Patent attributes
Methods and devices are provided for accessing a surgical site. In one embodiment, an access device is provided having a housing and a cannula extending distally therefrom. The cannula and the housing can define a working channel extending longitudinally therethrough. The cannula can be movable between an insertion configuration and a deployed configuration. The access device can also include an obturator insertable through the working channel. In one embodiment, the obturator can be configured to selectively mate with the cannula such that rotation of the obturator is effective to cause corresponding rotation of the cannula. In another embodiment, the obturator can be configured to move the cannula from the insertion configuration to the deployed configuration when the obturator is fully disposed within the cannula.
