Info

Shunt failure diagnostics • Common components: • Sensors (pressure or flow) • Some source of power (wireless or battery) • Option #1. External reader & transmitted power: on‐demand measurement (clinic, home) • Option #2. Implant with battery: potential for continuous monitoring to identify problems before they occur (and generate useful data)
Reader‐based flow diagnostics • NeuroDx ShuntCheck with Micropumper • Flow sensor based on classic “ice cube” test • Over‐skin sensor (no implanted parts) • multiple NIH SBIRs, some clinical testing
