DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+||LATEST EXAM!!!
Which type of Guidewire Core design provides better
Trackability? - ANSWER-A long, gradual taper
An advantage of a more proximal taper is improved
_____________________ of the wire - ANSWER-
trackability
How are guidewires SIZED (Scale) - ANSWER-INCHES
for OD
Centimeters for LENGTH
Measured at the OD of the guidewire
T or F Hydrophilic Guidewires are LESS Thrombogenic
than Non-hydrophilic guide wires - ANSWER-TRUE
Non-hydrophilic guidewires can be wiped down with
Heparinized saline to reduce risk of what? - ANSWER-
Thrombus formation around the wire

All CORONARY guidewires come in what range of sizes?
What is the most common diameter for a Coronary
guidewire? - ANSWER-All coronary guidewires come in a
range of overall diameters (0.010″-0.018″),
The most common diameter being 0.014″.
3 main types of Guidwires - ANSWER-1. Access wires
2. Maneuver wires
3. Rail wires
How is an Access wire used - ANSWER-It is used at the
beginning of a procedure.
After access is obtained with a needle, an Access Wire
is advanced to the targeted vessel or structure.
Once the Access Wire is in place, the needle can be
exchanged for a sheath, dilator, or catheter.

How are maneuver wires used - ANSWER-They are used
to navigate throughout the vasculature and sub-select
target vessels or structures
Describe the construction of a RAIL WIRE - ANSWER-
Tend to be stiffer wires used for equipment exchanges
Tend to have floppy tips to aid in advancing heavier
devices
Most common RAIL WIRE - ANSWER-Amplatz (Boston
Sci)
Rosen (Cook Medical)
Why is it recommended that STIFF wires not be used in
curved vasculature? - ANSWER-A stiff wire can cause
vessel damage in these cases
What is the most common size guidewire used in
PERIPHERAL interventions? - ANSWER-.035"
.018" is the second most common size used
