30、Magnetic fields of considerable strength e.g. to (tesla) or more are used in medicine with increasingfrequency as part of diagnostic techniques such as magnetic resonance imaging (MRI). Exposure to electromagneticradiation may pose a hazard to patients who have intracranial aneurysm clips. Clips wit

31、h magnetic properties (dia-,para-, antiferro-, ferro- and/or ferrimagnetic) become magnetized when subjected to a magnetic field and under thiscondition are liable to directing forces. These forces may result in the clip being removed from the aneurysm that itwas intended to occlude and even being m

32、oved through the tissues. Because of the very high field strengths, evenmaterials normally regarded as non-magnetic may exhibit some response to the magnetic field, such as minimaldeflection or rotation. It is therefore essential that aneurysm clips have weakly or non-magnetic properties.Compounds o

33、f certain non-magnetic elements may, when processed, have strong magnetic properties. The oppositealso occurs. The work done at manufacture may have an additional effect. However, material normally regarded asnon-magnetic may exhibit some response when subjected to MRI levels of field strength.A sec

34、ondary effect is that the presence of a metallic clip may interfere with the MRI process, resulting in deteriorationof the quality of the scanning image.One of the main intentions of this International Standard is to help to ensure that appropriate and comparableinformation is supplied for each clip

35、 in order to facilitate the choice of the correct clip by the surgeon. The closingforce of the clip is an important factor in the selection process, and this International Standard requires that themanufacturers determine the closing force in a uniform manner and state this value on the labelling. T

36、he actuation ofsome types of clip can unduly result in a reduction of the closing force.0,2 T 2,0 TBS EN ISO 9713:2009BS EN ISO 9713:2009INTERNATIONAL STANDARD ISO 9713:2002(E) ISO 2002 All rights reserved 1Neurosurgical implants Self-closing intracranial aneurysm clips1 ScopeThis International Stan
