Adhesive material injection device

A medical instrument comprising:

• an adhesive material injection device, the adhesive material injection device including a tubular member including a first lumen extending between a first distal opening and a first proximal opening of the tubular member and a second lumen extending between a second distal opening and a second proximal opening of the tubular member at a position different from the first lumen, the first distal opening being located on a distal side relative to the second distal opening in a longitudinal direction of the tubular member, and an adhesive material configured to be held in the first lumen between the first distal opening and the first proximal opening, and wherein the tubular member includes a hub portion between the first proximal opening and the second proximal opening;
• an introduction sheath having a lumen into which the adhesive material injection device is configured to be inserted, the introduction sheath includes a sheath hub portion connectable to the hub portion;
• and
• the adhesive material injection device is implemented such that the first proximal opening of the adhesive material injection device is located on the distal side relative to the introduction sheath in a state where the hub portion is connected to the sheath hub portion.

An adhesive material injection device comprising:

• a tubular member including a first lumen extending between a first distal opening and a first proximal opening of the tubular member and a second lumen extending between a second distal opening and a second proximal opening of the tubular member at a position different from the first lumen, the tubular member includes a first region and a second region, the second region being located on a proximal side relative to the first region, and the second lumen is longer than the first lumen and extends over the first region and the second region;
• the first distal opening is located on a distal side relative to the second distal opening in a longitudinal direction of the tubular member, the first proximal opening is located between the second distal opening and the second proximal opening, and a cross-sectional area of the second lumen is smaller than a cross-sectional area of the first lumen in the first region;
• and
• wherein the first lumen is configured to hold an adhesive material between the first distal opening and the first proximal opening.
