Control Devices TRIZ Cases
- LVAD Controller Algorithm for Suction Management
A controller adjusts impeller speed to manage suction events in an LVAD.
- Expandable Percutaneous Heart Pump Resolving Size-Flow Contradiction
Dynamic expansion resolves the contradiction between small delivery size and high cardiac flow rate requirements for percutaneous support.
- Implantable Blood Pump Backup Control for Communication Loss
A segmented mechanical circulatory support system uses autonomous backup parameters to ensure uninterrupted pump operation during communication losses.
- Vehicle Speedometer Calibration via Acceleration Integration
A vehicle speedometer calibration method integrates longitudinal acceleration data to determine velocity.
- Implanted Medical Device Coil Power Transfer Heat Flux Control
A control system calculates coupling coefficients between external and implanted coils to manage power transfer.
- Adaptive Drive Mode System for Off-Road Vehicle Settings
An adaptive drive mode system modifies vehicle settings using sensor data to tailor performance for specific operations.
- Implantable Blood Pump Pressure Sensor Placement
Relocating the pressure sensor into the pump housing eliminates tissue overgrowth and mechanical stress while simplifying implantation.
- Peristalsis Heart Assist Pump with Inflatable Elements
Inflatable elements within a stent create peristaltic waves to pump blood bidirectionally, preventing shear damage from rotary impellers.
- Heart Support System with Intermediate Reservoir for Load Control
Segmented pump arrangement with an intermediate reservoir decouples preload and afterload, reducing heart burden while maintaining body blood supply.
- Implantable Blood Pump Integrated Controller Circuitry
Integrates power electronics and controller circuitry within the implantable blood pump housing.
- Single-Needle Blood Treatment Pump Segmentation
Segmented pump control maintains high circuit flow while delivering low patient flow for small children.
- Blood Pump Startup Control Circuit for Electrical Fault Recovery
A control circuit detects stator electrical faults and initiates a rapid startup sequence to restore blood flow.
- Bone Anchor Driveline Stabilization for VADs
A bone anchor system stabilizes ventricular assist device drivelines by transferring applied forces to the bone, preventing skin tearing and infection risks.
