Braided flange branch graft for branch vessel

A delivery system comprising:

• a braided flange branch graft formed from a braided super elastic memory material, said braided flange branch graft having a delivery configuration and a deployed configuration, said braided flange branch graft comprising:
• a first flange having a substantially saucer shape in the deployed configuration and a substantially cylindrical shape in the delivery configuration;
• a second flange having a substantially saucer shape in the deployed configuration and a substantially cylindrical shape in the delivery configuration;
• a neck between said first flange and said second flange;
• and
• a trunk extending longitudinally from said second flange, said trunk having a substantially cylindrical shape in the deployed configuration and a substantially cylindrical shape with a reduced diameter and an increased length relative to the deployed configuration in the delivery configuration;
• a handle;
• an inner member extending distally from said handle, said braided flange branch graft being located over a distal portion of said inner member;
• a neck hook connected to said neck of said braided flange branch graft;
• an inner end hook connected to an inner end of said braided flange branch graft, said inner end hook being longitudinally translatable relative to said neck hook, wherein longitudinal translation of said inner end hook away from said neck hook stretches said first flange into the delivery configuration and wherein longitudinal translation of said inner end hook towards said neck hook converts said first flange from the delivery configuration to the deployed configuration;
• and
• a base hook connected to a base of said trunk, said base hook being longitudinally translatable relative to said neck hook, wherein longitudinal translation of said base hook away from said neck hook stretches said second flange into the delivery configuration and wherein longitudinal translation of said base hook towards said neck hook converts said second flange from the delivery configuration to the deployed configuration.
