  16  Probes and Biopsy
• The magnetizer should be used with the needle cap. Disinfect the 
magnetizer after use.
• The needle cap is a sterile, single use device. To maintain procedural 
sterility, it is important that the needle cap is isolated from non-sterile 
objects.
• Keep the magnetizer away from any device that is sensitive to magnetic 
fields. Never place or hold the magnetizer within 1 m of the probe.
• The eSpacial Navi system supports only the needle types listed on the 
needle list. For details, see “16.4.1 Interface”.
• Keep the L11-3VNs away from the source of disturbance, such as metal 
objects and magnetized objects. Do not use or store L11-3VNs in the 
vicinity of strong electric or magnetic fields.
• When used under optimal operating conditions by an experienced medical professional, the 
eSpacial Navi system can achieve precision as high as ±2.4 mm.
• Place the magnetizer in the proper position to prevent the magnetizer from falling off or 
becoming damaged.
• DO NOT make the magnetizer overheated (more than 50 °C) during cleaning and 
disinfections. High temperature may cause the magnetizer to become deformed or damaged.
