Abstract: An applicator for use in treating a portion of skin includes an applicator tip that has an end configured to contact the portion of skin, a sonic source mechanically coupled to the applicator tip, a heat source thermally coupled to an end of the applicator tip, and a controller. The applicator tip includes a thermally-conductive material. During operation of the applicator, the controller controls operation of the sonic source to impart mechanical movements to the applicator tip at a sonic frequency and controls operation of the heat source to transfer heat to the end of the applicator tip via the thermally-conductive material of the applicator tip.

Abstract: The present disclosure seeks to address the primary problem of long application durations to deliver an effective dose of an active ingredient. The devices combine mechanical motion with electrically induced flux (e.g., iontophoresis). The combination of techniques in a single device can reduce the treatment time required to deliver the active ingredient in an effective dose, or deliver a larger dose over the same duration of application.

Abstract: Dermal infusion devices and methods are provided. The device is configured to direct two different frequencies of oscillating motion (e.g., sonic and ultrasonic) towards the skin of a subject. The combination of the two different frequencies results in improved dermal infusion capabilities and can be used, for example, to effect transdermal delivery of a topical formulation.

Abstract: A power toothbrush (10) is disclosed having a handle (15), battery (12), ultrasonic drive circuit (14), motor (16), control unit (18), and toothbrush head (20). The toothbrush head includes bristles (26) and a waveguide (24) that is operatively connected to an ultrasonic transducer (22). The waveguide facilitates the transmission of acoustic energy into the dental fluid to achieve improved cleaning and stain removal and improved cleaning in interproximal and subgingival regions. In one embodiment an ultrasound transducer module (30) includes a plurality of piezoelectric elements (32, 34) that may be mechanically connected in series, and electrically connected in parallel. One or more contacts (36) connect the elements, and a waveguide structure (50). An impedance matching layer (38) may be provided between the waveguide and the ultrasonic transducer module. The waveguide may be formed from a relatively soft material, for example, a polymer having a hardness between 10 and 65 Shore A.

Abstract: An oral hygiene device having an ultrasound transducer 22 and an acoustic waveguide 24 facilitating the transmission of ultrasonic acoustic energy to fluids in the oral cavity is disclosed. Preferred ultrasound operating parameters for operation in aqueous environments and in dental slurries are disclosed. Devices may incorporate a drive motor 16 for oscillating a device head 23, acoustic waveguide 24 and one or more bristle tuft(s) 26 at sonic frequencies, and preferred sonic operating parameters are also provided. Multi-element piezoelectric transducer assemblies 30, 40, and various control and communications features are disclosed. Oral hygiene devices disclosed herein achieve improved plaque and stain removal from the teeth as well as interproximal and subgingival regions, while enhancing the user experience, massaging the gums, stimulating dental tissue, and disrupting biofilm.

Abstract: Oral hygiene devices employing an ultrasound transducer are disclosed. The device is user-activatable to commence an operating cycle, and has a controller that may provide a timing function and may provide a variable level of ultrasound transducer output during an operating cycle. The controller may provide a monitoring function that is capable of detecting an ultrasound transducer fault condition and alert a user, through a user interface, when an ultrasound transducer fault condition is detected. The controller may be programmed to count the number of device operating cycles or accumulate the total device operating time and activate a transducer replacement signal following a predetermined number of uses or a predetermined accumulated operating time.

Abstract: An electric toothbrush (10) with an adaptive load sensor (12) is disclosed. The toothbrush of this invention includes a brushhead (16) that is vibrated by a drive assembly (18). The load sensor monitors the current drawn by the drive assembly to determine the mechanical load to which the toothbrush is exposed. The load sensor assembly produces an adaptive threshold signal that represents the instantaneous maximum pressure load. If the sensed load voltage exceeds the adaptive threshold signal, the load sensor assembly deenergizes the drive assembly and generates an alarm signal so as to give the user a warning that the toothbrush has been excessively loaded.
