Abstract

Abstract A system for treating a vascular condition includes a conduit having an inner wall and at least one locking member positioned within the inner wall of the conduit. The system also includes a stented valve positioned in contact with the locking member within the inner wall of the conduit. A method for treating a vascular condition includes inserting a conduit with a stented valve into a target region of a vessel, positioning a contact portion of the stented valve against a locking portion of the conduit and preventing migration of the stented valve within the conduit based on the positioning.
