an inner resin layer arranged on an inner surface of the hollow coil, the inner resin layer defining a lumen, and
an outer resin layer arranged on an outer surface of the hollow coil;
a tip made of resin that is provided at a distal end of the catheter body, the tip having a tapered section with an outer diameter that continuously decreases from the distal end of the catheter body to a distal end of the tip, the tip having an inner bore communicating with the lumen of the inner resin layer, wherein the inner resin layer is made of at least two different layers and the tip is made of a material that is softer than a material of the at least two different layers; and
a braid extending in an axial direction of the catheter body across a boundary between a proximal end of the tip and the distal end of the catheter body, the braid also extending into the tapered section of the tip and being positioned between the inner resin layer and the hollow coil in the catheter body, wherein
the hollow coil does not extend across the boundary.
a second coil extending from the boundary toward the distal end of the tip, wherein a distance between a distal end of the second coil and the boundary is shorter than a distance between a distal end of the braid and the boundary.
3. The catheter according to claim 2, wherein the tapered section of the tip does not contain the second coil.
4. The catheter according to claim 1, wherein a distal end of the braid is distant from the distal end of the tip.
a tip made of resin that is provided at a distal end of the catheter body, the tip having: i) a tapered section with an outer diameter that decreases toward a distal end of the tip, and ii) an inner bore communicating with the lumen of the inner resin layer; and
a braid extending in an axial direction of the catheter body across a boundary between a proximal end of the tip and the distal end of the catheter body, wherein
the hollow coil does not extend across the boundary,
the inner resin layer includes an innermost layer and a middle layer that is positioned between the innermost layer and the hollow coil,
a distal end of the innermost layer: i) extends across the boundary toward the distal end of the tip, and ii) is closer to the distal end of the tip than is a distal end of the middle layer,
the braid is embedded within the middle layer in the catheter body, and
a distal portion of the braid projects from the distal end of the middle layer toward the distal end of the tip, so that the distal portion of the braid is embedded within the tapered section tip.
7. The catheter according to claim 6, wherein a portion of the tip does not contain the second coil.
8. The catheter according to claim 5, wherein a distal end of the braid is distant from the distal end of the tip.
9. The catheter according to claim 5, wherein the tip is made of a material that is softer than a material of the innermost layer and a material of the middle layer.
