Medical material

A medical material comprising a tubular body having a mesh structure formed of a bioabsorbable linear material and including a substantially middle portion and two tubular portions, the two tubular portions including a first tubular portion and a second tubular portion between which the substantially middle portion is provided;

• wherein
• the substantially middle portion is smaller in tube diameter than other portions;
• the first tubular portion with a first end and the second tubular portion with a second end 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 is substantially in a shape of a hollow cylinder, the distal connecting part is substantially in a shape of a cylinder, the proximal connecting part and the distal connecting part are configured such that the cylinder of the distal connecting part is insertable into the hollow cylinder of the proximal connecting part, and 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;
• an inner diameter of the proximal connecting part is larger than an outer diameter of a delivery cable to be inserted into the catheter;
• the distal connecting part is configured to selectively achieve 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 extend through the substantially middle portion, be inserted into the hollow cylinder of the proximal connecting part, and extend out of the medical material in a direction from the second end to the first end;
• the distal connecting part includes:
• a radially outer portion larger than an outer diameter of the delivery cable and smaller than the inner diameter of the proximal connecting part;
• and
• an engaging portion larger than an outer diameter of the radially outer portion;
• the proximal connecting part includes:
• a radially inner portion which fits the radially outer portion;
• and
• an engaged portion which is larger than an inner diameter of the radially inner portion and which fits the engaging portion;
• and
• 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 a transition from the unlocked state to the locked state.
