These are microcatheters.commonly used in embolization of intracranial Aneurysms
How to use micro-catheters
- When using a micro-catheter, a standard angiographic catheter that accepts a 0.038- or 0.035-inch guide
wire is
first placed securely in a proximal position in the blood vessel.
- The micro-catheter is then inserted through the outer catheter and advanced in conjunction with a specially
designed 0.010- to 0.025-inch guide wire through the standard catheter lumen.
- Once a superselective position has been attained with the micro-catheter, a variety of
procedures can be
performed, including embolization, sampling, or low volume angiography.
Guiding catheters
- Designed to make selective catheterization and interventions easier. These catheters can be used in some
situations to help position and stabilize standard catheters.
- These catheters can be used in some situations to help position and stabilize standard catheters.
- They are used in circumstances in which standard catheters are difficult to position selectively.
Guiding Catheter
These are large lumen catheters that are placed proximal to give stable position for placement of
instruments like
micro-catheters, coils, stents within target lesion.
Y Connector
These are connected on the hub of guiding catheters for hemostasis and for placement of micro-catheters as well as
allow a continuous infusion of heparinized saline from the side port.
