Extracorporeal Blood Pump
The TandemHeart® System is a continuous-flow centrifugal assist device that provides temporary circulatory support for acute heart failure patients.
When CardiacAssist needed a partner to help them develop the TandemHeart System, they turned to Minnetronix for our specific expertise in fluid integration and pump control design with safety-critical devices. Our team developed a dual controller system with integrated control loop and monitor that ensured effective and consistent therapy and patient safety. The robust device met both performance requirements and CardiacAssist’s aggressive commercialization schedule.
How Minnetronix Added Value
- Safety-critical design – Integrated non-invasive Doppler flowmeter for volume measurement and saline line bubble detector to ensure patient safety
- Balanced competing design constraints – Managed critical drive circuitry at appropriate operating temperature within sealed enclosure
- Robust design – Delivered a rugged controller with an integrated single board computer and custom-designed operating software to communicate with unique TandemHeart pump architecture
- Multipurpose architecture – Designed for pole-mounted, bed-mounted, and tabletop use, complete with pump control and a power management algorithm
