Spectranetics manufactures and markets the only excimer laser system and disposable catheters for the treatment of peripheral and coronary arterial disease and lead extraction and management.
The Science of Excimer Laser Ablation
Photoablation is the use of light to break down, vaporize and remove matter. Spectranetics CVX-300® Excimer Laser facilitates photoablation via a variety of Spectranetics catheters to remove binding scar tissue surrounding cardiac pacemaker ICD leads.
The mechanisms of actions are:
Photochemical: Breaking molecular bonds
1. UV light pulse hits tissue for 135-billionths of a second (135ns); the duration of the laser pulse
2. 50 microns penetration
3. Billions of molecular bonds fractures per pulse
4. After 135-billionths of a second, laser energy is not emitted
Photothermal: Producing thermal energy
1. Absorption vibrates the molecular bonds of the plaque
2. Vibration of bonds heats intracellular water
3. Water vaporizes, molecules break apart, and cells rupture
4. Expanding vapor bubble forms in 100-millionths of a second (100 µs)
5. 1,000 times the duration of the actual laser energy emission
Photomechanical: Creating kinetic energy
1. Expansion and collapse of vapor bubble breaks down tissue and clears byproducts away from tip
2. Byproducts of ablation are water, gas, and small particles
3. Entire process time per pulse is 400-millionths of a second (400 µs)
4. 4,000 times the duration of the actual laser energy emission
When removing the lead is the right choice, choose the Spectranetics Lead Locking Device (LLD®) and make it EZ!
LLD EZ® combines the best of the original LLD family and enhanced tip design with new ease-of-use features to provide a flexible traction solution for leads targeted for removal today.
LLD EZ accommodates a wide range of leads with inner lumen diameters from 0.015″ (0.38mm) to 0.023″ (0.58mm).
EZ Locking and Unlocking
Only Spectranetics’ Lead Locking Device technology provides a stable traction platform by deploying a braided mesh to lock securely along the entire lead lumen. LLD provides proven1 capability to unlock and reposition after initial deployment.
Flexible platinum-iridium tip design and sleek profile facilitate tracking and passage through tightly curved leads and past some points of lead lumen damage.
Highly visible radiopaque marker assists identification of LLD EZ tip location under fluoroscopy.
Safely and efficiently removing leads depends on tools that give you versatility and control. GlideLight laser sheath offers the unprecedented ability to customize the laser’s repetition rate throughout a procedure. At 80Hz, the GlideLight laser sheath requires up to 55% less advancement force,¹ and advance up to 62% more efficiently through tough binding sites than SLS II.²
