Although in terms of the overall production and processing of medical guidewire, more enterprises produce the general standard type of guidewire. For example, many enterprises produce straight guidewire, but many enterprises also produce some special types of guidewire, such as J-shaped safety guidewire.

A J-shaped safety guide wire is a type of safety guide wire, so named because of the J-shaped bend in the front of the guide wire. Due to the relationship between structure and technology, this guide wire has the advantages of bending blood vessels during intubation, and the front end of the guide wire will not be pressed against the blood vessel wall, so as to prevent blood vessel damage. Therefore, it is relatively safe to use. Because of this, it has won the favor of users in some fields, which also makes many medical guide wire manufacturing enterprises start to produce this kind of guide wire.

Although production are J security thread, but on the medical guide wire production and processing is also there will be a lot of different requirements, because this kind of thread can further subdivided into several different types, such as from the godet front end bending degree, can be divided into large, medium and small, including small bending is suitable for the blood vessels, large bending can help to adjust the direction of intubation. In addition, J-shaped guide wire can be divided into fixed core, movable core and Teflon sheath from the perspective of structure.
