Catalog Number: MT-LPP
As the newest member of the Guideline 4000™ family, the microTargeting™ Guideline 4000 LP+™ Neuromodulation Targeting System features the power of the Guideline 4000™ in a light, portable package.
The microTargeting™ Guideline 4000 LP+™ offers neurosurgical teams the power of the Guideline neuromodulation targeting family in a compact, streamlined package. The entire LP+ system fits into a single padded, lockable shipping case, making transport simple and convenient. Alternatively, the LP+ system can be permanently installed on an ergonomic cart with a locking cabinet and adjustable tabletop height. Modular by design, the LP+ can be configured to meet the specific needs of the customer, including user-specifiable channel count and optional drive accessories. The LP+ places a priority on meeting the clinical requirements of a targeting system, offering one-click recall of user preferences, side-by-side review of all recorded snapshots, and fully integrated stimulation and impedance check capabilities. Still, with independently-adjustable filter settings, ultra-wideband recording capabilities, and dedicated earth-referenced analog outputs for all channels, the LP+ can support the highest-powered research endeavors. Further, by providing seamless data export to MATLAB and NeuroExplorer, the LP+ enables users to create and run customized data analysis scripts, online or offline. Featuring simplified software and streamlined hardware, the LP+ is the latest generation of Guideline power, with an even stronger emphasis on reliability and usability.
