Claims
- 1. A radiation delivery module comprising:
a body supportable over a skin surface of a patient; a radiation source mounted to the body and producing a beam of tissue-damaging radiation; said radiation beam creating a radiation spot having a length and a width, said length being at least about 5 times the width.
- 2. The radiation delivery module according to claim 1 wherein:
the body defines a skin surface plane; the radiation beam is directed transverse to and at the skin surface plane; and the length and width of the radiation spot is measured at the skin surface plane.
- 3. The radiation delivery module according to claim 1 wherein the length of the radiation spot is at least about 10 times the width.
- 4. The radiation delivery module according to claim 1 comprising a plurality of radiation sub-sources each creating a radiation beam component.
- 5. The radiation delivery module according to claim 1 wherein the radiation source comprises a cylinder lens as a focusing optical element.
- 6. The radiation delivery module according to claim 1 wherein the radiation source comprises a diode laser source.
- 7. The radiation delivery module according to claim 1 further comprising means for translating said radiation source within said body so said radiation spot moves in a direction generally perpendicular to said length.
- 8. A radiation delivery module comprising:
a body supportable over a skin surface of a patient and defining a skin surface plane; a radiation source mounted to the body, the radiation source comprising a plurality of diode laser radiation sub-sources each creating a radiation beam component, said radiation beam components combining to produce a beam of tissue-damaging radiation directed transverse to and at the skin surface plane; and said radiation beam creating a radiation spot having a length and a width at the skin-contacting plane, said length being at least about 10 times the width.
- 9. A method for treating dermal tissue comprising:
directing a tissue-damaging radiation beam at the skin of a patient to create a radiation spot on the skin having a length and width, the length being at least about 5 times the width; moving the radiation beam along the skin in a direction transverse to the radiation spot length.
- 10. The method according to claim 9 wherein the directing step is carried out with the radiation beam having a focal point located below the skin surface.
- 11. The method according to claim 9 wherein the directing step is carried out with a radiation beam having a radiation spot with the length being at least about 10 times the width.
- 12. The method according to claim 9 wherein the moving step is carried out with the direction being perpendicular to the length of the radiation spot.
- 13. The method according to claim 9 further comprising positioning a radiation delivery module, comprising a body carrying a translatable radiation source, at a chosen location on the skin of a patient, the radiation beam produced by the radiation source.
- 14. The method according to claim 13 wherein the moving step comprises moving the radiation source relative to the body while maintaining the body stationary relative to the skin.
- 15. The method according to claim 9 wherein the directing step is carried out using a plurality of radiation sub-sources each producing a radiation beam component.
- 16. The method according to claim 9 wherein the directing step is carried out using a diode laser.
- 17. A method for treating dermal tissue comprising:
positioning a radiation delivery module, comprising a body carrying a translatable scanned diode laser radiation source, at a chosen location on the skin surface of a patient, the radiation source comprising a plurality of radiation sub-sources each producing a radiation beam component; directing a tissue-damaging radiation beam from the radiation source at the skin of a patient to create a radiation spot on the skin having a length and width, the length being at least about 10 times the width; and moving the radiation beam relative to the body and along the skin in a direction perpendicular to the radiation spot length while maintaining the body stationary relative to the skin.
