Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A monocanalicular probe for a lacrimal pathology comprising a duct plug having a symmetry axis and including a flange on one end of said plug, a bulb on another end of said plug, and a neck extending between the flange and the bulb, wherein the flange is inclined at an angle of approximately 130° in relationship with the symmetry axis, the bulb being radially flexible from its resting position toward the symmetry axis, wherein a peg extends laterally from the bulb in a direction approximately perpendicular to the symmetry axis of the plug, a flexible tube being adhered to said peg, said tube having a mandrel on an end thereof.
Claim 2
Dependent Claim
110 words
A monocanalicular probe for a lacrimal pathology comprising a duct plug having a symmetry axis and including a flange on one end of said plug, a bulb on another end of said plug, and a neck extending between the flange and the bulb, wherein the flange is inclined at an angle of approximately 130° in relationship with the symmetry axis, the bulb being radially flexible from its resting position toward the symmetry axis, wherein a peg extends laterally from the bulb in a direction approximately perpendicular to the symmetry axis of the plug, a flexible tube being adhered to said peg, said tube having a mandrel on an end thereof.
