Abstract
An endoprosthesis assembly adapted to be securely positioned within a body lumen is provided with one or more hooks adapted to engage tissue that defines the body lumen. The endoprosthesis includes a resilient self-expanding anchor attached to the tubular graft. The anchor and hooks carried by the anchor are constructed to enable the endoprosthesis to be recaptured in a delivery device to enable repositioning or removal of the endoprosthesis and any time prior to complete deployment of the endoprosthesis in the patient.
