摘要:
An apparatus for treating varicose veins includes a catheter (20) where the distal end is placed within a varicose vein and the proximal portion remains outside the body of the subject. A heating element (22) heats the vein. A cooling element (62) can be applied to an external surface of the skin above the vicinity of the heating element. A control unit (26) can drive the heating element to apply heat to the vein simultaneously. Alternatively, the control unit can apply a current to the heating element to resistively heat a resistive element. A method for treating a varicose vein includes inserting the elongated heating element into the vein, and driving the heating element to apply heat to the segment of vein simultaneously from the entire active heating portion.

摘要:
Systems, apparatuses and methods are provided for use in closing punctures in vessel walls. An apparatus may have various combinations of an anchoring device, a positioning device and a heating element for closing a puncture within a vessel wall. An anchoring device may be a balloon, an expansible cage, a wire operated T-anchor, and/or a floating anchor. A positioning device may be a balloon, a sponge, and/or an expansible cage. A heating element may be flexible or rigid and preferably provides heat to target tissue through conduction and convection. A heating element may be flat-ended or dome-shaped. The heating element and anchoring device may be positioned a fixed distance apart to sandwich tissue between the heating element and the anchoring device. The heating element may operate in multiple stages. An initial stage may non-permanently adhere the heating element to the tissue and the subsequent stage may close the puncture.

Systems, apparatus and methods are provided for closing a puncture in a vessel wall may have various combinations of an anchoring device, a gripping device and a heating element for sealing a puncture within a vessel wall. An anchoring device may be a balloon, floating anchor, an expansible cage and/or a wire operated T-anchor. A gripping device may hold and/or twist the vessel wall to secure the vessel wall in place during heating. A heating element may provide heat to target tissue held by the gripping device.

An advanced split ODU architecture is provided. The advanced architecture includes an indoor communication unit including a digital modem assembly configured to modulate and demodulate digital data, and also includes a digital interface module configured to transmit and/or receive the digital data, over a digital communication pathway, between the indoor communication unit and an external outdoor communication unit. The advanced architecture further includes an outdoor communication unit having a digital interface module configured to transmit and/or receive the digital data, over the digital communication pathway, between the outdoor communication unit and an external indoor communication unit, and also includes a digital to analog converter configured to convert the digital data to analog data and an analog to digital converter configured to convert the analog data to the digital data, and further includes an RF module configured to convert the analog data between a baseband and a radio frequency.
摘要:
Some of the embodiments of the present disclosure provide a system-on-chip (SOC) that includes a plurality of processing cores; and a counter update module configured to atomically update a counter that is stored in a storage location, based on a counter update command received from a processing core of the plurality of processing cores; generate an ECC for the updated value of the counter; and write the updated value of the counter and the ECC to the storage location. Other embodiments are also described and claimed.
摘要:
Systems and techniques relating to managing a queue memory include, in some implementations, a method comprising: retrieving stored data from an oldest read entry in a FIFO queue memory having entries formed in hardware upon a first read operation; retrieving stored data from a selected entry in the FIFO queue memory upon a second read operation; and shifting data stored in entries of the FIFO queue memory with respect to the oldest read entry upon the first read operation and with respect to the specified entry upon the second read operation. In addition, some implementations include a queue memory comprising a hardware device having memory entries to receive and store data from a communications interface, wherein the queue memory supports first-in-first-out read operations and out-of-order read operations with data shifting among the entries of the memory relative to a read operation.
