Patent number: 11246652Abstract: Surgical tissue fusion instrument and support structure having two gripping structures which are movable relative to each other and which are designed to bring together biological tissue sections that are to be connected to each other, with heat-generating means which are assigned to the gripping structures and, during tissue fusion, cause heat to be introduced in the area of a connection site of the biological tissue sections, and also with a support structure which is held between the gripping structures and, during tissue fusion, is operatively connected to the tissue sections. The support structure has at least one additional physical functional structure for aiding or promoting the tissue fusion.Type: GrantFiled: March 18, 2016Date of Patent: February 15, 2022Assignee: AESCULAP AGInventors: Rainer Bargon, Bernd Blender, Stefan Eick, Nikolaus Hafner, Patrick Heizmann, Eugen Herner, Christian Huber, Christof Merckle, Erich Odermatt, Christoph Rothweiler

Patent number: 10779844Abstract: Surgical tissue fusion instrument having two gripping structures which are movable relative to each other, are designed for gripping and bringing together biological tissue sections, and are assigned heat-generating means designed in such a way that tissue fusion takes place between the biological tissue sections by heat being supplied in the area of the gripping structures. At least one gripping structure is assigned a fluid-conducting system, which is designed to supply at least one liquid or flowable additive to the tissue sections during a tissue fusion process.Type: GrantFiled: March 18, 2016Date of Patent: September 22, 2020Assignee: AESCULAP AGInventors: Rainer Bargon, Bernd Blender, Stefan Eick, Nikolaus Hafner, Patrick Heizmann, Eugen Herner, Christian Huber, Christof Merckle, Erich Odermatt, Christoph Rothweiler
