Ever since our founding, we have applied over three hundreds of patents, covering the field of extracorporeal ventricular assist device, percutaneous ventricular assist device, ECMO systems, organ care system…etc.

Over 60% of applications are invention patents, including international patents under PCT (Patent Cooperation Treaty).

In the past, it was rare to improve flow path for blood pumps as most product design focused on overall performance, which provided limitations for enhancing hemocompatibility. 

With the latest computational fluid dynamics technology, magAssist successfully improves fluid performance, eliminating the dead zone of flow field and lowering the shear force, which brings high enhancement in hemocompatibility, reduced blood damage. The optimised blade design has improved hydraulic performance and ensured even flow distribution. 

Full magnetically levitated technology provides a controlled, large blood flow gap, which reduces the damage caused by the impeller rotor to blood cells during motion and further improving hemocompatibility.

The previous generation of blood pumps used sliding bearings (including single pivot bearings) submerged in blood to provide support to the rotor through mechanical contact, which generated large shear forces, local flow dead zones and non-physiological high temperatures in the mechanical part of the bearing in contact with the blood. 

 Although design can be improved by fluid flushing, the design of self-flushing (blood flushing) is very complex and difficult to meet the needs of many working conditions; moreover, the use of external fluid flushing can cause many side effects (e.g., hemodilution).

Mechanical bearing blood pumps have shown serious hemocompatibility problems in clinical use. The advent of suspension technology provides a controlled, larger blood flow gap, reducing the damage to blood cells caused by the impeller rotor in motion and further improving hemocompatibility. 

magAssist's design based on mechatronics significantly expands the clinical application scenarios, allowing ventricular assist device to be applied in ER or an ambulance compared to traditional ones limited to use in ICU. 

Our mechatronics technology enhances energy conversion efficiency, improves vibration resistance and reduces device size. The drive motor and active magnetic bearing are the core components of the pump, which include requirements of its size, performance, and low heat generation. magAssist has developed our own technology while the motors and bearings available in the market do not meet the design requirements of our product. The design of the flow path is also taken into consideration in our design.
