Prepackaged collections of the devices and supplies (either custom or standard) needed for performing an aspiration biopsy under ultrasonic guidance. Items in these kits usually include a cup, gauze, lidocaine, needles, syringes, specimen tube with cap, a scalpel, and towels; kits may also include a coaxial needle, a biopsy gun, a wrap, and a sterilization pouch. The kits are frequently supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Ultrasound aspiration biopsy procedure kits and trays are used during the removal of living tissue using ultrasonic guidance for microscopic (in-vitro) laboratory examination for diagnostic and/or therapeutic purposes.
