Medical Catheter Drug Coating Preparation
Medical Catheter Drug Coating Preparation – Cheersonic
The development of medical catheters has a history of 100 years. From the earliest Egyptians to use palm leaves to make urinary catheters to various balloon catheters now, the advancement of technology has brought more hope to our patients’ lives.
A catheter is a flexible hollow tube that fits inside a duct, cavity or blood vessel in the body. The tube body can be straight or formed into different curved shapes, and the head end can be tapered or non-tapered. An angiographic catheter is the most important tool in any vascular intervention. They are accessed through a sheath placed at the vascular access site. Access to the target vessel is guided by a guidewire within these catheters. Perform diagnostic angiography on predetermined vascular regions, and deliver balloons and stents for endovascular intervention as catheters at predetermined locations.
An excellent catheter should have good controllability, flexibility, non-invasive tip and good hydrophilicity to reduce surface friction, so as to have good traceability under the guidance of the guide wire.
Catheter Surface Coatings: Surface coatings can alter the coefficient of friction, prothrombotic, or antimicrobial properties of catheters. Outer layer: Angiographic catheters can be made of polyethylene, polyurethane, nylon, polytetrafluoroethylene, silicone, polyvinyl chloride, or combinations of these materials.
The drug balloon coating is prepared by the ultrasonic atomization spraying process, which not only ensures the uniform and controllable size of the coating crystal particles, but also makes the coating more dense, uniform and firm, reduces the loss of drugs during the balloon delivery process, and ensures a sufficient amount Drug delivery to the target lesion site.
