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 modalities.
