Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A device for the removal of subcutaneous adipose layers, the device comprising: a hollow needle with a sharp tip forming piercing means for mechanically piercing skin of a patient and the adipose layers said hollow needle having curling at an end part; a laser source means including a laser source having emitting characteristics for generating a laser beam that causes the lipolysis of adipose cells to transform the adipose cells into a liquid; and optical fiber means including an optical fiber connected to said laser source and connected to said needle to convey the laser beam from said source toward said sharp tip of said needle.
Claim 2
Independent Claim
106 words
A device for the removal of subcutaneous adipose layers, the device comprising: a hollow needle with a sharp tip forming piercing means for mechanically piercing skin of a patient and the adipose layers said hollow needle having curling at an end part; a laser source means including a laser source having emitting characteristics for generating a laser beam that causes the lipolysis of adipose cells to transform the adipose cells into a liquid; and optical fiber means including an optical fiber connected to said laser source and connected to said needle to convey the laser beam from said source toward said sharp tip of said needle.
Claim 3
Dependent Claim
39 words
The device as claimed in claim 1, further comprising a hand unit connected to said needle, said optical fiber means being positioned inside said hollow needle for emitting said laser beam out of an inside of said hollow needle.
Claim 4
Dependent Claim
31 words
The device as claimed in claim 1, wherein said laser source means emits at a wavelength between 0.75 and 2.5 micrometers, and at an energy level between 30-300 mjoules per pulse.
Claim 5
Dependent Claim
27 words
The device as claimed in claim 1, wherein said laser source means emits a pulsed beam with an energy level between 30 and 300 mjoules per pulse.
Claim 6
Dependent Claim
49 words
The device as claimed in claim 1, further comprising: another laser source means having an another laser source with emitting characteristics for generating a laser beam in the visible range; and conveying means for conveying the light emitted by said another laser source to said end of said needle.
Claim 7
Dependent Claim
15 words
The device as claimed in claim 5, wherein said conveying means includes another optical fiber.
Claim 8
Dependent Claim
52 words
The device as claimed in claim 6, wherein said another optical fiber is connected to said optical fiber at a location spaced from said sharp tip, said optical fiber exclusively conveying beams generated by said laser source and said another laser source form said location toward said sharp tip of said needle.
Claim 9
Dependent Claim
32 words
The device as claimed in claim 1, wherein said laser source means emits at a wavelength between 0.75 and 2.5 micrometers and at an energy level of 100 mjoules for 200 microseconds.
