HeartCon II highlights: ~75g pump, 21.5mm thick, sensorless self-controlled levitation, no in-pump sensors/circuit board, 1,400–3,600 rpm, up to ~10 L/min flow. Illustrative.
In short: Beijing Anzhen Hospital's cardiac team completed Beijing's first HeartCon II ('Rocket Heart 2.0') LVAD implant. This domestic new-generation maglev artificial heart weighs just 75g and is 21.5mm thick, with sensorless self-controlled levitation and no in-pump circuit board, sensors or electronics for higher intrinsic safety; at 1,400–3,600 rpm it delivers up to 10 L/min assist flow, with hemocompatibility better than peers, serving adults, adolescents and even children, with potential for right-heart use.

Smaller, lighter, safer

At ~75g and 21.5mm thick, it is an exceptionally small maglev pump that needs no in-pump sensors; with no circuit board, sensors or electronics inside, intrinsic safety is higher and it suits very-low-weight patients and minimally invasive implantation.

Performance and hemocompatibility

At 1,400–3,600 rpm it delivers up to 10 L/min; the smaller pump doesn't trade off higher speed, so blood damage is low and hemocompatibility beats peers, with low temperature rise and high reliability.

Wider use and self-controlled IP

Beyond full-flow left-heart support for adults, it can assist adolescents and children, with potential for right-heart failure; it stays med-engineering integrated with fully self-owned IP and all components made domestically for controllable cost.

The BIO angle

The smaller the pump, the more extreme the materials engineering needed in sealing, bearings/levitation and the blood interface; low temperature rise and low blood damage come from material-structure synergy. Advanced medical silicone and functional materials in pump sealing and interfaces are BIO's focus.

FAQ

How small is 'Rocket Heart 2.0'?

~75g and 21.5mm thick — an exceptionally small fully maglev blood pump that needs no in-pump sensors.

Why is a sensorless pump safer?

Sensorless self-controlled levitation with no in-pump circuit board, sensors or electronics removes potential failure points, raising intrinsic safety and reliability.

Can it be used in children or the right heart?

It can assist the left heart in adults, adolescents and children, with potential to assist the right heart in right-heart failure.
