AI Technical Summary
Existing medical devices used for shunt treatment in heart failure patients face challenges in accurately applying energy to the target site due to potential positional displacement between the expansion body and the biological tissue during the enlargement of the shunt hole.
A medical device is designed with an expansion body that includes a hold portion capable of being opened and closed in the holding direction, which holds the biological tissue from both sides, thereby suppressing positional displacement and ensuring accurate energy application.
The device effectively suppresses positional displacement of the expansion body, ensuring accurate and consistent application of energy to the target site, thereby enhancing the therapeutic effectiveness of the shunt treatment.
