  • Patent number: 10365187
    Abstract: An apparatus and method are provided for rapid and precise manipulation and transfer of tiny liquid droplets. by dynamically introducing microstructures with relatively high surface energy to a non-wettable surface, which surface has in-situ switchable adhesion to liquid droplets. By penetrating microstructures on the background surface, the chemical property of the surface is locally modified. Capillary bridges will form between microstructures and liquid droplets which lead to high adhesive forces. When the microstructures are retracted, the capillary bridges either pinch-off or recede, which drastically reduces the adhesion. With proper chemical modification, the surface can either manipulate a liquid droplet in air or in an immiscible carrier liquid. Tiny droplets with volumes down to nanoliter scale can be prepared and dispensed by using the surface.

  • Patent number: 10201455
    Abstract: The present disclosure discussed a handpiece for trans-canal delivery of a therapeutic substance to the inner ear. The handpiece can be inserted into the middle ear via a surgical tympanotomy approach. The handpiece can enable a controlled injection of a therapeutic substance directly through the round window membrane and into the inner ear. The direct delivery of the therapeutic substance to the inner ear can enable the delivery of a precise amount of therapeutic substance into the inner ear. Because the therapeutic substance is delivery directly to the inner ear the delivery of the therapeutic substance is not subject to limitations on molecule size and inconsistent diffusion rates that are present when therapeutic substances are diffused across the round window membrane.

    Abstract: A neural prosthetic device can selectively deliver light to different cortical layers, at different depths, in the brain. The device includes LEDs and corresponding waveguides that can extend into the brain. At least two of the waveguides have different lengths. The neural prosthetic device or other devices can be manufactured by changing the hydrophilicity or lyophilicity of a portion of a substrate layer, then depositing uncured polymer on the treated portion of the substrate layer. The uncured polymer flows under the influence of surface tension to form a volume. The volume is shaped as a dome that extends laterally to a boundary between the treated and untreated portions. The polymer is cured in discrete regions through the substrate layer. The discrete regions extend longitudinally from the substrate layer to a curved surface of the dome. The uncured portion of the polymer is removed. The cured regions form the waveguides.

  • Patent number: 9615875
    Abstract: A surgical instrument for thermally-mediated therapies in targeted tissue volumes and for causing thermal effects in polymer tissue-contacting members. In one embodiment, the instrument has a working end with an interior chamber that is supplied with a biocompatible liquid. An energy source causes a liquid-to-vapor phase change within the interior of the instrument. The vapor phase media then is ejected from the working surface of the instrument, and a controlled vapor-to-liquid phase change in an interface with tissue applies thermal energy substantially equal to the heat of vaporization to ablate tissue. The vapor-to-liquid phase transitions, or internal energy releases, can be provided about thin-film flexible structures for engaging body lumens and cavities. An exemplary embodiment can be used for shrinking, sealing, welding or creating lesions in tissue—while causing limited collateral thermal damage and while totally eliminating electrical current flow in the engaged tissue.
