Abstract: In order to permanently position a tubular implant in a vessel in such a way that it is sealed off in relation to the vessel wall, a device for inserting such an implant is proposed, which is characterized by an introducing head having an advancing handle and being insertable into the implant, with radially outwardly movable spreading elements arranged on the circumference of the introducing head, and by a locking member mounted for displacement on the introducing head and displaceable via a transmission member between a rest position in which the spreading elements are radially retracted and a spread position in which the spreading elements protrude radially outwards.

Abstract: The invention relates to a sterilizing system for sterilizing containers. In accordance with the invention, an external actuating element is provided in an autoclave chamber structure to hold special closure elements and/or the container lid in an open position and to bring them into a closed position before the autoclave is opened.

Abstract: The clip consists of two separate branches, the facing surfaces of which have profiles which allow the pressure effecting occlusion of the oviduct or vas deferens to be generated only in two separate pressure zones while a cavity is formed as nutrition zone between the two pressure zones to relieve the oviduct or vas deferens of pressure and enable its tissue to be nourished. The branches are connected with one another at both ends by detent closure means.
