Stop guessing catheter compatibility. CatheterStack shows what fits, what’s tight, and when injection becomes unrealistic.

CatheterStack helps neurointerventional teams plan catheter configurations before and during procedures. Build a “stack” (parent catheter + devices inside) and instantly see whether the combination is feasible and how tight the remaining lumen becomes.

Key features • Compatibility & fit planning • Add common neurointerventional devices and evaluate whether they can coexist in the selected parent catheter. • Visual cross-section view with clearance/halo indicators to highlight tight configurations. • Remaining lumen metrics • Effective remaining diameter and area after device stacking. • Quick identification of “tight” setups that may limit navigation or injection quality. • Injectability estimates • Hand-injectable flow estimates and required force/pressure (based on simplified fluid-resistance modeling). • Clear warnings when a configuration is unlikely to be injectable by hand. • Practical warnings • Traffic-light guidance for clearance (easy / tight / high risk).

Intended use / disclaimer

CatheterStack is a planning and educational tool. It provides estimates based on published device dimensions and simplified physical models. Real-world performance depends on anatomy, tortuosity, friction, technique, temperature/viscosity of contrast, and device variability. Always follow manufacturer IFUs and clinical judgment.
