New catheter design delivers 183x higher drug concentration
Micro 3D printing is revolutionising drug delivery, offering new possibilities for precision-targeted therapies. At City of Hope Cancer Center, researchers used Projection Micro Stereolithography (PµSL) to develop a barbed catheter inspired by bee stingers, capable of delivering high-dose medication directly into liver tumours.
Traditional methods failed to offer the required micron-level precision. The 3D-printed catheter maintained accurate positioning and enabled 183x higher local drug concentration than standard IV injection—highlighting its potential in personalised cancer treatments.
Micro 3D printing is now a critical enabler in cost-effective, patient-specific medical device production.
