Tiny brain implant could replace major surgery for fluid buildup

This study tests a new device called the eShunt System for people with communicating hydrocephalus, a condition where excess fluid builds up in the brain. The device is a small, permanent implant placed through a blood vessel to drain the extra fluid, avoiding the need for traditional brain surgery. The study involves 20 adults who already have a temporary drain and need a permanent solution, and it checks if the implant safely lowers pressure in the brain.
