  • Patent number: 7670363
    Abstract: A method and apparatus for protecting an electronic implantable medical device prior to it being implanted in a patient's body. The apparatus affords protection against electronic component damage due to electrostatic discharge and/or physical damage due to improper handling. The apparatus is comprised of a circuit board having conductive surface means for receiving and releasably grasping the electrodes of the medical device to support the device's housing proximate to the surface of the circuit board. First and second conductive paths are formed on the circuit board extending between the first and second conductive surfaces for shunting electrostatic discharge currents to prevent such currents from passing through the device's electronic circuitry. The respective shunt paths include oppositely oriented diodes, preferably comprising diodes which emit light (i.e., LEDs) when current passes therethrough. Additionally, means are provided to enable functional testing of the medical device.

  • Publication number: 20100044894
    Abstract: Prior art processes for producing protein-based capsules (for example, capsules for use in electrophoretic media) tend to be wasteful because they produce many capsules outside the desired size range, which is typically about 20 to 50 ?m. Capsule size distribution and yields can be improved by either (a) emulsifying a water-immiscible phase in a preformed coacervate of the protein; or (b) using a limited coalescence process with colloidal alumina as the surface-active particulate material.
