摘要:
A handpiece and method of use for laser-assisted liposuction for melting, disrupting, and removing cellulite and adipose tissue. Electromagnetic energy is used to selectively melt or disrupt cellulite and adipose tissue and 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.
摘要:
A method and apparatus for treating skin disorders includes a source of pulsed near black body electromagnetic energy and a means of delivering this energy to a treatment site. A means for cooling the treatment site is described. The number of pulses and intensity of the energy can be varied. Optical filters are used to limit the spectrum of energy emitted and the filters are cooled to allow high-energy operation. The size of the treatment spot is controlled by a series of apertures.
摘要:
The tympanic membrane can be tightened by directing energy on spots of the tympanic membrane so as to heat up the collagen matrix layer and cause it to shrink. Energy in the frequency range of 1.4 to 2.6 microns, which roughly corresponds to a collagen absorption range of from 10 to 150 cm.sup.-1, is used.
摘要:
Disclosed is a laser spot projector for use with a laser coagulation system in which a laser beam is radiated as a focussed spot into a portion selected to be thermally coagulated. A laser source produces a laser beam, and a focussing lens focusses the laser beam on the selected portion in the form of a focussed laser beam spot. A variator lens is displaceably arranged between the laser source and focussing lens for changing the magnification of the laser spot depending upon the displacement of the variator lens. The variator lens is selectably displaceable to two separate positions where the image point is conjugated with the object point with respect to the variator lens. This arrangement makes it possible to selectably provide two focussed laser beam spots each having a different spot diameter.
摘要:
A method and device to modify tissue in a manner such that it will take on a permanent new shape. Subdermal tissue is heated to approx 60° C. at which point it becomes pliable and moldable and will take on a permanent new shape if allowed to cool and heal in a new position.
摘要:
A method of treating microbial infections, which consists of the steps of sequentially and repeatedly irradiating the microbe with continuous or pulsed infrared radiation and continuous or pulsed cooling such that heat and cold alternatively penetrates to the site of the infection in order to inactivate the pathogen.
摘要:
The present invention describes a method of treating restless leg syndrome by eliminating venous reflux in an underlying vein. The malfunctioning vein can be removed or ablated by inserting a catheter into the vein that transmits sufficient energy to coagulate or ablate the lining of the vein causing it to permanently close, eliminating the source of venous reflux and the symptom of restless leg syndrome.
摘要:
A dental laser assembly having a housing with a first and second laser cavity. The housing also includes an optical output port and a dental optical delivery system optically connected to the port. A first laser is contained within a first laser cavity which, when activated, generates a first laser beam while, similarly, a second laser is contained within a second laser cavity which, when activated, generates a second laser beam. Only one laser, however, is activated at a given time and the output beam from the activated laser is directed to the optical output port in the housing for use in dental applications. The first laser has optical qualities sufficient to perform a first set of dental procedures while the second laser has optical qualities sufficient to perform a second and different set of dental procedures.
摘要:
A fiber optic probe and its use in performing a sclerostomy (forming a small hole in the sclera of an eye) as a treatment of glaucoma. The minimally dimensioned probe is designed to direct laser light out of its side and, as a result, allows a sclerostomy procedure to be performed with minimal trauma to the conjunctiva and other surrounding ocular tissues of the patient. A series of pulses of infrared laser radiation delivered through the side of the probe forms the hole in the sclera.
摘要:
A method of treating inaccessible microbial infections, the method comprising the steps of exposing the microbe, irradiating the microbe with infrared radiation and cooling such that heat inactivates the pathogen and stimulates a wound healing response in the patient.
