QUESTIONS AND CORRECT DETAILED
ANSWERS (VERIFIED ANSWERS) |ALREADY
GRADED A+
Name the benefits If a guidewire core extends all the way to the
tip - CORRECT ANSWER-1. The tip tends to be more
DURABLE
2. Gives the user BETTER TACTILE FEEDBACK
Name the benefits if a guidewire core DOES NOT extend all the
way to the Tip - CORRECT ANSWER-1. The wire is more
FLEXIBLE
2. The wire tip is softer and easier to SHAPE
Name 2 potential drawbacks if a guidewire core DOES NOT
extend all the way to the tip. - CORRECT ANSWER-1. The tip
is more DELICATE
2. The guidewire is more likely to PROLAPSE

PTFE is a common Coating used on the OD of Guidewires.
Is it Hydrophilic or Hydrophobic?
What are some benefits of using a PTFE coating on the OD of a
Guidewire? - CORRECT ANSWER-1. Hydrophobic (repels
water)
2. It reduces FRICTION and IMPROVES TRACKABILITY
and gives the user better TACTILE FEEDBACK
A guidewire that has a core that extends all the way to the tip
and has a Hydrophobic coating on the OD will have
___________ tactile feedback - CORRECT ANSWEREXCELLENT
Compared to Hydrophobic-coated guidewires, HYDROPHILIC
coated guidewires have (MORE/LESS) TACTILE FEEDBACK
- CORRECT ANSWER-LESS TACTILE FEEDBACK
Compared to Hydrophobic-coated guidewires, HYDROPHILIC
coated guidewires have (BETTER/WORSE) TRACKABILITY
in Tortuous vessels AND DRAG - CORRECT ANSWER-

3 | P a g e
BETTER TRACKABILITY in tortuous vessels and LESS
DRAG
How does a LONG TAPERED CORE affect:
Trackability?
Support? - CORRECT ANSWER-IMPROVES IT
IMPROVES IT
As the distance between a guidewire tip and a torque device
increases, what happens to the torque response of the wire -
CORRECT ANSWER-The Torque Response goes down
What effect does vessel tortuosity have on the Torque Response
of a guidewire? - CORRECT ANSWER-As Tortuosity
INCREASES, the Torque Response of the guidewire
DECREASES
How does a LONG TAPERED CORE affect:
SUPPORT?
