Beschreibung
Zusammenfassung:	A medical device (50) suitable for introducing a medical instrument into a patient includes an outer cannula (52) and at least one arm (54) connected to the cannula toward a proximal portion of the at least one arm. The at least one arm (54) is deployable between a closed position and an open position. An inner member (82) is telescopically received in the outer cannula to hold each arm in the closed position. The inner member is deployable to disengage from the arm after the device is inserted into a patient, thereby freeing the arm (54) to be deployed to the open position where it helps hold the outer cannula in the patient. The inner member includes an inner cannula and/or a trocar (84).
