Publication number: 20140100478Abstract: A biopsy device includes a body portion, a tip, at least one blade, and a cutter. The cannula defines at least one lumen. The cannula has a transverse aperture configured to receive tissue. The tip is located at the distal end of the cannula, and may include at least two concave surfaces. The blade extends longitudinally from the tip. A second blade may also extend longitudinally from the tip. Blades may be axially staggered relative to the cannula. Blades may also have lengths that differ from one another. In addition, a blade may have a pointed distal end, or may have a curved distal edge. The configuration of the blade and tip may provide reduced force to penetrate tissue. The blade and tip may produce a cut length that is greater than or equal to the length of the outer perimeter of the cannula.Type: ApplicationFiled: December 10, 2013Publication date: April 10, 2014Applicant: Devicor Medical Products, Inc.Inventors: Trevor W.V. Speeg, Peter Morgan, John A. Hibner, Lee E. Reichel, William A. Garrison, Gavin M. Monson, Michael E. Johnson, JR., Robert F. Weikel, JR., Michael R. Ludzack

Patent number: 7896817Abstract: A biopsy device and method may be used to obtain a tissue sample, such as a breast tissue biopsy sample. The biopsy device includes an outer cannula having a distal piercing tip, a cutter lumen, and a cutter tube that is rotated by an integral motor and manually translated past a side aperture in the outer cannula to sever a tissue sample. A sample capturing structure (e.g., sample barrel) has a plurality of sample cavities (e.g., radially symmetric, revolver handgun orientation) that are manually aligned one at a time to capture one or more samples.Type: GrantFiled: July 25, 2007Date of Patent: March 1, 2011Assignee: Devicor Medical Products, Inc.Inventor: William A.

Publication number: 20090088665Abstract: A biopsy marker introduction assembly is configured for introduction through a specimen retrieval recess into a probe cutter lumen of a handheld breast biopsy handle. Advancing the cutter causes an extending deployment rod to distally translate within an introducer tube of the introduction assembly, pushing a biopsy marker out of a distal end of the probe at a surgical biopsy site. Thereby, the surgeon is able to position the probe and effect deployment of the marker even if using the other hand to position an imaging device such as an ultrasonic transceiver.Type: ApplicationFiled: December 9, 2008Publication date: April 2, 2009Inventors: Andrew T. Beckman, Rick D. Applegate, Michael E. Boehm, William A. Garrison, Douglas N. Ladd
