Pre-shaped technique using LEONIS Mova: Steering catheter for challenging cerebral aneurysm treatment with WEB

Abstract

This case report highlights the use of the LEONIS Mova, a steerable microcatheter, to facilitate Woven Endo-Bridge device (WEB) deployment in a cerebral aneurysm case. An 85-year-old man with a left posterior communicating artery aneurysm underwent successful WEB placement using the LEONIS Mova, which was prebent outside the body and fine-tuned inside. This approach allowed for precise navigation and stable deployment. The LEONIS Mova's dual-direction 180° steering capability proved advantageous over single-direction devices, such as the Bendit. While promising, the report acknowledges limitations due to its single-case nature and the unpredictability of catheter behavior in complex anatomy. Further studies are needed.
