction.
