Aneurysm clips: what every resident should know

Evolution of Clip Design and Mechanics Modern aneurysm clip is the result of almost a century of innovation from Cushing's malleable silver clips and Mayfield's repositionable spring loaded clips to their current modern avatar. According to McFadden, the spring mechanism was developed in 1840 by the French instrument maker Joseph Charriere. Surgeons have even fabricated clips from gold sourced from dental supply stores! [3] As the use of magnetic resonance imaging (MRI) became popular, the demand for MR compatible clips grew, leading to the use of special alloys such as MP 35 N (Sundt Slim-Line), cobalt alloys like Phynox (Yasargil FE) or Eligiloy (Sugita Standard).
