Cranial Model Creation

The model for direct aspiration thrombectomies must:

• accurately model and measure intracranial pressure (ICP)
• accurately model blood vessel shape and size in which the vacuum catheter will be inserted
• contain materials that accurately model the mechanical properties of the components of the cranial compartment (brain tissue, CSF, blood)
• accurately model the biomechanics of vessel movement caused by vacuum catheter operation
• respond to an increase in ICP in a manner that accurately replicates physiology and anatomy
• accurately model blood flow through vessels in the brain during normal conditions as well as during elevated ICP conditions.
• be simple enough for physicians to perform practice thrombectomies on
• create a minimal mess when undergoing a practice thrombectomy
• be safe to use in all settings, regardless of environmental burdens
• be made of cheap, obtainable, and abundant materials
• be compatible with existing catheters and not cause them any damage

Model Testing

The testing of the model should:

• determine if increased ICP affects pressure gradients across the blood clot
• reveal insights into developing a more efficient means of direct aspiration thrombectomy
