Abstract
A biopsy device is provided which includes a localization needle having a guide wire preloaded into the biopsy device. The device includes a stylet having a blade for transecting and separating tissue. The device further includes a cannula for cutting a core of tissue and a garrote wire mechanism for cutting a transection of tissue transverse to the core cut by the cannula. The garrote wire is activated by a trigger mechanism which is locked out by a lockout feature within the device until the garrote wire has been advanced around the core of tissue cut by the cannula.
