MRI-Guided Laser Ablation Epilepsy Surgery with Medtronic - Visualase | Beta Clinic Bonn

At the neurosurgical teams at Beta Clinic Bonn, MRI-guided laser ablation with the Medtronic VISUALASE™ system is offered as a minimally invasive epilepsy surgery option for selected patients whose seizures arise from a well-defined epileptogenic focus. The approach is designed as an alternative to open resective procedures, targeting the seizure-generating tissue with laser energy under continuous MRI guidance to treat the focus while minimizing impact on surrounding brain structures. The treatment is organized around precise lesion localization and stereotactic planning: the target zone is first defined using MRI, then a stereotactic approach is used to place a laser catheter through a very small skull opening into the planned target. During ablation, temperature changes and treatment effects are monitored in real time using MRI-based thermal monitoring, and built-in safety controls help protect adjacent healthy tissue. Many patients can be discharged the same day after treatment.
