Realism

Your fingertips
know the real thing.

  1. 01The resistance as the needle passes through
  2. 02The tenacity of the vessel wall
  3. 03The nonlinear elasticity of living tissue

Proprietary decellularized tissue, produced with ultra-high hydrostatic pressure.

In tactile feedback during needle passage and in suture-handling characteristics, it reproduces living tissue so faithfully that it is virtually indistinguishable from it.
