There is growing interest in delivering cellular agents to in-
farcted myocardium to prevent postinfarction left ventricular
remodeling. MRI can be effectively used to differentiate in-
farcted from healthy myocardium. MR-guided delivery of cellu-
lar agents/therapeutics is appealing because the therapeutics
can be precisely targeted to the desired location within the
infarct. In this study, a steerable intramyocardial injection cath-
eter that can be actively tracked under MRI was developed and
tested. The components of the catheter were arranged to form
a loopless RF antenna receiver coil that enabled active tracking.
