Question 3

Both FineCross MG & M3 are indicated for use in coronary arteries and for contrast injection. What space is M3 not indicated in?

Answer 3

Peripherals or cerebral vessels

Question 4

What is the distal tip Fr for both FineCross MG & M3?

Answer 4

MG = 1.8Fr
M3 = 1.7Fr

Question 5

What is the distance between the gold radiopaque marker and the distal tip of both the MG & M3 FineCross microcatheters?

Answer 5

MG = 0.7mm
M3 = 1.3mm

Question 6

What length is the floppy segment on both the MG & M3?

Answer 6

MG = 13cm
M3 = 15cm

Question 7

How long is the hydrophilic coating on the 150cm MG & M3?

Answer 7

MG = 90cm
M3 = 95cm

Question 8

What is the taper on the M3 microcatheter?

Answer 8

1.8Fr to 2.5Fr

Question 9

What are the primary 4 differences between the FineCross MG vs. M3?

Answer 9

1. Smaller 1.7Fr distal tip for better handling & crossability
2. 2x longer tip distance from marker to distal tip for better visibility & tracking
3. 2cm longer floppy segment for better tracking
4. M3 hydrophilic coating for enhanced lubricity

Question 10

Answer 10

Cerebral

Question 11

What are the primary components of the PriorityOne system?

Answer 11

catheter
pre-loaded stylet
extension line w/stopcock
syringes (2)
filter basket
flushing tool

Question 12

What are the 3 KEY benefits of PriorityOne?

Answer 12

1. Deliverability via SS braided shaft + SS stylet
2. Easy Aspiration via large aspiration lumen + short, round & flexible tip
3. Ease of Use via easy 2-step setup & distal radiopaque marker

Question 13

True or False: PriorityOne is the only in-service & drop product that we carry due to the emergent/acute nature of its’ use.

Answer 13

TRUE

Question 14

Aspiration Catheters are used in what clinical applications?

Answer 14

Localized thrombus formation and Myocardial Infarction (Heart Attack)

Question 15

How can you differentiate thrombus from stenosis in images?

Answer 15

It will act like a sponge under live fluoro and appears fuzzy/hazy/grainy on angios.
