Abstract
A device and method for collecting from a tissue surface, a sample of tissue, including tissue specimens, polyps, or the like. A device body defines a forward-facing tissue receiving opening of substantially predetermined width through which tissue may pass when the opening is near the tissue surface. A severing element is actuatable across the width of the tissue receiving opening when tissue from the surface extends through the opening for severing the tissue from the surface. A storage space proximal of and adjacent the opening is provided for storage of multiple, successively taken samples by repeatedly passing tissue through the opening and actuating the severing element.
