Pre-Lubricated Polypropylene Injector for Breast Implant Delivery

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