Abstract: The invention concerns a device for the fixation and manipulation of those tissues which are at least temporarily suitable for being fixed by suction. Hereby, tissues are understood to be, in addition to organic tissues, such as e.g. tissues of animals and humans, also inorganic tissues, such as films or textiles. In particular, the invention concerns a device for the fixation and manipulation of tissues which surround sensitive organs, such as e.g. the pericardium in humans. Furthermore, the invention concerns a method for the fixation and manipulation and, in particular, for puncturing of such tissues or the underlying areas.

Abstract: The invention relates to an arrangement which can be fixed to the inside of a cavity by means of fixing means which are associated with said arrangement. Said fixing means fix the arrangement in relation to at least one part of the wall of the cavity which is to be examined, wherein the arrangement must at least partially be inserted. Said arrangement enables the instruments, which are used to examine/manipulate cavities, even when the arrangement and/or the instrument is displaced in a translatory and/or rotational manner, in particular, in angled cavities, to be guided in a reliable manner.
