Abstract
A dissolvable repair device, and a method utilizing the same, that is intended to aid in the repair and healing of a perforation in body tissue, such as a nasal septum. The repair device is intended to be placed over the area of the perforation to act as a scaffolding for the regrowth of tissue over the perforation. The repair device is made from a bioerodable material that is dissolvable upon exposure to certain fluids, including body fluids. Over time, the repair device will dissolve, allowing sufficient time for tissue to regrow over the area of the perforation. Since the repair device is dissolvable, a surgical procedure is not required in order to remove the repair device.
