The Intended Purpose of Leksell® Vantage™ Stereotactic System is target localization and fixation of the patient head in a coordinate system in order to perform stereotactic neurosurgical procedures, for example; deep brain stimulation, lesioning, biopsies, targeted injections, aspirations and minimal invasive tumor treatments.

The Leksell® Vantage™ Stereotactic System is a device used for minimally invasive neurosurgical procedures. It enables coordinate referencing and fixation of the patient's skull and brain during image acquisition and treatment. The coordinate referencing enables target localization and accurate stereotactic treatment of brain targets; for example for aspirations and biopsies, electrode placements, injections of cells & drugs, heamatoma evacuations as well as lesioning using a number of methodologies. The system consists of a head frame that is fixated to the patient skull by minimally invasive disposable fixation pins and a number of accessories for frame application and imaging as well as a stereotactic arc and operating room accessories for the sterile surgical procedure. The system is based on the established Leksell center-of-arc principle, which allows guidance of compatible interventional instruments at any trajectory angle to the brain target. Compatible interventional instruments are based on the Leksell principle of an active working length of 190 mm (as the arc radius) and use the correct mechanical interfacing of the Arc instrument stop and guide holders. Various instruments, such as biopsy needles, cannulas, and electrodes can be used with the system to perform biopsies, hematoma evacuation and injections of radioactive nuclides and cytostatic agents, puncture of cysts, positioning electrodes for stimulation/ recording or lesioning and stereotactic endoscope guidance.

Leksell Gamma Knife® Icon™ and Leksell Gamma Knife® Perfexion™ are radiosurgery systems for use in the stereotactic irradiation of head structures. Surgery is achieved by delivering a prescribed dose as one or more shots of ionizing radiation to the exact site of the target. Based on preoperative radiological examinations, the Leksell Gamma Knife unit provides highly accurate external irradiation of intra-cranial structures using collimated beams of ionizing radiation.

Leksell GammaPlan® is a computer-based system designed for Leksell Gamma Knife® treatment planning.

Leksell GammaPlan® is designed for use with the Leksell Gamma Knife and is intended to be used for planning the dosimetry of treatments in stereotactic radiosurgery and stereotactic radiation therapy. It processes the inputs of health care professionals (e.g. neurosurgeons, radiation therapists, radiation physicists) such that the desired radiation dose is delivered by the Leksell Gamma Knife to a precisely defined volume.
