Abstract

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.
