Device, apparatus, and method of adipose tissue treatment
View Patent ↗An improved procedure for performing liposuction is obtained by utilizing a needle that includes a laser source conductor with one end of the needle being configured for insertion into a target adipose skin volume and the other end being coupled to a laser source. The needle may include one or more channels for extracting the treated adipose area. A vacuum source can be used in the extraction of the treated adipose. Further, the first end of the needle may include a cap or end-piece that reduces the build up of carbon deposits. A temperature sensor may be used as input to adjust the laser power and prevent over exposure.
1. A method for adipose tissue laser treatment, said method comprising:
introducing into a target volume of adipose tissue a needle comprising a light conducting body having a first end being configured for introduction into adipose tissue and a second end, adapted to connect to a source of laser radiation including at least one laser operating in a continuous operation mode (CW) and at least one laser source operating in a pulse operation mode;
causing the at least one laser in operating in continuous operation mode (CW) and the at least one laser source operating in a pulse operation mode to operate substantially simultaneously,
wherein the laser operating in the continuous operation mode (CW) heats up the adipose tissue and the laser source operating in the pulse operation mode induces mechanical stress on the adipose tissue.
2. The method according to claim 1 , wherein the laser operating in the continuous operation mode (CW) and the laser source operating in the pulse operation are at least one of a group of lasers consisting of a Ho—(Holmium) laser, Tm—(Thulium) laser or Er:Yag (Erbium Yttrium Aluminum Garnet) laser.
3. The method according to claim 1 , wherein both laser sources affect the adipose tissue at the location being irradiated.
4. The method according to claim 1 , further comprising monitoring the temperature of the target volume of the adipose tissue and adjusting the at least one laser source to avoid excessive damage to the target volume of adipose tissue; and
wherein monitoring of temperature is performed by a temperature sensor mounted on a cantilever configured to follow the first end of the needle and measure the temperature of the tissue surface.
5. The method according to claim 1 , further comprising operating simultaneously with one or more laser sources, a facility for adipose tissue laser removal.
6. The method according to claim 1 , wherein at least two laser sources with different wavelengths are utilized to reduce bleeding.
7. The method according to claim 6 , wherein the two lasers with different wavelengths are operating at a wavelength of 1,064 micrometers and a group of wavelengths consisting of a wavelength of 0.9 micrometers and a wavelength of 0.532 microns.
8. A disposable needle for introduction into and treatment of adipose tissue through the application of laser energy, the disposable needle comprising:
a light conducting body having a receiving end configured to connect at least to a multiple-source of laser radiation; and
the disposable needle being further configured to be removably coupled to two or more laser sources of the multiple-source of laser radiation, with at least one laser source operating in continuous (CW) operation mode and at least one laser source operating in pulse operation mode and the laser operating in continuous (CS) operation mode and the at least one laser source operating in pulse operation mode operating substantially simultaneously; and
wherein the disposable needle is configured such that when introduced into an adipose tissue, the disposable needle delivers the laser operating in the continuous operation mode (CW) into the adipose tissue to cause the adipose tissue to be heated and the disposable needle delivers the laser source operating in the pulse operation mode such that mechanical stress is induced on the adipose tissue.
9. A method for using the needle of claim 8 , said method comprising:
connecting said needle to at least one source of laser radiation and operating the source of laser radiation;
introducing the needle into a target volume of adipose tissue; and
supplying laser radiation of sufficient power to convert at least a volume of the adipose tissue into a liquid.
10. The disposable needle according to claim 8 , further comprising a temperature sensor located over the treated tissue volume and configured to follow the first end of the needle and measure the temperature of the surface of the tissue over the affected tissue volume.
11. The disposable needle according to claim 8 , wherein the temperature sensor is one of a group of contact sensors or non-contact sensors.
12. The disposable needle according to claim 8 , wherein the temperature sensor provides the temperature reading to a controller that controls laser power coupled to the treated skin volume.
13. The disposable needle according to claim 8 , wherein:
the laser that induces mechanical stress on the adipose tissue is at least one of a group of lasers consisting of a Ho—(Holmium) laser, Tm—(Thulium) laser or Er:Yag (Erbium Yttrium Aluminum Garnet); and
the laser generates pulses in sub-millisecond or millisecond range.
14. The disposable needle according to claim 8 , further comprising at least two lasers with one laser operating at a wavelength of 1,064 micrometer and a second laser operating at least at one of a group of wavelengths consisting of a wavelength of 0.9 micrometers and a wavelength of 0.532 microns.
