20080311540 | Method and Device For Removing Biofilms By Microsteaming - A method of removing bio films from a surface is disclosed. The method includes a source of bubbles in a liquid medium being provided. The bubbles having a predetermined size. A source of ultrasound waves at a predetermined frequency also being provided. The bubbles in the liquid medium being output toward the surface. The ultrasound waves also being directed toward the surface so that the bubbles vibrate at the predetermined frequency of the ultrasound waves. The predetermined size of the bubbles is approximately related to the frequency of the ultrasound waves. | 12-18-2008 |
20090017423 | DROPLET JET SYSTEM FOR CLEANSING - The system includes a reservoir for fluid; a droplet generator for creating a stream of fluid droplets from the fluid wherein the velocity of the stream of droplets is within a range of 20 meters per second to 200 meters per second and the size of the droplets is within a range of 5 microns to 200 microns. A nozzle or nozzles direct the stream of droplets to safely clean a selected tooth or teeth surface area. The specific momentum of effective fluid droplets within the stream of fluid droplets is important in safe and effective cleaning. | 01-15-2009 |
20090198223 | SYSTEMS AND METHODS FOR CARDIAC ABLATION USING LASER INDUCED OPTICAL BREAKDOWN - Systems and methods for achieving sub-surface, highly spatially selective cardiac ablation by means of laser induced optical breakdown (LIOB) are disclosed. Damage to non-targeted heart and artery/vein tissue is to be minimized according to the present disclosure. A catheter enters the heart, e.g., via a vein, and catheter location is determined/confirmed. Laser pulses are guided through the optical path within the catheter and, at or near the catheter end, a focusing structure is provided that focuses the laser radiation through the non-targeted vein/heart tissue into the targeted tissue. In the focusing structure, laser induced LIOB occurs and related mechanical effects affect the targeted tissue. | 08-06-2009 |

20100035200 | GAS-ASSISTED SYSTEM FOR FLUID DROPLET GENERATION IN AN ORAL CARE SYSTEM - An oral care system using a stream of fluid droplets for cleaning teeth includes a hand-held portable oral care device having a handle portion with a nozzle at a forward end thereof, a source of dental fluid and a source of pressurized gas, between 10-30 bar, both located in the handle portion. The system also includes a base unit which includes a reservoir tank for pressurized air, a reservoir tank for fluid, and a compressor connected to the gas reservoir. The handle includes valves for controlling the release of pressurized gas and fluid from the handle to the nozzle. Connecting ducts are arranged from the fluid and pressurized gas source to the nozzle such as to accelerate the pressurized gas droplets from the nozzle to a desired velocity. | 02-11-2010 |
20100221196 | METHOD FOR CLEANING DENTAL PLAQUE FROM TEETH USING AN ADHERENT PEELABLE GEL - The method for cleaning dental plaque biofilm from the teeth includes the steps of applying a liquid gellable composition to the teeth, the composition including a positively charged polymer such as chitosan, the liquid composition having a viscosity which results in coverage of substantially all of the exposed areas of the teeth. The liquid composition is then gelled by the addition of a second composition, such as a negatively charged compound. The resulting gelled composition has an adherence to the plaque biofilm which is greater than the adherence between the biofilm and the teeth. The gel layer with the biofilm is peeled off of the teeth, removing the dental plaque. | 09-02-2010 |
