OBJECTIVE: The tips of clip blades are often invisible during operations on large, deep, or posteriorly projecting aneurysms. To overcome this problem, we sought to develop a series of scaled clips. METHODS: We made scaled clips modified from Yasargil titanium clips. The blades of the new clips are scaled every 5 mm from the tips with alternating colors. We have added six new types of straight scaled clips. RESULTS: To date, we have performed approximately 40 aneurysm clippings using the new scaled clips and have confirmed their usefulness. CONCLUSION: Scaling on the blades helps confirm accurate placement of a clip, even during operations for large, deep, or posteriorly projecting aneurysms, in which blade tips are often invisible.
