Catheters

100

For what purpose do some catheters deliver radiopaque media?

Possible answers:

• To increase pushability to get through tough lesions

• For diagnostic support

• To place an additional catheter through the initial catheter, for extended reach

• To smooth tracking through vasculature

• Allow directionality for vessel selection and lesion access

For diagnostic support

Eg. Show arteries on fluoroscope
