Solution Overview

Problem

Current methods for determining coiling parameters for filling lumens, such as aneurysms, with coils lack efficiency and flexibility, particularly for small aneurysms where packing percentage does not significantly impact recurrence rates, and do not allow for interactive selection of coil types and parameters during deployment.

Innovation Solution

A method and device that utilize three-dimensional rotational angiography to determine the volume of the lumen and interactively calculate coiling parameters like the number of coils, coil thickness, or coil length, allowing for selection of different coil types based on desired packing and lumen shape, with a user-friendly interface for practitioners.
