Intramyocardial injection. After myocardial infarction a hydrogel derived from multiple possible sources is injected into the superficial myocardial using multiple injections. The hydrogel can distribute beyond the infarct zone and into the border zone. The hydrogel can act as a bulking agent to restore myocardial structure or can deliver growth factors to targeted areas. This technique can be used in concomitance with revascularization.
