  • Patent number: 5158565
    Abstract: A localization needle having an inner and outer needle, the outer needle having a window at the distal end and the inner needle having a barb to project out of the window upon relative axial movement of the needles. A first hub on the inner needle has axially spaced recesses to retain and locate a second hub on the outer needle. The first hub is expandable to allow motion of the second hub from a proximal to a distal position. A manually operable flexible oval within the first hub is used to expand the first hub to allow the relative movement of the second hub.
