Patent ID: 7740593

Claim:
A guide block for a biopsy or surgical device, comprising: a. a body which has a proximal face and a distal face spaced a distance from the proximal face, a central longitudinal axis extending between the proximal and distal face and which has four openings in the proximal face and four corresponding openings in the distal face; b. a first passageway which has a length which extends through and is centrally disposed within the body, a maximum transverse dimension less than the distance between the proximal and distal faces, an opening along the length thereof which is parallel to and concentric with the central longitudinal axis and which extends between and is in fluid communication with one of the four openings in the proximal face and one of the four corresponding openings in the distal face; c. a second passageway which extends through the body, which has a maximum transverse dimension less than the distance between the proximal and distal faces, is spaced from and not in fluid communication with the first passageway, is parallel to the central longitudinal axis and extends between and is in fluid communication with a second of the four openings in the proximal face and a corresponding openings in the distal face; d. a third passageway which has a length which extends through the body, has a maximum transverse dimension less than the distance between the proximal and distal faces, has a longitudinal opening along the length thereof that overlaps and is in fluid communication with the longitudinal opening in the first passageway, is separate and spaced from the second passageway, is parallel to the central longitudinal axis and diagonal to the first passageway and extends between and is in fluid communication with a third of the four openings in the proximal face and a corresponding opening in the distal face; and e. a fourth passageway which extends through the body, which has a maximum transverse dimension less than the distance between the proximal and distal faces, is closer to the first passageway than to the second and the third passageway, is separate from the first, second and third passageways, is parallel to the longitudinal axis and extends between and is in fluid communication with the fourth of the four openings in the proximal face and a corresponding opening in the distal face.
