For practitioners
How Regenis delivers what conventional injectors block
Regenerative biostimulators are suspensions of solid microspheres. Conventional injector needles are specified for solutions. This page sets out the delivery problem that follows, and the engineering Regenis uses to address it.
The failure mode
Microspheres pack and bridge at the needle hub
Where the hub narrows into the cannula, suspended microspheres can pack and bridge across the opening

Needle tips also change shape with reuse — a separate problem from hub packing, documented on the same manufacturer plates.

Why it happens
Manual reconstitution does not distribute evenly
Biostimulator microspheres are solid and denser than their carrier, so they settle. How thoroughly a syringe is mixed by hand determines how evenly the dose is distributed — and that varies between operators and between passes.

Sensing and control
Five signals, sampled continuously, resolved in a closed loop
Sensors integrated into the handpiece report at millisecond intervals. The control model reads all five together and adjusts drive output while the injection is in progress, rather than after it.
Perception
- Negative pressure
- Thrust force
- Speed
- Current
- Torque
Control model — on-device
Quad-core ARM CPU with a dedicated AI processing unit. Injection planning, clogging warning and risk analysis run on a real-time operating system.
Actuation
- Power
- Rotation direction
- Speed
Sensors report at millisecond intervals; drive output is adjusted while the injection is in progress.

Precision and interlocks
The system reports when delivery is not nominal
Nine needles share one regulated feed, so coverage is uniform across the treated area. When the drive train meets resistance outside its expected envelope, the system raises a named alarm rather than continuing silently.
