What is a GuideLiner catheter?
The GuideLiner® catheter (Vascular Solutions Inc., Minneapolis, Minnesota, United States) is a coaxial “mother and child” catheter, mounted on a monorail system, that extends the angioplasty guiding catheter and enables deep intubation of the coronary artery to achieve extra support and improve coaxial alignment.
How does a GuideLiner work?
GuideLiner is shown with a protruding compliant 2.0 mm × 15 mm balloon. The balloon is then inflated to nominal pressure and then both the balloon and the GuideLiner are advanced into the vessel while anchoring the guidewire (Figure 1(b)). Once the GuideLiner is advanced to the target segment the balloon is deflated.
Who makes GuideLiner?
Vascular Solutions Inc.
As a “mother and child” system, the GuideLiner catheter (Vascular Solutions Inc., Minneapolis, MN, USA) provides an extension to the guide catheter with better coaxial alignment and stability. We report two didactic cases showing the usefulness of the GuideLiner device in everyday catheterization laboratory practice.
What is a guide catheter used for?
7F or 8F guide catheters are used for complex procedures requiring larger PCI devices (e.g., rotoblator) or simultaneous positioning of two stents for treatment of bifurcation lesions.
What is a TrapLiner?
The TrapLiner® Catheter is a rapid exchange guide extension catheter that combines the ability to provide backup support with the ability to trap a 0.014” guidewire.
How do you use a guide extension catheter?
BTT: A Balloon is placed in the coronaries downstream to the guide extension. It is then advanced by pushing it forward while holding the inflated balloon in place. When it reaches the balloon edge, it is deflated and the catheter is advanced over it. So the balloon invaginates completely into the guide extension.
What is the difference between guide catheter and diagnostic catheter?
Guide Catheter Characteristics Compared to the diagnostic catheters, the guiding catheters do not have tapered tips. They have thinner walls, larger lumens, and stiffer shafts (Fig. 1.3).
When would you use a microcatheter?
Microcatheters are small 0.70-1.30mm diameter catheters that are used for guidewire support, exchanges, to access distal anatomy, cross lesions, deliver therapeutic embolic, inject contrast media and perform other procedures in complex endovascular procedures.
How do you advance a microcatheter?
We could advance Corsair microcatheter by slowly rotating it clockwise by slowly rotating it clockwise. Finally, both the Corsair and guidewire could be advanced as far as the lesion could be advanced as far as the lesion.
