摘要:
An ablation apparatus places electrodes at the perimeter of a cavity. In an embodiment, the alternating electric field is used to expose the cavity to enough energy to ablate the cavity. In an embodiment, two modes are used to expose different regions of the cavity to different amounts of power for so that the thermal effect is more uniform. In an embodiment, the electrodes have a relatively large surface area so as to avoid charring the cavity, but are shaped so as to fit within a body orifice. For example, the diameter of the sheathed housing the electrodes during penetration may be only 5.5 mm.

A fixed reader in communication with a portable reader includes an induction circuit and a microcontroller. The induction circuit receives wireless signals sent by the portable reader, and outputs control signals according to the received wireless signals. The microcontroller is electronically connected to the induction circuit, and activates the fixed reader according to the control signals, to allow the fixed reader to enter into a working state or an idle state.

A stent-graft includes a short tube graft and patch located inside of a primary graft. The patch forms a smooth and reliably sealed transition between the primary graft and the short tube graft. Accordingly, the disruption to fluid, e.g., blood, flowing through the lumen of the primary graft by the short tube graft is minimal. Further, the patch supports the inner end of the short tube graft. Thus, the patch, the short tube graft and the primary graft form a stable three-dimensional structure.

An exemplary power supply circuit (200) for a liquid crystal display device (2) includes a switch control circuit (28) for receiving a control signal from an external control circuit, the control signal controlling the turning on or turning off of the switch control circuit; a first DC/DC converter (27) for adjusting the direct current voltage from an external circuit, outputting an output voltage. The switch control circuit controls switches the power supply of the output voltage to a liquid crystal display panel (20) of the liquid crystal display device.

A testing device for testing a motherboard is provided to include a server, a client terminal computer, a debug card and a receiving device. The server is connected to the client terminal computer, for inquiring test results. The debug card is attached to the motherboard, for getting test data. The receiving device connecting with the debug card transmits the test data to the server via a network. A testing method for testing a motherboard is provided to include the following steps: a debug card getting the test data from the motherboard; sending the test data to a receiving device, the receiving device transmitting the test data to a server, the server collating and analyzing the test data; and a client terminal computer inquiring test results via the server.

An LED flood lamp includes an LED lamp and a primary bracket and an accessorial bracket. The lamp includes a pair of lateral sidewalls. The primary bracket pivotally connects with the lateral sidewalls. The accessorial bracket has one end pivotally connecting with one lateral sidewall, and another end connected to the primary bracket via a fastener. Each of the primary and accessorial brackets defines an elongated slot. The fastener is slidable along the slots of the primary and accessorial brackets to vary an illumination angle of the lamp. The LED lamp has a substrate, a plurality of LED modules mounted on a top surface of the substrate and a heat sink mounted on a bottom surface of the substrate, whereby heat generated by the LED modules can be transferred to the heat sink via the substrate to be dissipated to ambient air.

A stent graft system and method of use includes a stent graft for fixation at an attachment site with graft material defining at least one opening having an opening perimeter; a support attached to the graft material; a guide rail attached around the opening perimeter; and a helical anchor having a plurality of coils with a point at one end. The plurality of coils are rotatable around the guide rail to cause the pointed end of the coils to penetrate the graft material and the adjacent tissue in contact with the stent graft to sew the stent graft to the attachment site.

An LED lamp includes a first heat sink, a second heat sink thermally contacting the first heat sink, and an LED module mounted on the first heat sink. The first heat sink comprises a plate and a plurality of first fins extending from the plate. The plate has a bare area on a top surface thereof. The LED module is mounted on the bare area and surrounded by the first fins of the first heat sink. The second heat sink comprises a base thermally contacting a bottom surface of the plate of the first heat sink and a plurality of second fins arranged at a bottom surface of the base of the second heat sink. Heat pipes are sandwiched between the plate and base of the first and second heat sinks.
摘要:
An endostapler delivery system includes a biasing mechanism to offset or counter forces generated by a stapling device and therefore prevent the stapling device from moving during the firing of the staple. The delivery system includes a catheter having at least one lumen extending there through for receiving the stapling device. The biasing mechanism is an expandable biasing cage having a dome or semi-circular expanded shape provided at the distal portion of the catheter. When expanded, the biasing cage does not block or occlude a vessel, thereby allowing blood flow to continue during the stapling procedure. The endostapler delivery system further includes a steering wire that can be used to bend the catheter shaft.
