APPARATUS FOR COLLECTING AND STAGING TISSUE

A tissue collecting and staging apparatus is operable with a minimally invasive percutaneous tissue removal system to collect a mass of tissue bits and provide an ordered, or staged, version of the bulk tissue prior to removal. The apparatus includes a chamber under vacuum and at least one tube having a first end extending into the chamber for receiving tissue bits therein. A tissue collection container is slidably disposed over the first tube end and extends along a portion of the tube within the chamber. As tissue bits are dispensed from the tube into the tissue collection container, the vacuum draws the container away from the first tube end to maintain vacuum within the tube. The resulting collected tissue mass is a staged reconstruction of the bulk tissue prior to removal to facilitate analysis of the tissue by a pathologist.
