20110166551 | SELECTIVE LYSING OF CELLS USING ULTRASOUND - Described are embodiments that employ ultrasonic energy to selectively lyse larger adipose cells in a suspension containing adipose cells of different sizes resulting in a suspension in which the only viable cells are the small adipose cells and stem cells. Embodiments provide for generating an acoustic standing wave field of sufficient intensity and proper geometry, that high shear stress is induced on the cell membranes of cells larger than a predetermined size. The remaining small adipose cells can be physically separated from the suspension after the suspension is subjected to the acoustic standing wave field. | 07-07-2011 |
20110313345 | ULTRASONIC DEVICE FOR HARVESTING ADIPOSE TISSUE - Described are embodiments of methods and devices for removing adipose tissue from a surgical site or location in a patient's body. The embodiments include a device that is used for infiltration, ultrasound, and aspiration of the surgical site. The device includes a cannula which serves to provide infiltration, conduct ultrasonic energy from an ultrasound generating device, and also provide a conduit for aspiration to a fluid system used for infiltration and collection of fluids. Embodiments provide for a fixed amount of infiltration fluid to be injected into the surgical site in specific ratio with the amount of lipoaspirate to be removed. The fixed amount of ultrasonic energy, both in amplitude and time, is delivered to the surgical site commensurate with the amount of infiltration and aspiration. The device also includes, in embodiments, a guide that limits the depth to which the cannula can be inserted into a patient. | 12-22-2011 |
20120238917 | COMBINATION ULTRASOUND-PHOTOTHERAPY TRANSDUCER - A soundhead of a treatment device is provided that enables a volume of tissue located beneath the soundhead to simultaneously receive ultrasound and light stimulation. According to one embodiment, the soundhead includes an ultrasound transducer, a light source, and a faceplate extending across a face of the transducer for providing a tissue contacting and ultrasound energy coupling surface of the soundhead. The faceplate is transparent or translucent to the light generated by the light source. Alternate embodiments including externally mounted light sources are also disclosed. | 09-20-2012 |
20120271254 | CANISTER FOR AUTOLOGOUS FAT TRANSFER - Described are embodiments of a canister, system, and method of filtering fat. Embodiments include a sidewall that defines a volume, a filter with a screen, a first port, a second port, and at least one vane which allows for manual agitation of lipoaspirate within the volume. The first port is used to draw fluid from below the filter, forcing excess fluid in the lipoaspirate to be quickly extracted. The vane allows the lipoaspirate to be repeatedly drawn over the filter to aide in removing of liquids from fat in the lipoaspirate. The treated fat may then be removed from the volume through an outlet port and reinjected into a patient. | 10-25-2012 |

20130096596 | ULTRASONIC PROBE FOR TREATING CELLULITE - An ultrasonic probe transmits ultrasonic energy along a shaft from a proximate end to a distal end. The ultrasonic probe includes at least one notch on its distal end. Fibrous tissue, such as septa that connect skin layers to muscle layers of animal tissue, can be positioned within the notch so that it is in contact with at least a portion of the distal end of the ultrasonic probe. The ultrasonic energy conducted through the ultrasonic probe to the distal end will sever the fibrous tissue in the notch. The ultrasonic probe is also designed, in embodiments, to fragment or emulsify adipose tissue, as part of an ultrasonic assisted lipoplasty (UAL) procedure. | 04-18-2013 |

The faceplate is transparent or translucent to the light generated by the light source. Alternate embodiments including externally mounted light sources are also disclosed. | 02-27-2014 |
20140121569 | ULTRASONICALLY HEATED PROBE - A surgical device includes a probe having a proximate end configured to connect to an ultrasonic driver assembly that generates ultrasonic vibrational energy, and a shaft for conducting the ultrasonic vibrational energy from the proximate end to a distal end. The device also includes a canula located at least partially over the distal end of the probe. A material is interposed between the probe and the canula for converting the ultrasonic vibrational energy into heat energy. | 05-01-2014 |
