Abstract
A medical material makes it possible to perform less invasive treatment of atrial septal defect and is unlikely to cause problems in the late post-treatment period. A medical material includes a substantially middle portion and two tubular portions (first tubular portion, second tubular portion) having a mesh structure formed of a bioabsorbable linear material and includes a proximal connecting part connected to a first end and a distal connecting part connected to a second end and threaded to a delivery cable. The proximal connecting part and the distal connecting part are configured to reversibly or irreversibly achieve a locked state and an unlocked state, the locked state being a state in which the proximal connecting part and the distal connecting part remain united, the unlocked state being a state in which the proximal connecting part and the distal connecting part do not remain united. When the distal connecting part is inserted into the proximal connecting part, the engaging portion of the distal connecting part engages with the engaged portion of the proximal connecting part to cause the medical material to transition from the unlocked state to the locked state.
