Abstract
A stent supply instrument includes: a plurality of loops formed by spirally winding a wire or a strand wire made of a resin; joint portions that joint the loops to each other along a common center line; and a deformation holding section that holds a deformed shape of a stent detained in a coelom while holding the jointed state of the loops so that a projection area of the loops after deformation projected onto a virtual plane perpendicular to the center axis is smaller than the projection area of the loops before deformation projected onto the virtual plane. Here, the stent is released from the deformation holding section by means of a relative movement between the deformation holding section and the stent.

A stent supply instrument comprising:
- a plurality of loops formed by spirally winding a wire or a strand wire made of a resin;
- joint portions that joint the loops to each other along a common center line;
- and
- a deformation holding section that holds a deformed shape of a stent detained in a coelom while holding the jointed state of the loops so that a projection area of the loops after deformation projected onto a virtual plane perpendicular to the center axis is smaller than the projection area of the loops before deformation projected onto the virtual plane,
- wherein the stent is released from the deformation holding section by means of a relative movement between the deformation holding section and the stent.
