What is the difference between guide catheter and diagnostic catheter?
Guides have a shorter, more angulated tip and a larger internal diameter than similar diagnostic catheters. The larger internal diameter facilitates equipment delivery and contrast injection.
What is a guide catheter?
The guide catheter provides support for device advancement (stents, balloons, etc.). It is the conduit for device and wire transport, a vehicle for contrast injection and takes measurements. Guide catheters are available in a variety of shapes and sizes to fit a variety of patient anatomies.
What is launcher guide catheter?
Product Description Medtronic Launcher Guiding Catheter is used in a therapeutic procedure to treat the narrowed or stenotic section of the coronary artery of the heart due to coronary atherosclerosis. The guide catheter provides support for device advancement (stents, balloons, etc.).
What is a guide extension catheter?
GUIDEZILLA II Guide Extension Catheter creates a smooth pathway for balloon and/or stent delivery by providing greater flexibility and a smooth surface. This is important with complex lesions, calcium, tortuous vessels, and distal lesions.
Do guide catheters have wire braiding?
Guide wires come in two basic configurations: Solid steel or nitinol core wires and solid core wire wrapped in a smaller wire coil or braid. Coiled or braided wires offer a large amount of flexibility, pushability and kink resistance.
What are guide wires and catheters?
Abstract. Guidewires and catheters are used during minimally invasive interventional procedures to traverse in vascular system and access the desired position. Computer models are increasingly being used to predict the behavior of these instruments.
What is a guide sheath?
Destination Guiding Sheath is designed to perform as a guiding catheter and an introducer sheath. Destination is designed to be used for the introduction of interventional and diagnostic devices into the human vasculature, including but not limited to the lower extremities, renal arteries, and carotid arteries.
How do you engage an EBU guide?
The best view to engage an EBU catheter is LAO 45 or LAO caudal view. The basic methods to engage the EBU GC to LM ostium is the “rotating and pulling” or “Advancing and forming U shape”.
What is a GuideLiner?
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.
What is a trap liner?
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.
What is a guide wire made of?
Guidewires are either solid or braided and composed of steel or an alloy of nickel and titanium, nitinol.
What is PTCA guide wire?
GUIDE WIRES are intended to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA).
How does guide wire work?
Tiny guide wires are designed to navigate vessels to reach a lesion or vessel segment. Once the tip of the device arrives at its destination, it acts as a guide that larger catheters can rapidly follow for easier delivery to the treatment site.
How do you pull a sheath?
The Correct Way to Pull a Sheath
- Take your index, middle and sometimes your ring finger, and place them slightly above the sheath to feel the patient’s pulse.
- Slowly remove the sheath in a sterile manner, holding occlusive pressure to avoid bleeding.
What is catheter sheath introducer?
A “sheath” or “introducer” refers to any line (arterial or venous) that contains a port allowing a proceduralist to “introduce” (hence the name) transvenous pacing wires, Swan Ganz catheters, intravascular ultrasound (IVUS), intra-aortic balloon pumps, single lumen infusion catheters (“SLICs”), etc.
How do you engage an RCA?
In order to engage the SVG-to-RCA, the catheter is positioned above the level of the RCA, then pulled with a counterclockwise rotation. As opposed to what may make intuitive sense, counterclockwise torquing is used to engage the SVG-to-RCA rather than clockwise torquing.
