Abstract

One embodiment of a multifunction aspiration biopsy device includes a hub having a chamber for receiving a collected specimen, a vacuum source in communication with the hub chamber, a needle detachable from the hub and having an outlet in communication with the hub chamber, and a cover extending over a portion of the needle outlet for directing a specimen collected through the needle into the hub chamber in a direction that differs from a longitudinal axis of the needle. The hub chamber with collected specimen may be separated from the vacuum source and the needle and the specimen may be triaged within the hub chamber. Various embodiments of a collection container for receiving used needles are also disclosed.

Description

[0001] This application claims priority to US Patent Application Serial No. 61 / 516,971, filed April 11, 2011, and US Patent Application Serial No. 61 / 629,022, filed November 12, 2011. technical field [0002] The present invention relates to a multifunctional suction biopsy device and methods of use thereof. Background technique [0003] Fine needle aspiration (FNA) is a widely used screening diagnostic procedure. However, only a limited amount of material can be obtained by FNA. Current processes employed in clinical laboratories do not take full advantage of this limited material. Therefore, a preliminary examination or screening is usually only possible if sufficient material has been obtained. The limited material available through this procedure greatly limits further classification of the disease, necessitating more invasive medical procedures to obtain a more conclusive diagnosis. This not only increases the cost, but more seriously delays the diagnosis of the dise...
