Abstract:
1. A medical coil which is formed by winding an element wire, comprising: a plurality of loops formed by helically winding the element wire, the plurality of loops being disposed on a same axis, a convex part which is provided on a first end surface of each of the plurality of loops in an axial direction of the medical coil; and a concave part which is provided on a second end surface of each of the plurality of loops in the axial direction of the medical coil, wherein a line forming a connection between an upper most part of a top part of the convex part and a deepest part of the concave part forms a non-zero angle relative to a longitudinal axis of the medical coil in a natural state in which a compressive force is not applied in the axial direction, and the concave part has a slant face, and when the compressive force is applied in the axial direction of the medical coil, the top part of the convex part is configured to slide on the slant face of the concave part and to approach the deepest part.
