摘要

The present invention provides a tubular therapeutic device indwelling device capable of suppressing the occurrence of damage to blood vessels and the like and the release of mural thrombus / mural atheroma. A tubular treatment device placement device (1) for placing a radially expandable stent graft (SG) in an affected area, the tubular treatment device placement device (1) comprising a tubular sheath (10). A rod member (30) configured to be able to advance and retract along the axial direction of the sheath (10) inside the sheath (10), and disposed at a distal end portion of the rod member (30) and provided on the stent graft (SG). And a tip (40) having an engaged portion (42) engageable with the hook (H). In the indwelling device (1) of the present invention, the engaged portion (42) is hidden in the sheath (10) when the distal end of the sheath (10) is sealed with the distal tip (40). It is characterized by being formed. [Selection] Figure 1
