It is well known that guide wire plays a very important role in the diagnosis and treatment of cerebrovascular diseases. A good guide wire can make the operation more effective, and a poor guide wire can drive the surgeon crazy. The blood vessels in the brain are not only thin but also tortuous, and the requirements for the performance of the guide wire are higher. However, few domestic companies can do the necessary auxiliary equipment, and foreign companies are basically monopolized, especially the guide wire. The same is true for neurointervention. The microguide wire is also the most technically difficult, and the doctor uses the highest viscosity.

The basic concept of guide wire

Function: The guide wire has the function of introducing the catheter into blood vessels or other lumens of the body percutaneously, and is an important tool to assist the catheter to selectively enter small blood vessel branches or other diseased spaces, and to replace the catheter during operation.
Structure: soft tip (soft tip), connecting the tip and the middle section of the core rod and the proximal pushing rod section.
According to the latest classification of medical devices, micro guide wire is a kind of guide wire. Compared with the original 6877 classification catalog, the new catalog has added two examples of product names, guide wire and radiography guide wire.

Guide wire: The guide wire enters the coronary artery, and the balloon and stent can be used for intracoronary treatment along the guide wire. Contrast guide wire: The so-called super-smooth and non-super-smooth are not allowed to enter the coronary artery, and they are also called contrast guide wires. Their function is to guide the advancement of the contrast catheter, guide the contrast catheter to the coronary sinus, and the guide wire will be withdrawn. Out. Super-slippery and non-super-slippery are used in different ranges. Taking the radial artery as an example, super-slippery is used when the radial artery is flexed and the subclavian artery has a large turn. If you make a circle around the place, or if the push resistance is high, then you need to replace the ultra-smooth guide wire. This kind of guide wire has a hydrophilic coating on the surface, which is more “slippery”, but this kind of guide wire is soft and easy to enter the branch by mistake. The normal non-super slippery does not have this problem. Micro guide wire: Micro guide wire is used to insert into micro catheter to provide guidance and support for interventional diagnosis and treatment equipment. The head end is relatively soft, which is convenient for selective access to blood vessels; the tail end is relatively hard, which can play a good supporting role. At present, the diameter of the guide wire is used as the standard to distinguish between the guide wire and the micro guide wire. It is generally considered that the guide wire is less than 0.018in (the diameter of the commonly used micro guide wire is 0.010in and 0.014in).

The UAM7000 is a guide wire coating system designed to coat guide wire up to 300 mm in length. A rotating cassette fixture holds one catheter up to 2 meters in length.

The guide wire cassette assembly can be removed for coating other medical devices, making the UAM7000 a flexible R&D development system for a variety of medical device coatings.
