New design principle could prevent catheter failure in brain shunts – MIT News

This is a time-lapse microscopic image of particle-based flow visualization inside a ventricular catheter. The image shows the confluence of three flows: the upstream flow coming from the catheter tip direction and two flows coming in via holes facing each other.

For medical professionals treating hydrocephalus — a chronic neurological condition caused by an abnormal accumulation of cerebrospinal fluid (CSF), resulting in pressure on the brain — there have been a limited range of treatment options.
