Abstract: In a prediction game method, system en server, data are transmitted and received through a network between a server and a user terminal. Computer software is provided to store a plurality of event data items and corresponding status data items, indicating whether the corresponding event has taken place or not, each data item associated with an event. A plurality of event data items for future events are transmitted to a user identified by a user identification. At least one choice data item transmitted by the user is received, each choice data item relating to a corresponding event data item, and indicating whether the user predicts the future event indicated by the corresponding event data item to take place or not. Received choice data item are stored in association with the corresponding event data item and the user identification. When an event becomes a past event, the corresponding status data item is updated.

Abstract: The invention relates to an assembly comprising on the one hand a graft vessel and on the other hand an anastomosis has connector. The connector comprises a ring and two pins. Each pin has a free end and a fixed end connected to the ring. The pins extend, viewed from the fixed end towards the free end, next to and set apart from each other. Each pin has an overlap section where the pin, viewed in axial direction of the ring, overlaps the plane bounded by the outer contour of the ring. The axial axis of the ring extends transverse to the wall of the graft vessel. The connector is attached to the graft vessel and the ring lies, with its full circumference, against the wall of the graft vessel. The invention further relates to a method of providing such an assembly and a method of attaching such an assembly to a recipient vessel.
