SECTION 2
Magstim Alpha Coil Range
Operating Manual
WARNINGS AND PRECAUTIONS
Caution
Consult accompanying documentation before using the coil.
Type BF Applied Part: Refer to Section 6.1 for further information.
High Voltages: High voltages are present in the Alpha coils during operation. Refer servicing to
qualified personnel. If there is any sign of external damage or if any parts are damp or wet, they
must not be used.
Magnetic Pulses: The coils generate high intensity magnetic pulses, which induce eddy currents
in any conductive medium, such as the human body, nearby metallic objects or electronic devices.
Therefore, the coils:
•
must not be used on, or in the vicinity of subjects with cardiac demand pacemakers,
implanted defibrillators, or other electronic or metallic implants;
•
must not be used in a position where the current can be induced in cables or wires
that are directly connected to the subject;
•
must not be used in the vicinity of objects that are sensitive to magnetic fields, such as
watches, credit cards and electronic equipment;
•
must not be used when in contact with metallic objects, as these objects may be
propelled or damaged by the magnetic field of the coil; and
•
must not be used if the Alpha coils have any external damage, or if any part is damp
or wet.
Explosive and Flammable Atmospheres: The Magstim Alpha coils must not be used in an
explosive atmosphere, around explosive gases or in the presence of flammable anaesthetics.
Modification: No modification of this equipment is allowed.
Surface Temperatures: The coil surface temperature will continue to rise following activation of
the stimulator's coil over temperature function; therefore, the coil must be removed from the
subject as soon as the system indicates that the coil has reached maximum temperature.
Discharge noise: When the magnetic pulse is delivered, a discharge click is produced that may
startle. The use of ear protection by the patient and operator is recommended. If any protocol is
being delivered at a power level above 70%, the use of ear protection by the patient is required.
Seizures: Cortical magnetic stimulation runs the risk of inducing seizures. Magstim concurs with
the advice given in the paper titled "Safety, ethical considerations and application guidelines for
the use of TMS in clinical practice and research" by Rossi et al (2009) in respect to screening
candidates prior to administering TMS.
