Method of treating fat of a patient by radiation

Abstract

An orthopedic infra-red laser medical device and methods of use for applying infra-red energy to an anatomic region of interest located within the body of a patient. The device includes a hollow needle and a housing on which the needle is releasably mounted. The housing includes an infra-red laser source for producing a laser beam and directing the beam through the needle to exit out of the open distal end of the needle. The distal end of the needle is sharp to pierce through the skin of the patient to a position closely adjacent the anatomic region of interest to deliver the infra-red laser beam thereto without any intervening skin and tissue attenuating the infra-red laser beam. The device can be used for various orthopedic purposes and can also be used on fat in a patient to release activated stem cells.

We claim: 
     
         1 . A method of treating fat of a patient by the irradiation of an anatomic region of fat located within the body of the patient, said method comprising:
 a) providing a device comprising a housing and a needle, said needle being an elongated member having a proximal end, a sharpened distal end and a hollow passageway extending therethrough from said proximal end to said distal end, said housing comprising an infra-red laser source located therein arranged when activated to produce a collimated infra-red laser beam to enter into said hollow passageway at said proximal end of said needle and pass therethrough to exit said distal end of said needle;   b) introducing said needle into the body of the patient by causing said sharpened distal end to pierce the skin and underlying tissue so that said distal end of said needle is located at the anatomic region of fat; and   c) activating said laser source to produce said infra-red laser beam in the range of 200 milliwatts to 500 milliwatts of energy, whereupon said infrared laser beam exits said distal end of said needle to impinge said anatomic region of fat without the intervening skin and underlying tissue attenuating said infra-red laser beam.   
     
     
         2 . The method of  claim 1  wherein said the laser source is either a continuous infra-red laser beam or a pulsed infra-red laser beam. 
     
     
         3 . The method of  claim 1  wherein the laser source is arranged to produce a near infra-red laser beam in the range of 0.7 μm to 3.0 μm. 
     
     
         4 . The method of  claim 1  wherein the laser source is arranged to produce a far infra-red laser beam in the range of 50 μm to 1000 μm.
