Appl. No.:

29/305887

Inventors:

Jeffrey L. Sobiech - San Jose CA, US
David A. Dewey - Sunnyvale CA, US
D. Shane Fitzgibbons - San Jose CA, US

Assignee:

Reliant Technologies, Inc. - Mountain View CA

International Classification:

2402

US Classification:

D24133, D24107, D24209

US Patent:

7862555, Jan 4, 2011

Filed:

Jul 13, 2007

Appl. No.:

11/778012

Inventors:

Kin F. Chan - San Jose CA, US
George Frangineas - Fremont CA, US
David Dewey - Sunnyvale CA, US
Leonard C. DeBenedictis - Palo Alto CA, US

Assignee:

Reliant Technologies - Mountain View CA

International Classification:

A61B 18/20

US Classification:

606 9, 606 10, 606 12, 607 88, 607 89

Abstract:

In a fractional treatment system, an adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements. In one aspect, the fractional treatment is configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue decreases as the tissue is heated by the laser (e. g. , 1480-1640 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 7 cmto about 26 cm.

Assignee:

Lumenis Ltd. - Yokneam

International Classification:

H01S 3/10

US Classification:

372 23, 372 29011, 372 97

Abstract:

A system, apparatus, and method may provide laser beams of two or more wavelengths from diode pumped solid-state laser sources (). The beam paths of these laser beams with different wavelengths, which are generated by the laser sources (), may be aligned along a common optical axis by an optical configuration, to treat at least one target area. Frequency-doubled laser beams, output from a plurality of diode pumped solid state laser cavities, may be passed through fold mirrors (M, M, M), and combined on a common optical axis , using one or more combiner mirrors (M, M, M), to unify the beam paths. Selected laser beams may be delivered to a target using one or more delivery systems.

US Classification:

606 9, 606 3, 606 10, 606 17, 607 88, 607 89

Abstract:

A fractional treatment system can be configured with a laser wavelength that is selected such that absorption of the laser wavelength within the tissue increases as the tissue is heated by the laser (e. g. , 1390-1425 nm). Desirably, the laser wavelength is primarily absorbed within a treated region of skin by water and has a thermally adjusted absorption coefficient within the range of about 8 cmto about 30 cm. An adjustable mechanism can be used to adjust the beam shape, beam numerical aperture, beam focus depth, and/or beam size to affect the treatment depth and or the character of the resulting lesions. The system may be designed to be switchable between a treatment mode that is semi-ablative and a treatment mode that is not semi-ablative. Adjustment of these parameters can improve the efficiency and efficacy of treatment. Illustrative examples of adjustable mechanisms include a set of spacers of different lengths, a rotatable turret with lens elements of different focal distances, an optical zoom lens, and a mechanical adjustment apparatus for adjusting the spacing between two optical lens elements.
