SUSy – Stereotactic Ultralight System

Experience Versatility and Innovation: Frame the Future of Stereotaxy with our new Stereotactic System

inomed continues to be convinced of the advantages and benefits of frame-based stereotactic neurosurgery and is committed to its further development.

To follow our conviction, we have invested in the future of stereotaxy and redesigned the most important part of our portfolio – our stereotactic arc.

Our ultimate goal: support of the entire spectrum of stereotactic procedures.

Our new SUSy – Stereotactic Ultralight System combines the strengths of our previous stereotactic arcs and incorporates innovations based on clinical opinion. The innovative material results in a lightweight system that opens up new possibilities for MRI-based workflows. 

Developed for the highest demands

Carbon fibre reinforced PEEK

Originally developed for space travel, the diamond-milled new material of the stereotactic frame meets the highest stability requirements

Optimised resistance

  • PEEK is resistant to chemicals during cleaning
  • Resistant to high temperatures and X-rays
  • Artefact-free and transparent for CT and X-ray
  • Non-metallic and therefore suitable for the MRI environment

Durable & functional
High wear resistance with optimum sliding properties

Ultralight weight
The weight of less than 2 kg increases handling and patient comfort



for intraoperative position control


Vernier allows setting accuracy of 0.1 mm


Intuitive workflow

  • No mounting tool necessary
  • Fine adjustment by means of silicone rolls
  • Drumstop: Easy folding out and back of the arc into the surgical field

Freedom in the trajectory

  • Cartesian coordinates a, b, c and angles d and e
  • Four different mounting options on the ring

Two-point fixation for maximum stability
Two-piece ring adaptation maintains sterile barrier with multiple mounting


Versatile in use

Innovative in application based on clinical opinion.
A large portfolio of accessories opens up countless possibilities and universal use in modern stereotaxy. 

Deep brain stimulation

In deep brain stimulation (DBS), electrodes are implanted in specific areas of the brain to treat primarily movement disorders with electrical impulses. The target areas are very small structures, which is why these interventions require the highest precision.

The inomed MicroDrive with a resolution of 50 μm and tacticle feedback with each rotation has been specially developed to meet the demands.

The inomed MER system >> for microelectrode recording and test stimulation completes the portfolio for deep brain stimulation. 


A biopsy is performed when surgical resection is not safely feasible, e.g. due to the location of the tumour or the impaired clinical condition of the patient.

Interventions in the posterior cranial fossa are particularly difficult trajectories to plan due to the special access. The perfect interaction of the head ring unit and SUSy offers maximum flexibility to plan these trajectories collision-free.

inomed offers a comprehensive range of sophisticated biopsy instruments for intraoperative stereotaxy.

Stereo-EEG (sEEG)

The recording of EEG signals with stereotactically placed depth electrodes is used for the diagnosis of drug-resistant epilepsy. For this purpose, mainly lateral trajectories are chosen. The AP mounting enables these trajectories to be carried out unconditionally and safely.
