Abstract: Collapsible branched anastomosis devices allow for the formation of percutaneous vascular anastomoses using a Seldinger wire technique. This minimally invasive approach eliminates the need for a large surgical incision and also avoids the use of time consuming hand-suturing. The devices collapse to a fraction of their expanded volume and are configured to fit within a delivery sheath for over the wire delivery through a small incision in a blood vessel.

Abstract: The system includes a memory card, such as flash memory, containing information which would otherwise be published in conventional book form, such as a textbook, wherein the information on the card is in read-only form, and includes security elements for preventing access to the information by an unauthorized device. The system also includes a display device for receiving the memory card, reading the information in the memory card and displaying the information, wherein the display device is a stand-alone system, incapable of being connected to a network or other system so as to prevent transfer or copying of information from the display device.

Abstract: The system includes a memory card, such as flash memory, containing information which would otherwise be published in conventional book form, such as a textbook, wherein the information on the card is in read-only form and further includes security elements, which prevent unauthorized access to the book content in the card. The system also includes a display device for receiving the memory card, reading the information in the memory card and displaying the information, wherein the display device is a stand-alone system, incapable of being connected to a network or other system so as to prevent transfer or copying of information from the display device. The system further includes a vending machine for dispensing the memory cards in response to a selection by the customer/user, the memory cards including security elements.

Abstract: An electrical testing instrument including a high gain amplifier circuit having a pair of inputs, one comprising a probe and the other covered at least in part by a non-conductive material and being adapted for manual engagement by the user for completing an input circuit through the body of the user. The circuit has a battery and a current-responsive indicator in its output circuit to provide a signal when current flows in the input circuit to provide a critical forward biasing of the amplifier. The battery is connected to furnish such input current when the input terminals are connected in a closed circuit having a resistance of at least approximately the resistance of the user's body. The amplifier circuit is further arranged that when the probe is contacted with a live AC power line and the user engages the portion of the manually engageable input terminal which is covered with a non-conductive material, an operating indicating current will also be present in the output circuit.
