Abstract
An endoscopic needle assembly has an inner tube formed from a close-wound coil of wire surrounded by a sheath, an outer tube surrounding the inner tube such that the inner tube can move longitudinally relative to the outer tube, a needle joined to a distal end of the inner tube, and a two piece handle having a first handle piece attaching to the inner tube and a second handle piece attaching to the outer tube. A safety shield, formed from a plurality of hinged petals, is built onto the distal end of the outer tube to protect an endoscope from inadvertent penetration by the needle.
