Hardware components for SLAH using Visualase laser thermal therapy system using different ste-reotactic methods. (A) Fifteen-Watt 980-nm diode laser energy is directed along a 400-μm core silica optical fiber that terminates in a circumferential diffusing tip (red). This fiber optic is housed within a 1.65-mmdiameter saline-cooled polycarbonate cooling cannula (bottom). A threaded plastic bone anchor (top right) and stiffening stylet (middle) are used to stereo-tactically deliver the device to brain structures. (B) Stab incisions and 3.2-mm twist drill holes are made using a stereotactic headframe. Anchor bolts are threaded into twist holes under stereotactic control; Visualase laser applicators are passed through bolts, secured, and flagged with sterile adhesive strips. (C) Alternative direct real-time MRI-guided placement of Visualase laser applicator via an MRI guidance miniframe (SmartFrame, MRI Interventions, Irvine, CA) within an MRI suite.
