3D printing custom catheters or will trigger the medical revolution

3D printing technology is applied in the field of medical devices. It can directly generate organ structures and print out stereoscopic models. Doctors can judge and implement complex operations based on this. The patient's heart surgery is very complicated, and the doctor needs to select the appropriate type of medical consumables as needed. Before the operation, the patient's heart model is printed, the doctor can make a more accurate judgment on the patient's heart structure, research and select the PDA occluder to be placed, and the skillful technology can greatly improve the treatment success rate. A lot of surgery that was impossible is possible.

Researchers at Northeastern University have developed a new approach to custom-made catheters for 3D printing of premature babies or other important medical devices.

According to reports, this 3D printing technology uses a composite of plastic and ceramic, and uses magnetic fields to help shape the anesthetic products. The printed ureteral catheters and other urology devices are stronger and lighter than traditional similar products, and can be tailored to help patients recover.

The most unique and revolutionary part of the 3D printing technology, the researchers say, is the ability to precisely arrange ceramic fibers using magnets to achieve overall control over the mechanical properties of the material. This fine control of the distribution of ceramic fibers offers great advantages: each corner, curve and material hole is able to achieve its precise medical function fully and permanently. By precisely controlling tiny ceramic fibers, medical staff can ensure that materials are as light and non-invasive as possible while ensuring their durability.

This ceramic fiber material is manipulated by magnets and iron oxide. The researchers initially magnetized these ceramic fibers by applying mild iron oxide. This process has long been approved by the FDA for medical purposes.
