Abstract: Cyclic aspiration system including an aspiration catheter and a cyclic aspiration source connected in fluid communication thereto, wherein the cyclic aspiration pressure source produces a cyclic aspiration pressure waveform of intermittently cycling intervals of a vacuum pressure below atmospheric pressure and a positive pressure higher than the vacuum pressure. The system further including a non-powered internal structural impediment disposed within the lumen of the aspiration catheter and configured to engage with a clot capturable therein during resulting movement between the clot and the non-powered internal structural impediment while subject to the cyclic aspiration pressure waveform to assist in capture of the clot. The non-powered internal structural impediment may be permanently attached to the aspiration catheter or a separate component or device independently slidable within the lumen of the aspiration catheter.

The aspiration catheter further includes a stabilizing structural member stabilizing the body relative to the inner wall of the vessel to minimize movement and/or radial expansion of the distal tip of the body while subject to aspiration that otherwise may potentially damage the inner wall of the vessel.

Abstract: Acoustic inspection productivity can be enhanced using techniques to perform compression of acquired acoustic data, such as data corresponding to elementary A-scan or other time-series representations of received acoustic echo data. In various approaches described herein, time-series data can be decimated for efficient storage or transmission. A representation of the time-series data can be reconstructed, such as by using a Fourier transform-based up-sampling technique or a convolutional interpolation filter, as illustrative examples. The techniques described herein can be used for a variety of different acoustic measurement techniques that involve acquisition of time-series data (e.g., A-Scan data). Such techniques include Full Matrix Capture (FMC) applications, plane wave imaging (PWI), or PAUT, as illustrative examples.

Abstract: A floating fastener comprises a retainer and a captive nut held within a cavity of the retainer. The nut is star-shaped with four points spaced equally apart and with four valleys on the periphery of the nut between the points creating the overall star-shape of the nut. Likewise, the cavity in the retainer corresponds to the shape and contour of the nut but sized so that there is a substantial gap between them. Permissible lateral float of the nut can be maximized by employing a particular angularity of the sides of the valleys in relation to other dimensions of the fastener.

Abstract: Disclosed in this specification is an infrared thermometer with multiple probes for use at a variety of bodily sites. The thermometer automatically detects which of the multiple probes is currently attached, loads a predetermined program from memory that corresponds to the current probe, and thereafter obtains a temperature measurement from a patient using infrared radiation emitted therefrom. Each of the probes is comprised of an infrared target which provides a substantially consistent sources of infrared radiation for the thermometer to measure.

Abstract: The diastolic blood pressure and a systolic blood pressure of a vertebrate are measured using an inflatable pressure cuff disposed about a limb of the vertebrate and connected to an inflation device through a single conduit. A pressure sensor is pneumatically connected to the cuff through the same common conduit. The sensed pressures at the diastolic and systolic points are corrected for a pressure differential associated with the flow of an inflation fluid through the common conduit. The sensed pressures at the diastolic point and the systolic point may be measured during inflation of the cuff or during controlled deflation of the cuff.
