Catheter

1. A catheter comprising:

a catheter shaft including:

a body portion, and

a bend that extends distally from a distal end of the body portion, wherein:

a braid is embedded in the catheter shaft, the braid having a first wire and a second wire woven together, the first wire having a high tensile strength and the second wire having a low tensile strength that is lower than the high tensile strength of the first wire, and

when viewed from a proximal end of the catheter shaft, the bend forms an arc that extends in a nonlinear winding direction of the first wire.

2. The catheter according to claim 1 , wherein the bend includes:

a first tilted portion that extends obliquely relative to the body portion through a first bend that is bent in a first direction, and

a second tilted portion that is tilted relative to the first tilted portion and extends distally through a second bend that is bent in a second direction, the second direction being a direction that is different from the first direction.

3. The catheter according to claim 2 , wherein the second bend is bent at an acute angle with respect to the first tilted portion, which is lesser than an angle at which the first bend is bent relative to the body portion.

4. The catheter according to claim 1 , wherein when viewed from the proximal end of the catheter shaft, the bend forms an arc that extends along a circumference of a circle.

5. The catheter according to claim 1 , wherein when viewed from the proximal end of the catheter shaft, the bend forms an arc that extends along a circumference of an ellipse.

6. The catheter according to claim 1 , wherein the first wire has a thickness that is greater than a thickness of the second wire.
