Pre-Lubricated Polypropylene Injector for Breast Implant Delivery

Abstract Breast augmentation is a common esthetic surgery, and there are two major surgical methods for breast implant delivery: the finger method and the plastic film method. Each method has its advantages and disadvantages, and we have developed a prelubricated polypropylene (PP) injector that might be the most suitable device for delivering breast implants. By covering the interior surface of the injector with a hydrophilic coating, the friction coefficient was significantly reduced when a silicone sled was slid against the prelubricated PP injector. To confirm if the prelubricated PP injector would not damage the breast implant, fatigue testing was performed, and the results showed that the injector did not cause rupture or microleakage of the breast implant. In addition, the cell viability result demonstrated that the prelubricated PP injector was biocompatible. In addition, the prelubricated PP injector provides a small incision site and stability during breast implant delivery. Our results provided evidence that the prelubricated PP injector is a smooth and safe method for breast implant delivery.
