Newly Designed Bayonet Clips for Complicated Aneurysms

Abstract

Three newly designed bayonet clips (crankshaft clips) are presented. They were designed to occlude aneurysms with irregular necks by using the angle and shank portion of a bayonet clip (shank clipping). The new clips have shorter distal blades and longer shanks (proximal blades), and the angle portions are bent to an angle of smaller degree. These clips are useful particularly for aneurysms located in a wider space.
