Abstract: Smoke evacuation system for removal of aerosolized chemical compounds and biological fine particles produced during laser treatment of tissue. The rapid smoke evacuation is achieved by coupling a low capacity vacuum pump to a vacuum valve and a vacuum reservoir to create very high flow rate for very short durations. The opening time of the valve could at least partially overlap the laser pulse duration.

Abstract: A rapid pulsatile smoke extraction system includes a laser handpiece having a sleeve configurable to be applied to tissue; a vacuum pump and a vacuum reservoir; a conduit connecting the reservoir with the sleeve; and a valve inserted in the conduit. A volume of the vacuum reservoir is at least two times larger than a volume of the sleeve, such that operation of the valve supports instantaneous evacuation of smoke and particulate products from the sleeve into the vacuum reservoir.

Abstract: A system for determining biomechanical properties of corneal tissue includes a light source configured to provide an incident light and a confocal microscopy system configured to scan the incident light across a plurality of cross-sections of corneal tissue. The incident light is reflected by the corneal tissue as scattered light. The system also includes a filter or attenuating device configured to block or attenuate the Rayleigh peak frequency of the scattered light, a spectrometer configured to receive the scattered light and process frequency characteristics of the received scattered light to determine a Brillouin frequency shift in response to the Rayleigh peak frequency being blocked or attenuated by the filter or attenuating device, and a processor configured to determine a three-dimensional profile of the corneal tissue according to the determined Brillouin frequency shift. The three-dimensional profile provides an indicator of one or more biomechanical properties of the corneal tissue.

Abstract: In a method for the production of tooth restorations or tooth replacement parts from a non-metallic, inorganic material firstly a modelable material is modeled in plastic form in the mouth of a patient or with use of a model to a shaped part. The molding is then taken from the mouth of the patient or removed from the model and hardened to a ceramic tooth restoration or a tooth replacement part.
