Properties
-
have multiple side holes placed typically on the shaft, behind the tip2
allows large-volume infusions and prevents vascular injury at the tip of the catheter during power injections
uniform dispersal of contrast media
minimal recoil
-
tip-shape designed to
help center the shaft in the vessel
avoid engagement and injection into a non-target vessel
-
blunt leading contours
to advance without a leading guidewire
high wall strength
low friction coefficient
Indication
-
aortic angiography
-
superior vena cava phlebogram
