Abstract: The present invention relates to an arrangement for taking a biopsy in a human or animal tissue, comprising an elongated hollow member having a circular cross-section in a plane perpendicular to a longitudinal axis, and a circular cutting edge at distal end. The circular cutting edge is provided with at least one cutting slit, running from the cutting edge in a proximal direction of the elongated hollow member. The arrangement further comprises a rotational member configured to apply rotational movement to the hollow member, wherein the rotational movement is applied in accordance to a rotational procedure such that the hollow member is rotated in one direction a predefined amount of rotations, and thereafter rotated in an opposite direction the same amount of rotations.

Abstract: The present invention relates to an anti-seeding arrangement (100) for invasive treatment of a human or animal body comprising an elongated hollow member (102), and a first electrode (116) of which one portion is arranged near one end of the elongated hollow member (102), said first electrode (116) being connectable to an electromagnetic field generator (110), wherein the elongated hollow member (102) is arranged to be inserted into the human or animal body, control means (106, 108) arranged to control the electromagnetic field generator (110) for delivering radio frequency bursts to the first electrode (116), and sensing means (104) to sense a physical property dependent on the insertion length of the elongated hollow member (102) in the human or animal body, and wherein the control means (106, 108) is arranged to control the operation of the electromagnetic field generator (110) in dependence of the sensed physical property.

Abstract: Fine needle arrangement for taking a sample of cells from suspicious lesions by using fine needle aspiration (FNA) technique, including a tubular needle member (1), a storage compartment (2) enclosing a chamber, and a coupling (3) to which a connector may be attached. The chamber is configured with a gradually increasing cross-sectional area from the distal part of the chamber to the proximal part of the chamber, such that the chamber has no residual spaces where cell samples may be trapped, and that an efficient air streaming is achieved.
