An expandable blood vessel graft (40) facilitates the rapid and secure insertion of the graft in a blood vessel (50). The graft includes a first radially pre-expand ed portion (41) and a second portion (42). The first portion (41) is connected to the second portion (42). The second portion has a diameter less than the diameter of the first pre- expanded portion. A system for use in a blood vessel, including the above mentioned graft and an expansion element (44), a method for inserting such a graft into a blood vessel, and a process for forming such a graft are also described. |
