Description

Our project focuses on solving the need to decrease the amount of muscle obstruction during minimally invasive lumbar surgeries in order to increase the surgeon’s visualization of the surgical field. We developed a medical device that decreases the muscle obstruction by expanding an inflatable at the base of a cylindrical port. The product was tested in a PVA mixture that resembles similar material characteristics as muscle which proved the plausibility and efficacy of the concept.
