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

Anti-seeding arrangement

Fine needle arrangement for taking a sample of cells from suspicious lesions by using fine needle aspiration (FNA) technique, including a tubular needle member (), a storage compartment () enclosing a chamber, and a coupling () 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.

Fine needle arrangement for cell sampling

An arrangement for taking a sample of cells from a suspicious lesion or a tumor with the so called fine needle aspiration technique, provides a good penetration of tumors, especially small and/or hard fibrous tumors, and in the meantime yielding an increased amount of cells in the sample, by applying a longitudinal movement to the needle when the needle is penetrating the tumor and by applying both a rotational and a longitudinal movement to the needle when the needle is positioned inside the tumor. The arrangement is further provided with heat generating elements in order to apply a short pulse of heat to the needle in order to lower the risk for the tumor to spread.
