Claim:
1. A guide block for a biopsy or surgical device, the guide block configured to be inserted into a polygonal opening of a grid-like breast receiving pressure plate, the polygonal opening having a plurality of interior sides arranged in a first shape, to guide a tissue-removing device to a desired location within a patient's breast, comprising: a body which has a proximal face with at least a first proximal opening and a second proximal opening, a distal face with at least a first distal opening and a second distal opening, a central longitudinal axis extending between the proximal face and the distal face, and having a body length between the proximal face and the distal face, the body having a plurality of exterior sides that extend along the body length between the proximal face and the distal face, the plurality of exterior sides being in an arrangement to form a polygonal protrusion having a second shape that corresponds to the first shape of the polygonal opening in the grid-like breast receiving pressure plate; a first guide passageway configured to extend within the polygonal protrusion of the guide block along the body length between the first proximal opening in the proximal face and the first distal opening in the distal face, the first guide passageway configured to guide the tissue-removing device; and a second guide passageway configured to guide the tissue-removing device, the second guide passageway configured to extend within the polygonal protrusion of the guide block along the body length between the second opening in the proximal face and the second opening in the distal face, the second guide passageway is coextensive with and configured to overlap the first guide passageway in a direction of extent of the plurality of exterior sides to form a first longitudinal opening between the first guide passageway and the second guide passageway that extends from the proximal face to the distal face.
