Studies and Results

A First Look at RetractiSens Prototyping Results

Due to the COVID-19 pandemic, prototyping was unfortunately cut very short. However, we made great progress even with the little time we had to formulate a solution to our dire clinical problem.


Pressure Sensor Proof of Concept

Future Plans

  • In Silico Studies

    • 3D volume conductor model for electric currents and structural mechanics using Comsol Multiphysics

      • Ensure that functionality of the RetractiSens is not affected by the bending of the retractor blade and by the application of electrodes and pressure sensors to the retractor surface

    • Electrocorticography (ECoG) Simulation

      • Ensure that application of a function generator simulating ECoG signals will result in accurate and precise RetractiSens recordings

  • Animal Studies

    • Ensure proper biocompatibility of the RetractiSens with brain tissue (ISO 10993-1)

    • To validate the function of the electrodes and pressure sensors through precision and accuracy verification standard tests

  • Clinical Trials

    • Randomized control trials

      • Ensure that risk of use and retraction-induced brain damage is statistically significantly reduced when using RetractiSens compared to currently used brain retractors

      • Ensure that length of surgery when using RetractiSens is not statistically significantly increased compared to currently used brain retractors
