What are 5 catheters used in IR
diagnostic angiographic catheters, microcatheters, drainage catheters, balloon catheters, and central venous catheters
What are the factors to consider when deciding on the use of a diagnostic angiographic catheter
these include size (the smaller the better for access but size limits the lumen), shape, radiopacity, torque capacity, and softness of the distal tip
Can a diagnostic angiographic catheter be used as a guiding catheter for microcatheters or angioplasty balloon
yes
What is the size of a microcatheter
3 french or smaller
What are microcathers designed for
very distal catherization
What is the size of the guide wire for a microcatheter
These catheters are placed over 0.010- to 0.018-inch guide wires
What are microcathers primarily used to do
neurointerventional cases
peripheral intervention for small vessel embolization or infusion
What are some types of drainages that a drainage catheter is used for
of fluid collections, abscess, biliary gallbladder, pleural fluid, ascites, and lymphoceles.
What is the size of a drainage catheter
shape is usually based on the size of the fluid collection for drainage and the retention property.
Is a pigtail catheter a type of drainage catheter
yes
What are the most common retention devices for drainage catheters
3
sutures
mushroom tip
inflatable ballon
What are 3 types of balloon catheters
oclussion balloons
embolectomy balloon
angioplasty balloons
What is a characteristic of a occlusion balloon
soft and pliable.
What is another name for an embolectomy balloon
fogarty balloon.
What does an embolectomy balloon look like
What are the 2 main categories of embolectomy balloon catheters
Balloons for dilation can be divided into two main categories regarding the size of guide wire over which they are placed: 0.018 inch (or even smaller, including 0.014 inch) and 0.035 inch
What is most common balloon catheter
the ones placed over the 0.035 inch
Do large balloons require the use of an introducer sheath
Large balloons require large access sites (introducer sheaths), especially for removal after inflation, as they do not re-wrap very well.
What is the sequence of events for angioplasty
an introducer sheath then a guid wire and then a cathether in the introducer sheath but over the guide wire

What are the primary characteristics of guidewires
length, diameter, tip configuration, torqueability, stiffness, and composition
What are standard guidewires made of
Standard guidewires are made of a stainless
steel coil wrapped tightly around an inner mandril that
tapers at the working end of the wire.
When are hydrophilic guidewires useful
diseased or tortuous vessels
What are the standard guidewire diameters
0.035 and 0.038
What is the diameter of smaller guidewires
0.014 and 0.018
When are the smaller diameters wires used
microcatheters adnd small caliber needles
What is the length of a standard guide wire
125-145cm
What are longer wires called
exchange wires
What are catheters made of
polyurethane, polyethylene, nylon or teflon
What is done so a catheter is more torqueable
wire braiding
What is done to a catheter to make it more trackable
coating with a hydrophilic polymer
How big is 3 french
1mm
What does french refer to
the outer catheter diameter
What are 3 types of catheters
straigh catheter
reverse curve catheters
pigtail-type catheter
Can a straight catheter be reshaped
yes, if it is non-braided it can be reshaped by heating them under a steam jet
What are 6 types of catheters available
straight catheters
reverse curve catheters
pigtail catheters
sheath
guiding catheters
microcatheters
What is the function of a sheath
thin walled valved supportiong caheter placed when there is persistent oozing or hematoma at
the access site, multiple catheter exchanges are expected,
a prolonged procedure is anticipated, or vascular
intervention is planned
Can contrast be injected through the side arm around guidewires or non-occlusive catheters when a sheath catheter is being used
yes
How big is a sheath catheter compared to its stated french size
outer sheath diameter is 2 sizes larger than the stated french size
What is a guiding catheter
allow safer more secure passage of device into a vessel (renal arter stent) these are inserted through a larger sheaths at the vascular access site
What is a microcatheter
are placed through standard angio-
graphic catheters to allow entry into small or tortuous
arteries. They are guided by small-caliber (e.g., 0.014 to 0.018 inch) steerable guidewires.
What are the indications for pressure measurement
Intravascular pressure monitoring is primarily used to
determine the hemodynamic significance of stenoses, assess
the results of revascularization procedures, and diagnose
pulmonary artery or portal venous hypertension.
What are the commonly used guidewires
What does a straight catheter look like
