A 5 prosthetic conduit system as described includes: an expandable main conduit having a first open end, a second open end, a main conduit wall extending therebetween, at least one opening through the main conduit wall, and an internal channel having an inner surface, an outer surface, a first open end located within the main conduit, and a second open end at the opening in the 10 main conduit wall an expandable secondary conduit extending through the internal channel and outwardly through the opening in the main conduit wall, the secondary conduit having a longitudinal axis extending between a first open end and a second open end of the secondary conduit, the secondary conduit having a secondary conduit wall extending between the first open end and the is second open end of the secondary conduit, and an attachment portion extending outwardly from the main conduit wall at an angle of less than 90 degrees relative to the secondary conduit axis when in a deployed state and engaging a portion of the internal channel to constrain axial displacement of the secondary conduit relative to the main conduit. 20 4111574_1 (GHMatters) P83106.AU.1 26/02/13
