Outline of Final Research Achievements |
The purpose of this study is to develop new myocardial biopsy forceps that can safely collect heart tissue and to confirm their usefulness. In 2020, we evaluated the conditions for detecting contact with the myocardial tissue using commercially available forceps through animal experiments and created a prototype equipped with a passive electrode. In 2021, we devised a contact pressure detection function using optical fibers and confirmed its effectiveness through in vitro and animal experiments. In 2022 and 2023, we focused on miniaturizing this function and combining it with a cell collection feature, as well as developing a safe driving mechanism for the forceps.
