  • Tissue excision device with an independent needle
    Patent number: 9226733
    Abstract: A biopsy device includes a coring cannula, a retract stylet, and a localization needle. The coring cannula has a longitudinal axis and a shaft centered on the axis. The stylet has a tip containing at least one blade and a central passage. The localization needle has a channel and is slidably disposed within the central passage. A drive mechanism rotates the cannula and moves the cannula in a direction parallel to the longitudinal axis of the cannula. A guide element has a first end and a second end and is slidably disposed within the channel of the localization needle. The guide element is movable from a first position to a second position within the localization needle.
