Brief summary
This will be an open-label, pilot, exploratory, single centre clinical investigation. This is an early feasibility single arm study. No formal hypothesis is proposed. A total of up to 15 evaluable subjects receiving a non-radical ablation is planned. The safety and feasibility outcomes will be measured directly post-treatment, 48h and 3 months post-treatment. A minimal invasive neurosurgical approach with a Magnetic Resonance Imaging (MRI)-based stereotactic guidance system will be utilized for the planning, navigation, intracranial access, placement and confirmation of the Laser applicator prior to ablation.
Interventions
DEVICETRANBERG® laser applicators when used in MR-guided laser thermal ablation of brain lesions using the TRANBERG® Thermal Therapy System and TRANBERG® Thermoguide Workstation.
The main purpose with the study is to investigate safety and feasibility of the TRANBERG® laser applicators when used in MR-guided laser thermal ablation of brain lesions using the TRANBERG® Thermal Therapy System and TRANBERG® Thermoguide Workstation together with SmartTwist™ MR Hand Drill with the SmartTip™ MR Drill Kit for MR-guided laser thermal ablation of brain lesions.
