Method and apparatus for recapture of hooked endoprosthesis

摘要

An endoprosthesis assembly 10 adapted to be securely positioned within a body lumen is provided with one or more hooks 24 adapted to engage tissue that defines the body lumen. The endoprosthesis includes a resilient self-expanding anchor 14 attached to the tubular graft. The anchor 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.
