This study evaluates the in vivo performance of the
magnetically assisted remote controlled (MARC) catheter
in a renal embolization model using MR image guidance.
The MARC catheter is navigated through the aorta and
into the origin of the renal artery at which point
embolic spheres (100 to 300 uM in size) are delivered
through the catheter into the kidney. The intervention
is repeated using X-ray guidance and performance
parameters are compared between the two imaging
