Electrocardiography TRIZ Cases
- Fiber-Optic Shape Sensing for Catheter Malposition Detection
Distributed strain sensing tracks catheter shape and detects azygos-vein entry without electromagnetic interference or fluoroscopy.
- Extracorporeal Circuit Optical Sensing for Needle Dislodgement Detection
Pressure changes trigger screening, while optical backscatter and absent heart rate verify dislodgement for faster intervention.
- Collapsible Heart Valve Catheter With Dual Annular Flow Valves
A pressure-responsive catheter uses dual annular valves to regulate antegrade flow and limit retrograde flow during valve treatment.
- Closed-Loop Neuromodulation for Biomarker-Guided Sleep Induction
Biomarker feedback adapts neuromodulation to induce sleep with less dose and time.
- LVAD Pump Speed Synchronization Using Motor Signals to Reduce Suction
This case uses filtered motor signals to time LVAD speed changes with systole and diastole, stabilizing perfusion and hemodynamics.
- Heart Pump Geometry for Sensor-Free Flow Balancing
This heart pump uses large flow paths, passive geometry, and magnetic impeller control to balance flow as pressure changes.
- Depth of Consciousness Monitor with EEG-Based Sedation Control
Continuous EEG and optional EMG analysis supports closed-loop sedation control tailored to patient responses and drug profiles.
- Bio-Potential ECG Electrodes for HRV-Based Hypoglycemia Detection
ECG electrodes capture heart-rhythm changes to validate glucose signals and guide timely insulin delivery during adverse events.
