ABSTRACT:
A method and apparatus for removing fluid from the body of a patient, such as in paracentesis and thoracentesis, is provided. Fluid may be withdrawn via a needle assembly including a sharp introducing needle and a retractile blunt needle. The needle assembly may be withdrawn after the introduction of a drainage catheter, and a valve with multiple sealing points prevents body fluids from leaking from the device through the needle space and prevents communication between the atmosphere and the patient through the needle space. A second drainage port may be used after the needle is withdrawn.
