1. A medical material comprised of a tubular body that has a mesh structure formed of a bioabsorbable linear material, wherein:
the medical material has a shape in which a substantially middle portion of the tubular body is smaller in tube diameter than other portions of the tubular body;
the medical material has a first tubular portion with a first end and a second tubular portion with a second end which are arranged with the substantially middle portion therebetween, the first end and the second end being opposite ends in a longitudinal direction of the tubular body;
when the medical material is contained in a catheter such that the first end and the second end are away from each other with the substantially middle portion therebetween and that the other portions have a reduced tube diameter, the second end is located on the same side of the catheter as a distal end of the catheter;
the medical material includes:
a proximal connecting part connected to the mesh structure at the first end; and
a distal connecting part connected to the mesh structure at the second end;
the proximal connecting part and the distal connecting part each have a hollow tubular shape, and are capable of selectively achieving: a locked state in which the proximal connecting part and the distal connecting part remain united; and an unlocked state in which the proximal connecting part and the distal connecting part do not remain united;
an inner diameter of the proximal connecting part is larger than an outer diameter of a delivery cable inserted in the catheter;
the distal connecting part is capable of selectively achieving a connected state in which the distal connecting part is connected to a distal end of the delivery cable and a disconnected state in which the distal connecting part is not connected to the distal end of the delivery cable;
the medical material is configured to allow the delivery cable, which has the distal end thereof connected to the distal connecting part, to pass through the substantially middle portion, be inserted into a hollow tube of the proximal connecting part, and pass out of the medical material in a direction from the second end to the first end,
the proximal connecting part and the distal connecting part each have a hollow cylindrical shape;
an outer diameter of the distal connecting part is smaller than the inner diameter of the proximal connecting part;
the distal connecting part has a recess in an outer peripheral surface thereof;
the proximal connecting part has, on an inner peripheral surface thereof, a protrusion configured to engage with the recess;
the delivery cable is configured such that the delivery cable is rotated in a first direction to allow the recess and the protrusion to engage with each other and, even when the delivery cable is rotated in a second direction opposite to the first direction, the locked state in which the proximal connecting part and the distal connecting part are united is achieved;
the distal connecting part is a hollow tubular object having an internal thread;
the delivery cable has, at the distal end thereof, an external thread configured to be screwed into the internal thread;
the connected state is achieved by screwing the external thread into the internal thread by rotating the delivery cable in the first direction, and the disconnected state is achieved by unscrewing the external thread from the internal thread by rotating the delivery cable in the second direction; and
the medical material is configured such that the external thread and the internal thread are capable of being unscrewed from each other while the proximal connecting part and the distal connecting part remain united and locked.
