MRI-Guided Laser Ablation
Visualase® provides advanced MRI-guided laser ablation technology for thermal ablation markets, including neurosurgery. Laser energy is delivered to the target area using a laser applicator. As light is delivered through the laser applicator, temperatures in the target area begin to rise, destroying the unwanted tissue.7
Because Visualase procedures are guided by MRI images, the procedure can provide precise ablation. Due to the minimally invasive nature of the procedure, hospital stays have been reported to be reduced compared to open procedures.1-6,8-11
The Visualase MRI-Guided Laser Ablation System is indicated for use as a minimally invasive procedure to ablate, necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy under magnetic resonance imaging (MRI) guidance for wavelengths 800nm through 1064nm in cranial neurosurgery.
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, temperature in the target area rises. Real-time MRI thermographic imaging clearly maps tissue temperature changes, providing you precise control of the tissue ablation.
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
Visualase is the only system with 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.
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 flexibility when starting your laser ablation program and is designed for easy upgrades.
VISUALASE MOBILE CART SYSTEM
The Visualase cart-based system provides flexibility and mobility.
The Visualase system supports a workflow that addresses the unique challenges of performing a procedure within the MRI bore.
