Anti-seeding arrangement

An arrangement adapted for biopsy, the arrangement comprising:

• an elongated hollow member to receive a biopsy sample,
• the elongated hollow member having:
• two ends and
• an electrode,
• the electrode including a plurality of segments,
• at least one portion of the electrode being arranged at least near one of the two ends of the elongated hollow member,
• the electrode being connectable to an electromagnetic field generator, and
• the elongated hollow member being arranged to be at least partly inserted into a human body or an animal body to receive the biopsy sample,
• sensing means arranged to:
• sense a movement of the elongated hollow member, and control means,
• the control means:
• arranged to control the electromagnetic field generator for delivering radio frequency bursts to the electrode of the elongated hollow member,
• being connectable to the electromagnetic field generator, and including trigger means to:
• trigger the electromagnetic field generator to deliver the radio frequency bursts when the sensing means senses the movement of the elongated hollow member, and
• the control means being to:
• turn off a particular segment, of the plurality of segments of the electrode, at an air-skin interface of the elongated hollow member based on an impedance between at least part of the electrode and a counter electrode.
