LaserBLOCK fiber optics form a core component of the INVAMED LaserBLOCK Varicose Vein Laser System, engineered to deliver laser energy consistently along the length of an incompetent vein during endovenous laser ablation (EVLA). Fiber design plays a significant role in how energy is distributed to the vein wall, which is why INVAMED offers multiple fiber configurations within the LaserBLOCK platform.
What Fiber Configurations Does LaserBLOCK Offer?
According to INVAMED's product documentation, the LaserBLOCK system offers bare-tip, radial-tip, and jacketed single-use fiber options. Fiber diameters generally range from approximately 400–600 µm for bare fibers up to roughly 600–800 µm for radial fibers, giving physicians a choice depending on vein caliber and procedural preference.
These fibers are designed to be single-use, which is intended to support consistent performance characteristics and reduce variability that could arise from fiber reuse.
Why Does Fiber-Tip Design Matter?
The physical design of the fiber tip determines how laser energy is emitted into the vein. INVAMED describes its fiber technology as featuring a "high-purity fiber design" with radial or bare-tipped configurations intended to "promote even energy distribution, ensuring consistent vein wall shrinkage and lower risk of perforation or focal overheating."
Radial-tip fibers emit energy circumferentially around the tip, which is intended to distribute thermal energy more evenly across the vein wall's circumference compared to a purely forward-facing bare-tip design.
How Does Fiber Selection Relate to Wavelength?
LaserBLOCK fibers are offered alongside multiple wavelength configurations, including 810 nm, 940 nm, 980 nm, and 1470 nm, depending on the variant selected. Physicians can pair fiber type with an appropriate wavelength based on individual vein anatomy, consistent with the device's Instructions for Use.
What Should Physicians Know Before Selecting a Fiber Type?
Fiber selection is generally considered alongside other procedural variables, including:
- Vein diameter and tortuosity
- Wavelength being used
- Physician training and procedural preference
- Manufacturer-specified contraindications, such as veins too tortuous or large for effective fiber navigation
As with any endovenous device component, appropriate fiber selection is determined by the treating physician in accordance with the product's Instructions for Use and individual clinical judgment.
Frequently Asked Questions
Are LaserBLOCK fibers reusable?
LaserBLOCK fibers are designed as single-use components, consistent with standard practice for endovenous laser fibers used in sterile percutaneous procedures.
What is the diameter range of LaserBLOCK fibers?
Bare-tip fibers generally range from approximately 400–600 µm in diameter, while radial-tip fibers range up to approximately 600–800 µm, according to INVAMED product documentation.
Can physicians choose between bare and radial fibers on the same console?
The LaserBLOCK platform offers both bare-tip and radial-tip fiber options across its wavelength configurations, allowing physicians to select the appropriate fiber type per the device's labeling and clinical scenario.
