摘要：
The present invention discloses a steerable guidewire and a method for manufacturing the same, and a steerable catheter and a method for manufacturing the same. According to an aspect of the present invention, a steerable guidewire, which is inserted into a catheter and guides the catheter to a desired blood vessel, may include: a steerable tip part that can be bent in at least two stages due to a stimulus from the outside and that is steered in a predetermined direction； and a non-steerable tip part that is not steerable. The steerable tip part may include: a first steerable tip part having a first length and bent in a first angle with respect to the non-steerable tip part； and a second steerable tip part having one end connected to the first steerable tip part, having a second length, and bent and steered into a second angle with respect to the non-steerable tip part. The first steerable tip part may be positioned farther from the non-steerable tip part than the second steerable tip part. The first length of the first steerable tip part may be smaller than a sum of lengths of steerable tip parts other than the first steerable tip part, and the first angle may be steered so as to be larger than the second angle.
