Hollow fibers made of biocompatible polycaprolactone can “absorb” liquid medications such as antibiotics, painkillers, and insulin. Depending on the heat sensitivity of the medication, it can be incorporated into the fiber during manufacturing or processing.
Once implanted, the drug is released through the porous walls of the fiber. This mechanism can be tuned by changing the fiber thickness and other properties. Antibiotic-loaded sutures for wound healing are expected to be the first to be used.
