Patent ID: 8092477

Claim:
A device for making a cut in a tissue, comprising: a trocar constructed and arranged so that a distal end of the trocar can be placed on the tissue and inside said trocar a reduced pressure can be generated for holding the tissue pressed against the distal end under the influence of said reduced pressure, a cutting member located in the trocar, such that the tissue pressed against the distal end and the cutting member can be moved relative to one another to make the cut, and a planar tissue support extending transversely over an internal passage of the trocar close to the distal end thereof, with which said tissue support the tissue that extends over the lumen of the trocar can make contact under the influence of the reduced pressure inside the trocar, wherein said tissue support comprises one of a grating and a mesh, said grating or mesh having a passageway for the cutting member, and the cutting member is moveable to and fro in a direction parallel to the plane of the tissue support.
