Abstract
An improved pneumoneedle wherein the stylet forms part of an assembly removably received within the needle housing. The assembly carries a valve to selectively open or close the needle to fluid flow. The stylet is slidably carried by the assembly and resiliently biased to extend through the needle. Removal of the assembly opens the needle. A septum is engagable with the housing to seal the needle when the assembly is removed. A viewable indicator carried by the stylet signals when the needle has completed penetration.
