摘要： An electrode catheter is introduced into a hollow anatomical structure, such as a vein, and is positioned at a treatment site within the structure. Tumescent fluid is injected into the tissue surrounding the treatment site to produce tumescence of the surrounding tissue which then compresses the vein. The solution may include an anesthetic, and may further include a vasoconstrictive drug that shrinks blood vessels. The tumescent swelling in the surrounding tissue causes the hollow anatomical structure to become compressed, thereby exsanguinating the treatment site. Energy is applied by an electrode catheter in apposition with the vein wall to create a heating effect. The heating effect causes the hollow anatomical structure to become molded and durably assume the compressed dimensions caused by the tumescent technique. The electrode catheter can be moved within the structure so as to apply energy to a large section of the hollow anatomic structure. In a further aspect, the location of the electrodes is determined by impedance monitoring. Also, temperature sensors at the treatment site are averaged to determine the site temperature.

摘要： A device and method for calibrating a slew rate is disclosed. The slew rate may be for a driver of a bi-directional buffer. A driver outputs a signal having a frequency. A receiver is coupled to the driver. A frequency counter measures the frequency of the signal. A calibrated slew rate is determined by the frequency of a waveform of the signal. Different waveforms may be determined for the pull-up and pull-down calibrations.

摘要： In general, in one aspect, the disclosure describes an apparatus for calibrating signals. The apparatus includes a receiver pair to receive a differential signal and a reference signal and to generate at least one comparison signal reflecting where a first signal of the differential signal and a second signal of the differential signal cross each other with respect to the reference signal. The second signal is a negative compliment of the first signal. The apparatus further includes a phase detector to determine a phase error based on the at least one comparison signal. The apparatus also includes an edge delay control driver pair to adjust the differential signal based on the phase error.
