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.

A device and method is provided to gain access to interior body regions. The system includes a safety needle assembly, a blade assembly, an obturator assembly, and a dilator assembly. The safety needle assembly accesses an interior body region, after which the blade assembly expands the pathway created by the safety needle assembly. The obturator then further expands the pathway and delivers the dilator assembly to the desired location. The safety needle assembly, obturator assembly, and blade assembly are removed, leaving the dilator assembly in place for future procedures.
