Abstract: A biopsy needle assembly and kit for acquiring a sample of tissue and method of using the same. The biopsy needle assembly includes a needle having a lumen extending therethrough and a stylet sized to extend through the lumen. A divided ergonomically shaped handle has a distal part formed around the proximal end of the needle and a proximal part formed around the proximal end of the stylet. These parts can be locked together, but only from a single right angle initial orientation with a rotation in one direction only from there to lock the two parts together. A stop ensures locked alignment. Locking the handle parts in alignment provides a known orientation between the distal ends of the needle and stylet. A Luer connector attached to the proximal end of the distal handle part is exposed only when the handle parts are disconnected for connecting either a plug or aspiration apparatus.

Abstract: A biopsy needle assembly and kit for acquiring a sample of tissue and method of using the same. The biopsy needle assembly includes a needle having a lumen extending therethrough terminating at its proximal end with a handle having a bore therethrough connected to said end. The proximal end of the bore of the handle includes a conical tapered section which increases in diameter from a point distal of the proximal end of the handle to the proximal end of the handle for sealably receiving an aspirator bulb. The aspirator bulb is utilized to aid in acquiring a tissue sample and retaining it within the lumen of the needle during removal of the biopsy needle assembly. An elastomeric plug can also be utilized to assist in retaining a sample. The biopsy needle assembly also includes a stylet sized for disposition within the lumen of the needle and extending beyond the distal end of the needle having a cutting edge formed on its distal end. The cutting edge can be spoon shaped, i.e.
