Abstract: A portal saver device for installing a flexible cannulated tube at a surgical site. A portal saver device includes an obturator. The obturator has an obturator body having a cannulated outer obturator tube extending therethrough. The outer obturator tube has a distal tip with a dilating assembly movable between a collapsed, first configuration and an expanded, second configuration. A shaft expander has a cannulated inner obturator tube, which is movable between a first position and a second position within the outer obturator tube. In the first position, the inner obturator tube is retracted from the distal tip of the outer obturator tube and the dilating assembly is in the first configuration. In the second position, the inner obturator tube is advanced within the distal tip of the outer obturator tube and the dilating assembly is in the second configuration.
