Abstract: An element for use in anastomosis and a method and apparatus for installing the element (having tines that extend from a central portion) at the open end of a blood vessel (or other tubular body structure). To install an embodiment of the element; a carriage holds the element and shields the tines, the vessel's open end is passed through the shielded element and fitted over an anvil, the tines are exposed, and the carriage is actuated to fire the element against the anvil so that the tines pierce the vessel and curl against the anvil (everting the tissue around the vessel's open end). The anvil preferably forms the vessel end portion into a hooded shape suitable for creating an anastomotic junction.

Abstract: An apparatus has one or more arms extending from a rotating hub, and players jump over the arms for enjoyment or exercise. Specialized sockets or other mechanisms connect the arms to the hub such that the arms can be placed in myriad different positions, and the arms can be moved out of the way when they strike a player. Rotation of the hub can be motorized, with a mechanism for automatically stopping the rotation when any of the arms is dislocated from its socket.
