Patent ID: 8398565

Claim:
A guide block for a biopsy or surgical device, comprising: a. a body which has a proximal face, a distal face, a length between the proximal and distal faces and which has a longitudinal axis extending between the proximal and distal faces; b. a first cylindrically shaped passageway which is centrally disposed within the body, which is open from the proximal face to the distal face, and which is parallel to the longitudinal axis; c. a second cylindrically shaped passageway which is disposed within the body, which is open from the proximal face to the distal face, and which is located vertical or horizontal to the first cylindrically shaped passageway and parallel to the longitudinal axis; d. a third cylindrically shaped passageway which is disposed within the body, which is open from the proximal face to the distal face, which is located diagonal to the first cylindrically shaped passageway and which is configured to be in fluid communication with the first cylindrically shaped passageway through a respective sidewall of the first cylindrically shaped passageway and the third cylindrically shaped passageway, and which is parallel to the longitudinal axis; and e. a fourth cylindrically shaped passageway which is disposed within the body, which is located diagonal to the first cylindrically shaped passageway and in an opposite side of the body from the location of the third cylindrically shaped passageway and which is parallel to the longitudinal axis.
