Abstract
A method of marking a cavity in a breast for subsequent visualization may include steps of providing a device having a delivery opening, a first marker and a second marker, the first and second markers being movable through the delivery opening, the first marker being configured to be visualized by ultrasound and the second marker configured to be radiopaque, the first and second markers being free to move relative to one another; introducing the device into a breast so that the delivery opening is positioned in a cavity formed in the breast; and moving the first marker and the second marker through the delivery opening and into the cavity in the breast, the first and second markers being free to move relative to one another when delivered into the cavity so that the first and second markers may take a number of different positions relative to one another when positioned within the cavity.
