Abstract: An example catheter has an elongate member defining an elongate member proximal end, an elongate member distal end, an outer surface, and a main body, the outer surface defining a side opening at a position between the elongate member proximal end and the elongate member distal end, the main body defining a first lumen and a second lumen, the second lumen extending from the elongate member proximal end to the side opening; a balloon disposed on the elongate member between the side opening and the elongate member distal end; and an engagement member disposed in the second lumen, the engagement member defining an engagement member proximal end and an engagement member distal end, the engagement member proximal end extending axially beyond the elongate member proximal end, the engagement member distal end having an engagement portion and extending radially beyond the side opening in a first direction.

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.
