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 to provide a cutting edge which is formed thereon. The device also includes means for preventing rotation of the stylet relative to the needle and means for releasably securing the stylet in a fully inserted position.
