发明名称 Deployment system for myocardial cellular material
摘要 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).
