Anti-seeding arrangement

An arrangement adapted to avoid seeding infectious cells during invasive medical procedures on a human body or an animal body, the arrangement comprising:

• an electromagnetic field generator;
• an elongated hollow member having two ends and an electrode, the electrode positioned such that one portion of the electrode is at one of the two ends of the elongated hollow member, the electrode being connected to the electromagnetic field generator, the elongated hollow member being configured to be inserted into a human body or an animal body;
• a sensing unit configured to sense a penetration depth of the elongated hollow member in tissue;
• and
• a control unit arranged to control the electromagnetic field generator so as to deliver radio frequency (“RF”) energy bursts to the electrode and being arranged to receive the sensed penetration depth from the sensing unit and control the electromagnetic field generator in dependence on the sensed penetration depth and comprising a triggering unit arranged to trigger the electromagnetic field generator to deliver RF energy bursts in dependence on variations of the sensed penetration depth of the elongated hollow member.

• a sensing unit configured to sense an effective penetration depth of the elongated hollow member in tissue, the effective penetration depth being varied in dependence on the movement of the hollow insulating sheath along the elongated hollow member;
• and
• a control unit arranged to receive the sensed effective penetration depth from the sensing unit and control the electromagnetic field generator to deliver radio frequency (“RF”) energy bursts to the electrode, and being arranged to control the electromagnetic field generator in dependence on the sensed penetration depth, and comprising a triggering unit arranged to trigger the electromagnetic field generator to deliver RF energy bursts in dependence on variations of the sensed effective penetration depth of the elongated hollow member.
