Abstract
A breast 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 healthy tissue on route to the biopsy site. The use of the stylet blade reduces the trauma to healthy breast tissue. The device further includes a cannula blade and a garrote for forming a cut transverse to the core cut by the cannula blade. A lockout feature prevents the garrote from deploying until after a cutting plane of the garrote has been advanced beyond the end of the guide wire.
