Abstract: The invention is directed to a steerable mandrel comprising a stationary part and a movable part. The stationary part comprises a tubular sleeve having a mantle wall with a longitudinal semi-circumferential opening or weakening, which divides the stationary part into a proximal portion located on a proximal side of the longitudinal semi-circumferential opening or weakening and a distal portion located on distal side of the longitudinal semi-circumferential opening or weakening. The movable part comprises a rod-like member, which is slidable within the proximal portion of the stationary part. The movable part is attached to distal portion of the stationary part, such that relative movement of the movable part in relation to the stationary part causes a bending of the mandrel.

Abstract: The present invention relates to a biopsy device (1) for obtaining a tissue sample. The biopsy device comprises an elongated tube shaped drill (2), extending along a longitudinal axis A, and comprising a cutting edge arrangement (3) at a distal end (4) of said drill (2). The drill (2) further comprises at least one flute (5) extending helically, along said longitudinal axis A, at an outer surface (6) of said drill (2), wherein said flute (5) extends from said distal end (4) and along a substantial part (7) of said outer surface (6) of said drill (2). The drill (2) is provided with an opening (10) at its distal end (4), wherein said opening (10) being in communication with a cavity (16) adapted to receive said tissue sample.

Abstract: The present invention relates to a biopsy assembly (1), for obtaining a tissue sample. The assembly (1) comprises an elongated tube shaped sleeve (2), extending along a longitudinal axis A. The sleeve (2) comprises a first cutting edge arrangement (3) at a distal end (4) of said sleeve (2), said sleeve (2) being provided with an opening (5) at said distal end (4), wherein said opening (5) being in communication with a cavity (6) adapted to receive said tissue sample. The assembly (1) further comprises an elongated drill unit (7), adapted to be removably arranged in said sleeve (2), and extending along a longitudinal axis B, said elongated drill unit (7) comprising a second cutting arrangement (8) arranged at a distal tip (9) of said drill unit (7).
