  • Electromagnetic actuation of elastomeric valve for fluid flow control
    Patent number: 11754196
    Abstract: Actuation of an elastomeric valve with an electromagnet is disclosed wherein an elastomeric valve material may comprise a steel disc embedded in its wall to control the flow of fluid. In response to an electric current being applied to an electromagnet, a magnetic field attracts a disc embedded in the elastomeric valve material. The elastomeric valve would then move towards the electromagnet to create a seal, thereby blocking the flow of fluid.
    Type: Grant

  • Thermally sensitive sleeve
    Patent number: 11015988
    Abstract: A method for providing a temperature sensitive element surrounding a surgical instrument to provide a visual indication of tip temperature to an operator of the instrument. Change in color of the element is an indication to the operator to be aware of the generated heat and reduce power to the instrument accordingly. When the tip of a surgical instrument heats up to a certain threshold that would cause harm, a reversible thermochromic property of the element may change colors in direct relation to the rise and fall of temperature.
