摘要：
A surgical access assembly for positioning within an opening in a tissue to provide access to a patient's body for insertion of surgical instrumentation therethrough. The surgical access assembly includes a body portion defining a longitudinal axis and a passageway and having a proximal portion and a distal portion. At least a portion of the distal portion is configured to transition from a more flexible, first configuration for passage into a patient's body and a more rigid, second configuration to securely maintain the distal portion within the patient's body.
