A medical device including a mesh prosthesis having a first mesh layer affixed to a second mesh layer along a perimeter area. An enclosure is defined between the first and second layers and extends inwardly from the perimeter area. An opening in the first layer passes through the first layer to the enclosure. A fixation guide template defines a guide pocket within the enclosure. A resilient deployment structure is removably disposed within the enclosure and extending toward the perimeter area. The resilient deployment structure has an elasticity that generates a resilient deployment force for urging the mesh prosthesis to a deployed configuration from a non-deployed configuration. A shield projection extends outwardly from a perimeter of the resilient deployment structure and is engaged within the guide pocket to prevent relative rotational movement between the resilient deployment structure and the mesh prosthesis. A method of using a medical device is also included.
