ABSTRACT:
Apparatus and methods for performing fine-needle aspiration biopsies are disclosed. Each method and apparatus includes a needle having an opening which can be occluded during both the penetration and withdrawal stages of the aspiration cycle. After penetration of the target area, the needle is reciprocated a predetermined number of times determined by the desired cytological sample yield. The needle is unoccluded during the reciprocation phase of the cycle. Both manual and automatic apparatus for performing the fine-needle aspiration biopsy procedures in accordance with the disclosed method are disclosed. Numerous sheath configurations for various biopsy applications are illustrated, including those applicable to prostate and breast or other soft tissue biopsies and for use in conjunction with ultrasonic transducers. Alternative needle configurations are disclosed to improve sample yield, reduce coring and minimize needle fouling.
