The development of specialized delivery systems, such as the EndoWings® catheter described by Wang et al. (2024), is critical for the successful application of novel biomaterials like alginate hydrogels in complex biological environments. This research highlights how co-designing the delivery mechanism with the therapeutic agent can overcome significant translational barriers, enabling precise and safe administration of treatments directly to target tissues, such as the myocardium.
