Abstract
Abstract A marking device provides a circular mark on the skin of the breast of a patient concentric with the areola of the patient's breast. The device is a cylindrical tubular member having an open circular end which is the marking element and having a pair of cross markings at the other end on an optically transparent wall to permit optical centering of the device with respect to the breast areola prior to skin marking. A preferred embodiment includes a pair of markers in a common cylindrical tubular member having one circular diameter at one end and a different circular diameter at the other end.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A device for creating a circular skin-discoloration mark on the surface of a human breast having an areola, said device comprising an optically transparent tubular member open at each end and having a generally circular cross section, one of the open ends of said tubular member having a greater diameter than the other open end; each of the two open ends comprising a circular marking edge; a wall member between the open ends extending across said tubular member substantially normal to the longitudinal central axis of said tubular member and being optically transparent; sighting means on said wall member comprising a pair of cross-markings intersecting at the central longitudinal axis of the said tubular member.
Claim 2
Independent Claim
115 words
A device for creating a circular skin-discoloration mark on the surface of a human breast having an areola, said device comprising an optically transparent tubular member open at each end and having a generally circular cross section, one of the open ends of said tubular member having a greater diameter than the other open end; each of the two open ends comprising a circular marking edge; a wall member between the open ends extending across said tubular member substantially normal to the longitudinal central axis of said tubular member and being optically transparent; sighting means on said wall member comprising a pair of cross-markings intersecting at the central longitudinal axis of the said tubular member.
Claim 3
Dependent Claim
38 words
The marking device of claim 1 wherein the said tubular member is cylindrical adjacent each of its ends and is provided with a central transition region joining the large diameter cylindrical portion with the small diameter cylindrical portion.
Claim 4
Dependent Claim
19 words
The marking device of claim 1 having outwardly extending reinforcing beads on the outer surface of said tubular member.
Claim 5
Dependent Claim
26 words
The marking device of claim 1 including at least one circle mark on the said wall member concentric with the intersection of the two said cross-markings.
Claim 6
Dependent Claim
92 words
A marking device for creating a circular skin-discoloration mark on the surface of a human breast having an areola, said device comprising an optically transparent tubular member having a generally circular cross-section, and being open at one end and having a generally circular cross section, closed by an optically transparent flat wall member at the other end; the open end of said tubular member comprising a circular marking edge; sighting means on said wall member and comprising a pair of cross-markings intersecting at the central longitudinal axis of the said tubular member.
Claim 7
Dependent Claim
92 words
A marking device for creating a circular skin-discoloration mark on the surface of a human breast having an areola, said device comprising an optically transparent tubular member having a generally circular cross-section, and being open at one end and having a generally circular cross section, closed by an optically transparent flat wall member at the other end; the open end of said tubular member comprising a circular marking edge; sighting means on said wall member and comprising a pair of cross-markings intersecting at the central longitudinal axis of the said tubular member.
Claim 8
Dependent Claim
19 words
The marking device of claim 5 having outwardly extending reinforcing beads on the outer surface of said tubular member.
