ABSTRACT:
A cell or tissue retrieving instrument is slidably mounted within the needle of a conventional "Skinny Needle" and is connected to the needle syringe piston. In use, the needle with the instrument enclosed therein is inserted inwardly into the patient's organ. The instrument is held fixed and the needle is moved outwardly to expose the instrument within the organ. The instrument retrieves cell or tissue from the organ while being pulled into the needle and the needle with the enclosed instrument is removed from the patient.
A device is also disclosed for manipulating the "Skinny Needle" and tissue retrieving instrument in the method of performing the biopsy.
