Visualase<br>MRI-Guided<br>Laser Ablation
For the ablation of soft tissue in neurosurgery
Visualase™ MRI-guided laser ablation system lets you monitor tissue ablation in real-time. It provides significant advantages to the patient:
The Visualase Thermal Therapy System is indicated for use to necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy under magnetic resonance imaging (MRI) guidance in medicine and surgery in cardiovascular thoracic surgery (excluding the heart and the vessels in the pericardial sac), dermatology, ear-nose-throat surgery, gastroenterology, general surgery, gynecology, head and neck surgery, neurosurgery, plastic surgery, orthopedics, pulmonology, radiology, and urology, for wavelengths 800 nm
The Visualase system uses a laser to destroy unwanted soft tissue. Light energy is delivered to the target area using a small laser catheter. As the laser light is delivered,
Live MR thermometry lets you monitor tissue ablation in real time. With simultaneous, multiple plane monitoring and the ability to superimpose MR thermometry and thermal damage estimate maps, you can define and monitor the ablation zone, giving you the precision you need to deliver the results you expect.9-10
The Visualase system features easy-to-set temperature checkpoints for added confidence when ablating near critical structures. You can set checkpoints on either screen and in any plane. If temperature limits are hit, the laser immediately shuts off, preventing unwanted damage.
A small, 1.65 mm flexible catheter and shallow bone anchor provide broad surgical access. There is no need to sacrifice surgical trajectory or imaging coil selection due to laser design or patient positioning. The 360⁰ diffusing laser tip permits individual ablation times of only a few minutes.11,12 The in-plane thermometry approach eliminates readjustment of the MRI acquisition planes for a streamlined procedure.
VISUALASE CATHETER
The 1.65 mm Visualase flexible catheter provides broad surgical access.
The Visualase system’s mobile cart design facilitates movement between magnets and readily connects to your MRI with a standard Ethernet cable. The mobility of the system offers unmatched flexibility when starting your laser ablation program and is designed for easy upgrades.
VISUALASE MOBILE CART SYSTEM
The Visualase cart-based system provides unparalleled flexibility and mobility.
The Visualase system supports a workflow that addresses the unique challenges of performing a procedure within the MRI bore.
