Abstract
The invention described herein relates to an improved device for paracentesis procedures, such as thoracentesis. The device comprises a cannula assembly, valve assembly, and catheter assembly, wherein the cannula assembly is removably attached to the valve assembly, and the valve assembly is removably attached to the catheter assembly. The device can comprise an externally viewable indicator revealing the relative positions of the cannula assembly components. The device can further comprise a locking mechanism which controls the movement between cannula assembly components and is activated and deactivated by the coupling of the cannula assembly to the valve assembly. The device improves the precision and safety of its handling, and offers the practitioner several aspiration alternatives while maintaining separation of the internal and external patient environments.
