- Medical Laser Processing Applications
Common laser processing of medical catheters include the following:
Laser cutting: Laser cutting is a common pipe processing method. The high energy density of the laser beam enables precise cutting of the catheter material. Laser cutting can be used to make different parts of the catheter, such as the end of the catheter, connectors, etc.
Laser welding: Laser welding is a processing method that uses the heat energy of a laser beam to weld different parts of the conduit. Laser welding can achieve a sealed connection of the conduit, ensuring the integrity and reliability of the conduit.
Laser drilling: Laser drilling is a processing method that uses the high energy density of the laser beam to form holes in the catheter. Laser drilling can be used for drainage holes, ventilation holes and other parts of the catheter to achieve specific functions of the catheter.
Laser etching: Laser etching is a processing method that uses the high energy density of the laser beam to etch on the surface of the catheter. Laser etching can be used to form specific patterns, markings or scales on the surface of the catheter to facilitate physician operation and observation.
Laser marking: Laser marking is a processing method that uses a laser beam to mark the surface of the catheter. Laser marking can be used to mark product information, serial numbers, brands, etc. on the catheter for easy tracking and identification.
Outer diameter reduction—laser ablation removes material from the exterior of the catheter in sub-micron-thick layers, one layer at a time. This technique works well at both macro and micro scales for a wide variety of medical products, including neurovascular, cardiovascular, and other minimally invasive products.
Laser-cut features—lasers remove material to create access ports in tubing (for example, fenestrated IV catheters) or to selectively expose functional parts. Lasers drill through one layer of the catheter structure at a time to create micro holes or other geometric shapes to specific depths. Laser cutting is preferred for tiny features in infusion catheters, balloon catheters, and embolic protection filters.
Surface finish—lasers are used to create high-precision, micro-sized features or patterns on catheter surfaces to enhance performance and functionality. A rougher surface can be beneficial when bonding or welding parts together because it increases bond strength. A textured or patterned surface can also help manage surface tension when moving components are in contact or slide along the same plane or surface.
These laser processing methods can be selected and applied based on the material, design requirements and functional needs of the catheter. Laser processing has the advantages of high precision, no contact, and no pollution, and can achieve precise processing and customization of catheters. The specific laser processing methods and parameters should be determined according to the specific requirements of the catheter and the production equipment.
