Patent number: 8224424Abstract: The invention is directed biopsy site markers and methods of marking a biopsy site, so that the location of the biopsy cavity is readily visible by conventional imaging methods, particularly by ultrasonic imaging. The biopsy site markers of the invention have high ultrasound reflectivity, presenting a substantial acoustic signature from a small marker, so as to avoid obscuring diagnostic tissue features in subsequent imaging studies, and can be readily distinguished from biological features. The several disclosed embodiments of the biopsy site marker of the invention have a high contrast of acoustic impedance as placed in a tissue site, so as to efficiently reflect and scatter ultrasonic energy, and preferably include gas-filled internal pores. The markers may have a non-uniform surface contour to enhance the acoustic signature. The markers have a characteristic form which is recognizably artificial during medical imaging.Type: GrantFiled: July 13, 2009Date of Patent: July 17, 2012Assignee: Senorx, Inc.Inventors: Fred H. Burbank, Paul Lubock, Michael L. Jones, Richard L. Quick, Frank Louw, Stephen A. De Santis

Patent number: 5560373Abstract: A needle core biopsy instrument/extractor for extracting a tissue sample via needle aspiration is disclosed. The extractor comprises a first cannula having a sharpened, beveled cutting tip and biopsy reservoir formed on it distal end. The proximal end of the first cannula is in fluid communication with a conventional syringe such that when the plunger of the syringe is retracted via manipulation o the extractor, a vacuum is created within the biopsy reservoir of the first cannula Axially mounted about the first cannula is a second cutting cannula which is designed and configured to selectively cover and uncover the distal end of the first cannula. A biasing member, preferably a spring, is provided to urge the second cannula forward about the distal end of the first cannula. The syringe, coaxially positioned first and second cannulas, and biasing member are contained within an introducer which is preferably designed and configured to be manipulated by one hand.Type: GrantFiled: April 6, 1995Date of Patent: October 1, 1996Inventor: Stephen A.

Patent number: 5469860Abstract: A fine needle aspiration cytology device for extracting tissue samples for cytologic evaluation is disclosed. The device comprises a handle and generally U-shaped slide member with trigger attachable thereto. The handle is designed and configured to releasably engage a conventional syringe. The slide is designed to slidably engage with the handle and is provided with a slot at the base thereof for retaining the plunger of the When interconnected, the slide may move in forward or rearward positions relative the handle and further, when interconnected with a syringe, may selectively control the axial position of the plunger relative the syringe. In a preferred embodiment, the device is further provided with a manually adjustable locking detent mechanism that may releasably maintain the handle and slide in rigid connection.Type: GrantFiled: October 27, 1994Date of Patent: November 28, 1995Inventor: Stephen A.
