Method and apparatus for treating cutaneous vascular lesions

Claim 2

Apparatus for treating cutaneous vascular lesions in a target area under a patient's epidermis, said apparatus comprising: a laser beam source means for directing a laser beam against and through a predetermined location of the patient's epidermis to the target area; and a stationary container means for containing a cooling medium and for subjecting the patient's epidermis to the cooling medium at the target area of the patient's epidermis simultaneous with the application of the laser beam thereto, said container being a closed container and positioned directly between said laser beam source means and the target area of the patient's epidermis, but spaced from said laser beam source means.

Claim 3

Apparatus according to claim 1, wherein said container has a body for containing the cooling medium, said body having perforated spaced internal walls, a top for covering said body and a sealing element interposed between and sealed to said body and said top.

Claim 4

Apparatus for treating cutaneous vascular lesions in a target area under a patient's epidermis, said apparatus comprising: a laser beam source means for directing a laser beam against and through a predetermined location of the patient's epidermis to the target area; means for subjecting the patient's epidermis to a cooling medium at the predetermined location of the patient's epidermis simultaneous with the application of the laser beam thereto, said means being positioned between said laser beam source means and the target area; and closed recirculation means for inserting cooling fluid into said subjecting means and for removing heated cooling fluid from said subjecting means and for inserting re-cooled heated cooing fluid into said subjecting means,

Claim 5

Apparatus for treating cutaneous vascular lesions in a target area under a patient's epidermis, said apparatus comprising: a laser beam source means for directing a laser beam against and through a predetermined location of the patient's epidermis to the target area; means for subjecting the patient's epidermis to a cooling medium at the predetermined location of the patient's epidermis simultaneous with the application of the laser beam thereto, said means being positioned between said laser beam source means and the target area; and closed recirculation means for inserting cooling fluid into said subjecting means and for removing heated cooling fluid from said subjecting means and for inserting re-cooled heated cooing fluid into said subjecting means,

Claim 6

Apparatus according to claim 3, wherein said means for subjecting the patient's epidermis to a cooling medium includes a transparent container having a pair of parallel opposite faces and containing a cooling fluid, said transparent container being positioned between said laser beam source and the predetermined location of the patient's epidermis with said pair of opposite faces substantially perpendicular to the laser beam.

Claim 7

Apparatus according to claim 3, wherein said means for subjecting the patient's epidermis to a cooling medium includes a transparent container for containing a cooling fluid positioned between said laser beam source and the predetermined location of the patient's epidermis, an inlet tube for inserting the cooling fluid into said container and an outlet tube for removing heated cooling fluid from said container, to provide a stream of refrigerated cooling fluid flowing in a direction parallel to and adjacent the surface of the patient's epidermis.

Claim 8

Apparatus according to claim 3, wherein said recirculation means is recirculating means for removing heated fluid, then re-cooling the heated fluid and thereafter re-introducing the re-cooled fluid into said subjecting means.

Claim 9

Apparatus according to claim 3, wherein said laser beam source means includes a laser handpiece.

Claim 10

Apparatus according to claim 5, wherein said laser beam source means includes a laser handpiece having an end and said transparent container is attached to said handpiece at said end thereof.

Claim 11

Apparatus according to claim 4, wherein said container is a first container and said fluid is a substantially non-flowing liquid in said first container, and wherein said first container is replaceable with a second container which is similar to said first container when the temperature of said fluid in said first container has risen to a predetermined temperature.

Claim 12

Apparatus according to claim 9, wherein said first and said second containers each is a rectangular, parallel piped structure.

Claim 13

Apparatus according to claim 10, wherein said first and said second containers each has a body containing said fluid and having perforated spaced internal walls, a top for covering said body and a sealing element interposed between and sealed to said body and said top.
