Abstract: Medical devices for repairing defects in tissue, such as perforations in the tympanic membrane of an animal, methods of manufacturing medical devices, methods of implanting a medical device in a defect in a tissue; and methods of repairing a defect in a tissue are described. In one form, a medical device includes an overlay member having multiple arms and defining an overlay member passageway, an underlay member having multiple flaps and defining an underlay member passageway, and a securement member extending through the overlay member passageway and the underlay member passageway. In methods, the multiple flaps of the underlay member can be sequentially advanced into a defect in a tissue, such as a perforation in a tympanic membrane of an animal.

Abstract: Medical devices for repairing perforations in tissue, such as the tissue forming the tympanic membrane, methods of manufacturing medical devices, and methods of implanting a medical device are described. An example method of manufacturing a medical device includes obtaining a first piece of material, obtaining a second piece of material, obtaining a divider defining an passageway that extends through the divider, positioning the divider between the first piece of material and the second piece of material such that the divider contacts the first piece of material and the second piece of material, attaching a portion of the first piece of material to a portion of the second piece of material within the passageway defined by the divider, and removing the divider from between the first piece of material and the second piece of material.
