The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and/or manipulate the patch from a location outside of the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and/or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and/or positioning of the patch or plug over the opening or weakness.
