Scientists from Sungkyunkwan University and other institutes of South Korea have developed a new type of epicardial reservoir that has the potential to revolutionize the methods of diagnosing and treating heart diseases, including arrhythmia and myocardial infarction.
Unlike traditional epicardial plasters, which require surgical sewing to the heart and pose risks, this new invention has the ability to stretch and stick, eliminating the need for seams.
Professor Donhi Son, one of the leading researchers, explained, “The traditional attachment of epicardial plasters is a complex and time-consuming task. Long-term use leads to a deterioration in strength and the occurrence of an unwanted gap between the patch and heart tissue, which complicates diagnosis and treatment.”
The new patch is composed of three materials: liquid conducting composition, mesh, and ion adhesive. This combination eliminates the need for seams, making the procedure safer and more convenient for medical workers.
The main innovation of the patch is its use of jelly-like materials (hydrogels) with ion conductivity inspired by the adhesion of naval mussels. These hydrogels allow the patch to instantly attach to the heart without the need for seams.
Thanks to liquid metal electrodes, the new patch demonstrates high reliability and stability when monitoring heart signals. “We conducted experiments on the recording of heart signals on animals for four weeks, which was a significant breakthrough,” added Professor Son.
In addition to diagnosis, the patch can also intervene in abnormal signals, adjusting the rhythm of the heart and contributing to its normal operation. Its softness and adhesiveness ensure that it does not cause damage to tissues or inflammations.
Professor Song, another researcher involved in the study, concluded, “Our results emphasize the potential of this technology in the field of diagnosing and treating heart diseases. Our new development can open new opportunities for personalized medicine, allowing treatment to be adapted to the individual needs of each patient.”
