Two types of embolectomy catheters are available: LeMaitre natural latex balloon catheters and NovaSil® latex-free balloon catheters. Single lumen catheters use hand-tied balloons that are glued in three areas and pre-stretched for flexibility. These catheters are strong and able to withstand a substantial force before the balloon disengages from the catheter. Balloons are well-centered and resistant to rupture.
Over-the-Wire embolectomy catheters are also available. These allow for the addition of contrast media to facilitate imaging during fluoroscopy.
- Radiopaque for visibility under fluoroscopy
- Constructed of pliable material for introduction and passage through vessels that may be difficult to navigate
- Color-coding for catheter size identification
- Long shelf life for sterility
Strength: catheter material is strong, allowing the catheters to withstand a substantial force before the balloon disengages.
Resistant to rupture: balloons are manufactured to high specifications so that they are resistant to rupture during contact or trauma.
Predictable inflation: the balloons inflate at a consistent rate as the volume of the balloon increases.
Centered balloons: each balloon is centered on the catheter shaft for concentric inflation and deflation.
Dye contrast: contrast media can be added to better visualize the catheter under fluoroscopy.
Positioning: standard guidewire capability of the over-the-wire catheter allows for proper positioning of the catheter in the vessel.
Irrigation: lubricate with fewer passes and less intimal trauma during catheter withdrawal.
Silicone balloons: balloons can be used in patients with latex allergies because they do not contain latex.
Concentricity: like the latex catheters, the balloons are centered on the catheter to reduce potential damage to the vessel intima.
