Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
46 words
A method of smoothing a predetermined area of human skin comprising: ablating the epidermal layer of said predetermined area of human skin with a laser beam; and further ablating a portion of the dermal layer originally underlying said ablated epidermal layer to above the papillary dermis.
Claim 2
Independent Claim
46 words
A method of smoothing a predetermined area of human skin comprising: ablating the epidermal layer of said predetermined area of human skin with a laser beam; and further ablating a portion of the dermal layer originally underlying said ablated epidermal layer to above the papillary dermis.
Claim 3
Dependent Claim
25 words
A method as claimed in claim 1 further comprising: cleaning the area ablated to provide a clean ablated area; and protecting said clean ablated area.
Claim 4
Independent Claim
151 words
A method of smoothing a predetermined area of human skin comprising: irradiating a portion of said predetermined area of human skin with a laser beam for a predetermined scan time to ablate the epidermal layer of said portion of said predetermined area of human skin and to further ablate the dermal layer of said portion of said predetermined area of human skin originally underlying said epidermal layer to above the papillary dermis; irradiating a next portion of said predetermined area of human skin for said predetermined scan time to ablate the epidermal layer of said next portion of said predetermined area of human skin and to further ablate the dermal layer of said nest portion of said predetermined area of human skin originally underlying said epidermal layer to above the papillary dermis; and repeating the first and second steps such that said irradiating causes ablation of said skin that is uniform.
Claim 5
Independent Claim
151 words
A method of smoothing a predetermined area of human skin comprising: irradiating a portion of said predetermined area of human skin with a laser beam for a predetermined scan time to ablate the epidermal layer of said portion of said predetermined area of human skin and to further ablate the dermal layer of said portion of said predetermined area of human skin originally underlying said epidermal layer to above the papillary dermis; irradiating a next portion of said predetermined area of human skin for said predetermined scan time to ablate the epidermal layer of said next portion of said predetermined area of human skin and to further ablate the dermal layer of said nest portion of said predetermined area of human skin originally underlying said epidermal layer to above the papillary dermis; and repeating the first and second steps such that said irradiating causes ablation of said skin that is uniform.
Claim 6
Dependent Claim
16 words
A method as claimed in claim 1 in which said laser is a carbon dioxide laser.
Claim 7
Dependent Claim
16 words
A method as claimed in claim 2 in which said laser is a carbon dioxide laser.
Claim 8
Dependent Claim
28 words
A method as claimed in claim 1 further comprising passing said laser beam through an optical waveguide to defocus said laser beam prior to ablating said epidermal layer.
Claim 9
Dependent Claim
25 words
A method as claimed in claim 3 further comprising passing said laser beam through an optical waveguide to defocus said laser beam prior to irradiating.
Claim 10
Dependent Claim
22 words
A method as claimed in claim 1 in which said dermal layer is ablated to a depth of between about 70-200 microns.
Claim 11
Dependent Claim
22 words
A method as claimed in claim 1 in which said dermal layer is ablated to a depth of between about 70-200 microns.
