Microcatheter Device Composition
Microcatheter Device Composition – Ultrasonic Coating Catheter – Cheersonic
A microcatheter is generally composed of a handle (seat), a strain relief sleeve, a tube body, and an indicator. The design and manufacture of the tube body play a key role in the performance of the microcatheter, and the microcatheter body usually includes an inner liner, a middle reinforcing layer, an outer polymer, a surface coating, and the like.
Among them, the lining material is usually selected lubricating material (such as PTFE) to ensure a smooth lumen.
The middle reinforcing layer usually uses metal wire braiding or winding to achieve the design method of increasing catheter strength and pushing force. Among many microcatheters, this braiding or winding method can be roughly divided into: braiding, winding, braiding + winding ( Parallel), braid over wrapping (multi-layer) 4 types, the design of the middle reinforcement layer represents the important performance requirements of different vascular lesions for microcatheters, such as the design of braiding + wrapping can make the braiding at the proximal end more pushable, and the winding at the distal end is soft Good resistance, which is a very good choice for neurovascular transport, and for CTO lesions, high stiffness braiding can help it cross calcification.
The polymer material of the outer layer is also in line with the actual clinical use. A series of materials with different hardness are used to conduct mechanical transmission from near to far. This idea of gradual change in hardness actually coincides with the design of the middle layer; , the distal surface of the tube body is usually coated with a certain length of coating material (usually a hydrophilic coating) to improve the passage of the microcatheter in blood vessels and lesions.
It is this “sandwich” structure design of lining + middle layer + outer layer + surface coating that creates the excellent performance of the microcatheter “opening roads when encountering mountains and building bridges when encountering water”.
UMC7100 Ultrasonic Balloon Catheter Coating Machine is designed for drug eluting balloons. It provides a uniform drug coating for the balloon catheter through ultrasonic spray technology. UMC7100 can also be used to adjust and control the deposition process of drug coatings for different liquid formulations. With the help of a special fixing device design, the entire balloon catheter can be sprayed with a maximum spraying length of 280 mm., It also has the functions of solvent doping, pre-heating, humidity control, and drying. The equipment has the characteristics of precise application amount, uniform film layer, and high utilization rate of chemical liquid. Cheersonic has extensive experience in surface coating of implantable medical devices (such as drug stents and balloons), and can provide customers with complete solutions.
