Continuous feedback-controlled heating of the vein to 85oC optimizes endothelial destruction, collagen contraction, vein wall thickening and results in vein occlusion.
Temperature controlled heating of the vein wall causes:
- Shortening and thickening of collagen fibers
- Vein lumen diameter shrinkage
- Fibrotic sealing of the vessel
