Abstract

A biopsy device includes an elongate needle, a proximal portion, a cutter, and a vacuum conduit. The elongate needle defines an internal passage and includes a distal end and a first plurality of openings along an exterior surface of the elongate needle in communication with the internal passage. The first plurality of openings are sized to admit fluid and to resist the prolapse of tissue. The proximal portion is attached to the elongate needle and is positionable to insert the elongate needle into tissue. The cutter is reciprocally received by the elongate needle to sever a tissue sample received in the elongate needle. The cutter includes a cutter tube with a second plurality of openings in communication with the internal passage of the elongate needle. The vacuum conduit is attached to the proximal portion in communication with the internal passage and is coupled to a vacuum source.
