Abstract: A ligator system for applying an expanded ligator ring to an anatomical region of a living being to be ligatured by the ring in its relaxed state, which comprises a ligator with a holding tube, which receives inside it the anatomical region to be ligatured in each case and with its outer surface keeps a number of ligator rings arranged one behind the other expanded, wherein the ligator system comprises at least one intermediate ring, which is arranged on the holding tube between two ligator rings and keeps the two ligator rings at a distance from one another in the direction of the longitudinal axis of the holding tube.

Abstract: An artifact repository can be queried for a set of different pre-existing presentation artifacts based on requirements and constraints of a presentation event to produce a query result. The query result can comprise a set of presentation artifacts suitable for satisfying at least a portion of the requirements and constraints. The querying can match the artifact specific metadata against the requirements and constraints to produce the query result. An agenda comprising a set of different agenda items can be automatically constructed utilizing the query result. Each of the different agenda items can occupy a time slot of the presentation event. Creation of agenda items can be a non-manual effort automatically determined by a computing device in a data driven manner given the requirements, the constraints, and the pre-existing presentation artifacts of the artifact repository. Resources for the different agenda items can be automatically booked.
