Sun Microsystems, Inc. - Santa Clara CA

International Classification:

H03K 1716

US Classification:

326 30, 326 86, 326 83, 326 63, 326 81, 327108, 327112

Abstract:

Disclosed is an input/output (IO) device having a power supply node, an input node for receiving an input data signal, and an output node for outputting an output data signal generated in response to the input node receiving the input data bit signal. The IO device also includes a pull-up driver coupled to the power supply node and the output node, wherein the pull-up driver comprises an impedance at the output node which is constant for all voltages at the output node. Additionally, the IO device may have a circuit coupled to the input node, the pull-up driver, and the output node. This circuit is configured to generate a signal that is provided to the pull-up driver. The signal generated by the circuit varies as a function of the voltage at the output node.

International Classification:

A61B 17/08

US Classification:

606157, 606200

Abstract:

Methods and devices for blocking orifices and occluding cavities within a patient are provided. The device in one variation comprises first and second tubular members attached to a collapsible sealing element. The device can be placed through an orifice and the collapsible sealing element can be collapsed to seal the orifice. An embolic may be introduced distal to the sealing element to occlude a cavity. The device may incorporate a locking mechanism which can be engaged to lock the sealing element into the collapsed position. The device may incorporate a valve to prevent flow through the tubular members, for example to prevent egress of the embolic from a cavity. The device can be detached to provide a permanent seal of the orifice, and can retain the embolic within the cavity. The device may be used in conjunction with a stent or other retention device to assist the sealing element in maintaining the seal.
