  • Biopsy device having rotational cutting
    Patent number: 8690793
    Abstract: A biopsy device includes a probe assembly and a driver unit. The probe assembly includes a first cannula having a first aperture extending to a lumen proximal to a first distal end of the first cannula. A second cannula has a second aperture extending to a lumen proximal to the second distal end of the second cannula. The second cannula is disposed co-axially with the first cannula. A least one of the first aperture and the second aperture has a cutting edge. The driver unit is configured for releasably mounting the probe assembly. The driver unit is operatively configured to simultaneously rotate the first cannula and the second cannula at different rotational velocities so that the first aperture and the second aperture periodically come into alignment to form a virtual tissue sample aperture.

  • Biopsy tissue marker
    Patent number: 8311610
    Abstract: A biopsy site marker is disclosed. The biopsy site marker includes a first marker element and a second marker element. The first marker element is configured for detection by a first imaging modality. The second marker element is configured for detection by a second imaging modality different from the first imaging modality. The second marker element may be a non-absorbable wire having a predetermined shape and is substantially engaged with the first marker element.
