Patent number: 9668717Abstract: A biopsy device and method are provided for obtaining a tissue sample, such as a breast tissue biopsy sample. The biopsy device may include an outer cannula having a distal piercing tip, a cutter lumen, a side tissue port communicating with the cutter lumen, and at least one fluid passageway disposed distally of the side tissue port.

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.

Publication number: 20090216151Abstract: A biopsy probe includes a body portion, a cannula, a tip, and a cutter. The cannula extends relative to the body portion. The cannula has a first lumen configured to receive a cutter and a transverse aperture configured to receive tissue. The cutter is disposed in the first lumen of the cannula, and is configured to translate relative to the cannula. The tip is located on the distal end of the cannula. An opening is formed through the tip. A second lumen extends through the cannula, and is in fluid communication with the opening formed in the tip. Substances or liquids such as medicine may be dispensed to a biopsy site or other location within the body of a patient via the second lumen and the opening in the tip. The second lumen may be fluidly isolated from the first lumen and any other lumen in the cannula.Type: ApplicationFiled: February 27, 2008Publication date: August 27, 2009Inventors: Trevor W. V.

Patent number: 6561983Abstract: A connection union and method for securing together first and second components of an ultrasonic waveguide or blade. The first and second components of the ultrasonic waveguide or blade are formed as complementary components which engage each other with a complementary fitting. Then a compressed fit over the connection union is formed by an electromagnetic metal forming operation which compressively deforms a female coupling member over the connection union. The female coupling member can comprise a separate sleeve which is compressed over the connection union by the electromagnetic metal forming operation. Alternatively, the female coupling member can comprise a terminal end of one of the first and second components which includes a longitudinally extending recess which forms an outer circumferentially extending sleeve which is compressed over the connection union by the electromagnetic metal forming operation.Type: GrantFiled: January 31, 2001Date of Patent: May 13, 2003Assignee: Ethicon Endo-Surgery, Inc.Inventors: Michael D. Cronin, Jean M. Beaupre, Lee E. Reichel, Jonathan E. Tuttle

Patent number: 6206844Abstract: The present invention is directed to an ultrasonic surgical instrument including an improved outer sheath which is removable and which rotateably engages the ultrasonic waveguide to facilitate attachment of the ultrasonic instrument to a handpiece. In particular, in one embodiment of the present invention, an improved sheath includes a first and second sheath pin slots extending from the proximal end of the sheath to first and second sheath pinholes respectively. An ultrasonic surgical instrument according to the present invention further includes a connector pin, the connector pin extending through the first sheath pinhole, a waveguide pinhole and the second sheath pinhole and an attachment hub surrounding the outer sheath, wherein the attachment hub is slideable over the outer sheath. A first pin slot may be positioned on an inner surface of the attachment hub wherein the connector pin engages the first pin slot when the attachment hub is in its proximal most position.Type: GrantFiled: June 25, 1999Date of Patent: March 27, 2001Assignee: Ethicon Endo-Surgery, Inc.Inventors: Lee E.
