Abstract
Abstract A catheter-based deployment system for deploying cellular material ( 22 ) into the heart muscle ( 25 ). The deployment system includes a guiding catheter ( 19 ) and a needle assembly ( 31 ) capable of sliding within the guiding catheter. The needle assembly ( 31 ) terminates in a tip ( 34 ) having at least one side with an opening ( 43 ) in communication with a lumen ( 20 ) disposed within the needle assembly ( 31 ). Once the guiding catheter ( 19 ) is positioned the needle assembly ( 31 ) is advanced until the tip ( 34 ) penetrates the muscle wall ( 25 ). At a predetermined depth the cellular material ( 22 ) may be deployed into the muscle wall ( 25 ) via a push rod ( 46 ) disposed through the lumen of the needle assembly ( 31 ).
