Abstract:
1. A biopsy material holding device for a biopsy cannula insertable into a proximal end of the biopsy cannula and between an inner wall of the biopsy cannula and a tissue-removing cylinder to perform transcutaneous biopsies of tissues, said biopsy material holding device comprising a wire having a proximal end, a distal end and a wire tip at said distal end with bevelling arranged at the wire tip, said wire being bent in a bending direction at a pre-stress angle arranged at the proximal end of the wire, wherein the wire has a uniform round cross section between said pre-stress angle and said bevelling, said bevelling facing away from the bending direction, so that the wire including the wire tip glides along the inner wall of the biopsy cannula when inserted into the biopsy cannula.
