1. A needle injection catheter system for delivering cellular aggregations to a patient's heart, the needle injection catheter system comprising:
a source of cellular aggregations;
a catheter body having a distal end, a proximal end, and a delivery lumen therethrough, said delivery lumen configured to receive an injectable amount of cellular aggregations from the source of cellular aggregations; and
a helical needle extending from the distal end of the catheter body and having at least one helical delivery lumen connected to receive the injectable amount of cellular aggregations from the delivery lumen of the catheter body, wherein said helical delivery lumen has a bore size which is sufficiently large to deliver the injectable amount of cellular aggregations into heart tissue.
