At IMRA Surgical, we grade our hydrogel models from Class I to Class V — each level unlocking greater realism, complexity, and procedural capability.
No animal tissue. No ethical compromise.
Class I
Our entry-level hydrogel models are designed for first contact with surgical tools.
Whether you're a student learning anatomy for the first time, or an experienced surgeon picking up a robotic system for the first time — Class I gives you the space to cut, suture, and build the confidence you need before anything else.
Class II
Class II models isolate the most critical task within a procedure, so surgeons can master it without the noise of everything around it.
Need to learn how to remove a tumour? Start here. No surrounding steps, no complexity overload - just deliberate, component focused, task-specific repetition.
Class III
Once you've nailed the critical task, Class III turns up the difficulty.
More anatomy, more procedural steps, and greater complexity - designed to challenge surgeons who are ready to move beyond the basics and start connecting the dots.
Class IV
Where simulation starts to feel real.
Class IV delivers a full end-to-end procedure with extremely realistic tissue behaviour and anatomy.
The gap between simulation and reality starts to close here.
Class V
Hyper-realism. Tissue that is life-like.
Class V models feature full anatomy, full disease state, and end-to-end procedural training on tissue that is as close to human as synthetic can get.
Some models bleed. All of them perform. This is elite simulation.
