Leksell® Neuro Generator
Overview
One for all
All the functionality you need
Leksell® Neuro Generator now adds pulsed RF to the wide range of available functions. It offers
very high functionality in a compact package that is easy to learn and effective to work with.
One Fully Integrated System
Together with customized electrodes and cannulas,
Leksell® Neuro Generator provides excellent flexibility
and versatility. It is the only neurogenerator to be fully
integrated with Leksell Sterotactic System®.
Versatility Delivered
Leksell Neuro Generator is a complete system designed
for a wide range of treatment techniques and therapies,
including:
• Impedance measurement
• Macro stimulation
• Continuous RF treatment
• Pulsed RF treatment
• Stereotactic brain lesioning
• Bipolar coagulation
Unique Capabilities
• Th
e Active Tissue Characterization feature further
improves performance for delicate treatment. The
instrument automatically tests specific tissue response
to small amounts of current before each treatment.
It then optimizes parameters accordingly, enabling
safer treatment and a better outcome for the patient.
• The remote control is another unique feature. Used
for macro stimulation, it allows the clinician to closely
follow the patient’s reactions.
• Leksell Neuro Generator can be safely and effectively
operated while fully draped under full sterile conditions.
Easy to Understand, Easy to Use
Leksell Neuro Generator offers a user-friendly interface
with multifunctional keys, compact size and remotely
controlled features, allowing the clinician to
work closer to the patient. All stimulation
parameters are continuously monitored
and adjustable. The temperature bar graph
shows both set and current temperature,
as well as rate of change.
The System that Matters – for Patients
Leksell Neuro Generator is a comprehensive
solution that aids neurosurgeons and
anesthesiologists in improving safety and
quality of life for patients through a unique
range of advanced features.
Proven Technology
Leksell Neuro Generator is based on well-proven
technology. It offers a number of important safety
features, such as the unique Active Tissue
Characterization, and protection against overload
and overheating. Thermocouple sensor-controlled
electrodes provide additional protection.
Specific electrodes for each particular task
A wide range of specially designed monopolar and bipolar electrodes are available for applications such as impedance
measuring, macro stimulation, brain lesioning and pulsed RF treatment. The brain lesion electrodes are specifically
designed to work smoothly with the Leksell Stereotactic System®.
Brain Lesion Electrodes
Easier DBS electrode implantation
Elekta MicroDrive Bipolar Macro Electrode is used for
target localization, verification and lesioning. It is designed
for use with Elekta MicroDrive™ when determining
the correct target for DBS electrode implantation and
lesioning. When performing lesioning, the electrode is
supported by the high accuracy of Elekta MicroDrive™.
Accurate Lesioning and Stimulation
Brain lesion electrodes are intended for impedance
measurement, macro stimulation and lesioning. They
are used for target localization and verification, as well as
for stereotactic brain lesioning. The electrodes are either
monopolar, bipolar or dual monopolar. All are using Leksell
Stereotactic System®. They have integrated thermocouplecontrolled temperature measurement and are fully steam
autoclavable and reusable. The wide offering of electrodes
enables the most optimal treatment for each patient.
Electrodes and Cannulas for RF Treatment
Specialized Electrodes for Safe Lesioning
The customized DREZ electrode has a specialized design
that ensures only the tip of the electrode penetrates the
target. The depth of the penetration is assured by the
shoulder of the electrode insulation, which stops the
electrode from penetrating deeper than 2 mm.
Cannulas for Easy Access
The cannulas are designed for use with the customized
thin RF electrodes. They are straight or curved, equipped
with a sharp or blunt tip, and provided in many different
tip lengths. The cannulas offer easy access and guidance
through the tissue and are intended for single use.
Optimal RF Lesioning or Pulsed RF Treatment
These thin electrodes are specifically designed for use
with dedicated subcutaneous cannulas. They are available
in three lengths with a wide range of cannulas to meet
various needs. All have integrated thermocouplecontrolled temperature measurement and are fully steam
autoclavable and reusable.
