摘要:
A device and method is provided to gain access to interior body regions. The system includes a stylet needle assembly, a safety needle assembly, a blade assembly, a retractable 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.
