Catheters

Question 1

Core stiffness - Medium

Coating – Teflon

Tip – J 3-15 mm

Features - All-purpose wire for navigating large to medium vessels, abscess cavities, etc. J tip is atraumatic and lumen seeking.

Answer 1

Newton

Question 2

Core stiffness - Stiff

Coating – Teflon

Tip – J-15 mm (short taper)

Features- Useful for visceral artery exchanges where extra (short support needed, e.g., obese patients, tortuous taper) vessels, stiff catheters. Typically, 175 cm to 180 cm long, 0.035-in. to 0.038-in. diameter

Answer 2

Rosen

Question 3

Core stiffness – Very stiff

Coating – Teflon

Tip – Straight with floppy tip

Features- Very floppy, long straight tip good for crossing with small, tortuous vessels or stenosis.

Answer 3

Bentson

Question 4

Core stiffness – Very stiff

Coating – Teflon

Tip – Straight with relatively soft tip

Features- May be used cautiously to guide large, stiff with catheters such as angioplasty balloons, stents, or relatively IVC filters, and for catheter exchanges.

Answer 4

Amplatz

Question 5

Core stiffness – Soft to Stiff

Coating – Hydrophilic

Tip – Straight or angled

To guide the catheter into place during CVC (central venous catheter) insertions.

Answer 5

Glidewire

Question 6

Core stiffness – Soft to Stiff

Coating – Teflon / Hydrophilic

Tip – Shapeable

Features - Used with low-profile “tibial” balloons or coaxial catheters. 0.010-in. to 0.018-in. diameter, made of steel, platinum, or nitinol

Answer 6

Steerable
