Prepackaged collections of the necessary devices and supplies (i.e., either custom or standard kits) needed for procedures intended to obtain a sample of tissues for in-vitro tests (e.g., biopsy) taken through an endoscope. Items in these kits usually include a specimen collector (e.g., a container with one or more compartments) with a cap; a collection tube that is introduced through the working channel of an endoscope and another tube for connection to the aspiration (i.e., suction) pump (both tubes are attached to the specimen collector); and filters. The kit may also include supplies such as disinfectants and tissue preservation solutions. The kits may be supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottom receptacle with a border around the periphery which supports all the devices and supplies needed for the procedure; the trays are usually covered by a sterile wrap. Endoscopic aspiration procedure kits and trays are mainly used to obtain tissue samples (e.g., polyps) from the colon; the specimen collector is usually appropriate for transportation of the samples to the clinical laboratory for analysis based upon tissue examination. They are used in hospital clinical laboratories, doctors\' offices, and in other healthcare facilities.
