  • Publication number: 20240260910
    Abstract: Hydrocephalus and shunt-related expenditures cost the US system over $2 billion dollars in annual expenses, with 125,000 shunt surgeries per year and an untreated mortality rate estimated at 50-60%. Existing diagnostics are expensive, inaccurate, and often harmful or invasive, and can lead to unnecessary admissions, further testing, or needless surgery. Collaborative efforts between Northwestern materials engineers headed by Dr. John Rogers alongside the leadership of neurological surgeons at Northwestern Memorial Hospital and Lurie Children's Hospital have produced and validated a noninvasive, thermal biosensor capable of diagnosing ventricular shunt malfunction.
