Tissue
What is the difference between Atlas and Atlas Gold:
Atlas Gold has shorter 21mm shoulders which minimizes vessel straightening and barotrauma (Atlas has 37mm shoulders)
b. Atlas Gold has enhanced tapered tip improving trackability
Does a 12mm conquest and a 12mm Atlas require a 8Fr sheath?
No, a 12mm Atlas can go through a 7Fr sheath. (and the 14mm Atlas does as well)
T/F: Glidewires should be twice the length of the device in use?
True
The most common cause of stenosis is?
intimal hyerplasia
What is Intimal hyperplasia?
Scar tissue forming in the lumen of the vessel due to trauma, increased flow (turbulent).
How many anastomoses does AV grafts have?
2; venous and arterial
How many anastomoses do AV fistula’s have?
1; arterial. AVF’s have a juxta anastomosis which is located 1-2cm before the arterial anastomosis.
