Microcatheter Shape Adjustment during Coil Embolization with the Leonis Mova Steerable Microcatheter.
Article in Journal of neuroendovascular therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: The Leonis Mova (SB-Kawasumi Laboratories, Kanagawa, Japan) is a steerable microcatheter with a hand-operated dial that can be used to adjust the angle of the catheter tip. This steerable microcatheter has predominantly been used as an intermediate catheter. Herein, we report a case in which an aneurysmal subarachnoid hemorrhage was treated with coil embolization using the Leonis Mova microcatheter. Case Presentation: A 53-year-old woman was transferred to our hospital for the treatment of a sudden onset of headache and vomiting caused by a subarachnoid hemorrhage detected on CT. DSA showed a 7.5-mm left internal carotid artery-posterior communicating artery aneurysm with multiple blebs, which we treated with coil embolization under general anesthesia. After placement of a 7-Fr guiding sheath in the left internal carotid artery, we introduced the Leonis Mova Selective microcatheter and the Excelsior SL-10 microcatheter (Stryker, Kalamazoo, MI, USA) into the center of the aneurysm. We inserted 9 coils into the aneurysm via the double-catheter technique, during which we adjusted the angle of the Leonis Mova microcatheter to fill each bleb in a piecemeal fashion. Almost complete obliteration was achieved, and the patient was ambulatory and discharged after completing treatment for the vasospasm phase of a subarachnoid hemorrhage. Conclusion: The Leonis Mova may be a useful microcatheter for coil embolization of aneurysms with multiple blebs and a tortuous parent artery.
