## What is EmboVol?

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.

## Version history (last 3 releases)

### 1.2 — 2026-07-28

EmboVol has been redesigned around five equal workspaces: Aneurysm, Plan, Procedure, Cases, and Support. Procedure now makes it faster to log opened packages, distinguish deployed from not deployed coils, and track aggregate deployed length without recounting.

### 1.1 — 2026-07-13

Version 1.1 adds a faster, traceable procedure log:

• Track opened packages separately from deployed coils.
• See running opened/deployed totals and grouped counts.
• Keep Repeat and Undo within reach during long cases.
• Save, restore, and share cases more reliably, with clearer catalog provenance and stronger QR validation.
• Preserve calculations when updating from version 1.0.

The packing model remains unchanged.

### 1.0 — 2026-03-03

No release notes.
