A prosthesis fixation system includes a delivery device having a distal end and a proximal end. The delivery device includes an inner cannula extending between the distal end and the proximal end of the delivery device, a positioner disposed coaxially over a first portion of the inner cannula, and a tip assembly attached to a proximal end of the inner cannula. A prosthesis is releasably coupled to the delivery device at the proximal end of the delivery device. At least one trigger wire extends longitudinally within a lumen of the positioner and at least one suture loop is attached to the proximal end of the positioner. A proximal end of the trigger wire extends proximally beyond the proximal end of the positioner such that trigger wire passes through the at least one suture loop and is removably attached to an end of the prosthesis.
