EmboRatio vs EmboVol

Displays the required length of the coil for the volume of the aneurysm. The current embolic rate can also be calculated. The Coils available only in Japan is listed.

EmboVol is a lightweight calculator for estimating coil packing density—also called the Volume Embolization Ratio (VER)—during intracranial aneurysm coiling. Use it in three simple steps: Aneurysm: Enter aneurysm size (3 dimensions) or volume. Plan: Choose a coil system and target packing %, then get an estimated total coil length/volume from a simplified model. Procedure: Log each opened coil package and mark whether its coil was deployed. Running opened/deployed totals and grouped counts stay visible while EmboVol estimates achieved packing density, deployed coil volume, and residual volume. Key features • Aneurysm volume from 3 dimensions (ellipsoid approximation) or direct volume input • Coil volume from outer diameter (OD) and deployed length (cylindrical approximation) • Target packing slider with instant required-volume/length estimates • One-tap package logging with quick Repeat and Undo • Separate opened-package and deployed-coil counts • Editable coil catalog with visible source and provenance information • Save, restore, and QR transfer without patient identifiers • On-device only: no accounts, no tracking, no patient data collection Important EmboVol provides simplified estimates and is not validated clinical decision support. Always cross-check calculations, units, and device specifications against current IFU/product documentation and local protocols.
