Abstract: A catheter comprises a catheter shaft having a fluid channel, an ultrasound transducer and a compliant balloon mounted on the catheter shaft and having an interior in fluid communication with the fluid channel and containing the ultrasound transducer. The compliant balloon includes a balloon wall having a working section radially surrounding the ultrasound transducer. The working section has a predetermined straightness when the working section has a first diameter and when the working section has a second diameter that is at least 2 mm greater than the first diameter. Other embodiments are also described and claimed.

Abstract: Described herein are acoustic-based tissue treatment systems, apparatuses, and methods for use therewith. Certain such apparatuses comprise a catheter sized and shaped for delivery through a radial artery including a catheter shaft having distal and proximal ends, a plurality of lumens extending longitudinally through the catheter shaft between the distal and proximal ends thereof, and an ultrasound transducer distally positioned relative to the distal end of the catheter shaft. A balloon may surround the ultrasound transducer and at least one of the plurality of lumens may be configured to provide a cooling fluid to the balloon at a pressure and flow rate sufficient to protect non-target tissue in the blood vessel wall from thermal injury.

Abstract: Disclosed herein are ultrasound transducers that are selectively insulated to thereby enable the transducers to be exposed to an electrically conductive fluid without causing a short circuit between electrodes of the transducers. Such a transducer includes a piezoelectric transducer body having a first surface and a second surface that are spaced apart from one another and do not intersect with one another. The ultrasound transducer also includes a first electrode disposed on the first surface, a second electrode disposed on the second surface, and an electrical insulator covering only one of first and second electrodes and configured to inhibit electrical conduction between the first electrode and the second electrode when the ultrasound transducer is placed within an electrically conductive fluid. Also disclosed are apparatuses and systems that include such a transducer. Related methods are also disclosed herein.

Abstract: Various embodiments provide for recommending products from an electronic catalog that are aesthetically compatible with an existing item in a physical space based on a live camera view of the space, and rendering augmented reality views of the recommended products into the live camera view. Specifically, an image of the existing item is used to search a database of images of designed spaces that includes a corresponding object visually similar to the existing item. The image of the designed space may also include other items that are visually compatible with the corresponding object and therefore visually compatible with the existing item. Thus, the images of the other items are used to search an electronic catalog for available items that are visually similar to the other items and therefore would be visually compatible with the existing item.

Abstract: A color selection image matching system can receive, from a computing device, image data captured by a camera in the user device, where the image data includes one or more colors. The computing device can extrapolate a subset of the colors and receive an indication of a target color to initiate a product search based on the target color. The subset of colors may be determined based on other image data, and selectable color elements may be generated for the subset of colors. In some embodiments, the system may generate a palette of colors visually similar to the target color. The target color and/or palette of colors can be cross-referenced with products colors, based on standardized or quantitative color descriptors, to determine relevant product search results matching the target color, which may be displayed on the user device.

Abstract: Various embodiments of systems and methods to dynamically retrain prediction models based on real time transaction data are described herein. In one aspect, real time application data and status data associated with an entity are obtained. The obtained application data is inputted to a prediction model to produce an assessment of a risk. The obtained status data with the assessed risk are compared. When the obtained payment status data does not match the determined risk, the prediction model is retrained.
