Positioning marker

Abstract

The present invention relates to an implantation assembly comprising a hollow needle (20) with a longitudinal axis (L) and an opening slanted at an first acute angle in relation to a plane perpendicular to said longitudinal axis (L), a mandrel (21) adapted to slide within the inside the needle along the longitudinal axis (L), and a plurality of positioning markers (10), wherein each of the plurality of markers (10) comprises an elongated marker body (11) with a proximal end (12) and a distal end (13), wherein said proximal end (12) and said distal end (13) of said marker body (11) is slanted essentially at a same second acute angle (α) in relation to the plane, wherein said plurality of positioning markers (10) are mounted distally of said mandrel (21) within said needle (20) and proximally of the distal end of said needle (20) before implantation, and said plurality of positioning markers (10) being adapted to be implanted using said hollow needle (20) and said mandrel (21), wherein the marker body (11) of each of the said plurality of positioning markers (10) is adapted to tilt and rotate in reference to the longitudinal axis (L) of the needle after exiting the slanted opening of the needle (20).
