Begin with an anesthetized human patient with an exposed skull. The patient is diagnosed with an intracranial tumor.Drill into the exposed skull to create a hole, generating an access point.Using stereotactic guidance, insert a laser diffusing fiber or LDF along the predetermined path and secure it in place.Transfer the patient to an MRI scanner and connect the LDF to a laser source.Capture MRI images from multiple angles to visualize the fiber path and the tumor.This confirms the LDF’s...

2016
A protocol to detect and automate mode locking in a pre-adjusted nonlinear polarization rotation fiber laser is presented. The detection of a sudden change in the output polarization state when mode locking occurs is used to command the alignment of an intra-cavity polarization controller in order to find mode-locking conditions.
FAQs
The laser fiber delivers controlled thermal energy to the vein wall. This heat damages the wall, causing the treated vein to collapse and seal rather than remain open to blood flow. Once closure occurs, blood is redirected through healthier veins. This targeted response addresses the abnormal vessel while limiting disruption to surrounding tissue.
Ultrasound guidance helps clinicians identify the target vein and monitor placement of the thin laser fiber within it. This image-guided approach supports accurate delivery of thermal energy to the intended vessel. It also illustrates how visualization and targeted treatment work together in minimally invasive vascular care, rather than relying on surgical exposure of the vein.
Endovenous Laser Therapy closes the diseased vein using internally delivered thermal energy, whereas surgical vein removal requires greater tissue disruption. The less disruptive approach can reduce pain, swelling, and visible varicosities while supporting outpatient treatment. Its clinical value lies in treating the abnormal vessel without the broader tissue disturbance associated with surgical removal.
Clinicians first use ultrasound to identify the target vein and guide a thin laser fiber into position. They then deliver controlled laser energy along the diseased vessel, producing wall damage, collapse, and sealing. After closure, circulation shifts toward healthier veins. This sequence combines image guidance, focused thermal ablation, and a minimally invasive treatment approach.
The treatment is used most commonly for superficial veins affected by chronic venous insufficiency and varicose veins. It may be considered when diseased veins contribute to symptoms or visible changes such as pain, swelling, or prominent varicosities. The technique provides a targeted clinical option within outpatient vascular care while preserving flow through healthier veins.
By sealing the diseased vein and redirecting blood through healthier vessels, treatment can reduce pain, swelling, and visible varicosities. Its minimally invasive design also supports efficient outpatient vascular care with less tissue disruption than surgical vein removal. These outcomes demonstrate the practical value of combining targeted thermal ablation with ultrasound-based image guidance.
