ABSTRACT:
A safety penetrating instrument for penetrating an anatomical cavity wall to gain access to an anatomical cavity includes a cannula having a distal end for introduction in the anatomical cavity, a penetrating member disposed in the cannula and having a distal end for penetrating the anatomical cavity wall protection means for placing the safety penetrating instrument in a protected state where the penetrating member distal end is protected and not exposed and trigger means proximally movable during penetration of the anatomical cavity wall for triggering the protection means to place the safety penetrating instrument in the protected state upon the trigger means moving a predetermined proximal distance. Where the predetermined proximal distance corresponds to the thickness of the anatomical cavity wall, the safety penetrating instrument will be placed in the protected state upon introduction of the cannula distal end in the anatomical cavity. A method of forming a portal in an anatomical cavity wall includes the steps of penetrating the anatomical cavity wall with a safety penetrating instrument and triggering the safety penetrating instrument to move to a protected state where a penetrating member of the safety penetrating instrument is protected upon movement of a trigger member of the safety penetrating instrument a predetermined proximal distance corresponding to the thickness of the anatomical cavity wall.
