Minnetronix offers market-leading expertise in developing customized power and control technology for ventricular assist devices (VADs), from today’s percutaneous systems to future fully implantable solutions.
The growing patient population with advanced heart failure - and the limited number of donor organs - has stimulated the use of ventricular assist devices, or VADs. However, postoperative management of VADs and their support systems can be challenging and costly.
Since 1996, Minnetronix has been working on improving the quality of life for VAD patients through next-generation VAD development. Founded by former 3M engineers, the company's initial project was the development of a software and electronics controller for an electric-motor-driven artificial heart (ETAH). This federally funded program was a joint effort between 3M Cardiovascular Systems Division, Penn State University, and Minnetronix, and it helped lay the groundwork for our technology direction and rapid business growth.
From these early days, Minnetronix has continued its work in power and control for mechanical circulatory support systems.
To improve quality of life for patients, our next-generation VAD development efforts strive to:
- Eliminate the percutaneous driveline and its related complications,
- Reduce the size and weight of the controller and its accessories,
- Minimize the number and the inconvenience of cables,
- Increase battery life, and
- Improve usability and patient comfort.
Since our first work in VADs, we have successfully tackled many technical challenges including motor control efficiency, power management, energy transmission, control feedback, and live battery exchange. We have created a robust intellectual property (IP) portfolio that covers areas including:
- Integrated external controller
- Easy-to-use replaceable battery
- Integrated back-up battery
- Efficient field-oriented motor control
- Graphical user interface
- Transcutaneous energy transmission method
- Communications via a wireless power channel
Our broad IP can be applied across a range of applications for VAD power and control solutions.
Based on this IP, Minnetronix developed innovative, proprietary technologies that support ventricular assist devices, from today’s percutaneous driveline systems to future fully-implantable systems. These technologies include our Magic™ platform for VAD power and control and our exclusive transcutaneous energy transfer system (TETS).
Minnetronix’ Magic technology offers an advanced, easy-to-use platform for VAD power and control. The Magic technology is available in two models: the Magic PE controller for percutaneous driveline systems, and the Magic TE power controller for fully-implantable VAD systems.
In addition to the Magic technology platform, Minnetronix also developed a patented TET system to wirelessly power fully-implantable VAD systems. The Minnetronix TET system has been optimized for performance and safety and offers many key advantages over competitive systems. Unlike other systems, the Minnetronix system requires only a single channel for power transfer. No secondary RF channel is required, eliminating the risks of RF communication failure.
The Minnetronix system is the only TET system with clinical performance supporting a VAD, backed by 25 patient-years of clinical data with zero TETS-related adverse events. Based on these results, the system has an established reputation for clinical safety.
To date, Minnetronix has completed 24 VAD-related programs for 14 customers, including the design, development and current commercial-scale production of a PMA-approved VAD system. We have worked with numerous established companies, start-ups, and researchers on technologies including:
- LVADs/ RVADs /Bi-VADs
- Rotary Pump Platforms
- Heart Lung Machines
- Sensor and Sensorless Motor Control
- Physiologic Response Systems
- Flow and Negative Pressure Estimation
- Wireless Telemetry
- Transcutaneous Energy Transfer
Minnetronix has more VAD power and control experience than any other industry partner. No matter where you are in your pump development process, Minnetronix has the technology and expertise to help get you to market as quickly as possible.
