Abstract

A method and apparatus that will alter the fibrous strands in the fatty layers of the skin to reduce the appearance of cellulite and adipose tissue. Electromagnetic energy is used to selectively shrink or alternatively photoacoustically ablate the collagen in the constricting bands of connective tissue that causes the dimpled appearance of cellulite and adipose tissue while avoiding damage to the surrounding fatty cells.

Claims

1. A device for the percutaneous treatment of cellulite and adipose tissue with laser energy, the device comprising:

a hollow cannula with a blunt, non-piercing tip at a distal end for placement underneath the skin of a patient, said hollow cannula having an opening at the distal end;

a variable pulse length laser source having emitting characteristics for generating a laser beam that causes the ablation of undesirable connective tissue;

a coated optical fiber having a coated distal firing tip for absorbing laser energy to heat the firing tip of the fiber, the optical fiber connected to said variable pulse length laser source and movably disposed within the hollow cannula to convey the laser beam from said source to the distal firing tip positioned at a point substantially beyond the distal, blunt tip end of the cannula to minimize heating of the blunt tip end of the cannula; and

a Touhy-Borst or equivalent clamp used to fix the length of the optical fiber so that the distal firing tip of the optical fiber can be set past the distal end of the cannula.

2. The device of claim 1 wherein said variable pulse length laser source emits at a wavelength between about 1.3 um and about 1.6 um.

3. A device for the percutaneous treatment of cellulite and adipose tissue with laser energy, the device comprising:

a hollow cannula with a blunt, non-piercing tip at a distal end for placement underneath the skin of a patient, said hollow cannula having an opening at the distal end;

a laser source having emitting characteristics for generating a laser beam that causes the ablation of undesirable connective tissue;

a coated optical fiber having a coated distal firing tip for absorbing laser energy to heat the firing tip of the fiber, the optical fiber connected to said laser source and movably disposed within the hollow cannula to convey the laser beam from said source to the distal firing tip positioned at a point substantially beyond the distal, blunt tip end of the cannula to minimize heating of the blunt tip end of the cannula;

a Touhy-Borst or equivalent clamp used to fix the length of the optical fiber so that the distal firing tip of the optical fiber can be set past the tip at the distal end of the cannula; and

an injector mechanism for delivery of compounds such as for wound healing compounds meseotherapy and lipotherapy or lipodissolve drugs to the treatment site through the hollow cannula.
