  • Patent number: 11980386
    Abstract: Versatile tissue collection devices that can provide reduced crossing profiles, fluid pressure release, and/or easy cleaning or removal. In particular, devices having tissue collection devices with multiple configurations to facilitate navigation through narrow vessel cross-sections while also providing adequate tissue storage capacity. Additionally, the devices may include detachable components that allow easy removal, cleaning, and replacement during a procedure. Furthermore, venting elements and sections may be included to relieve fluid buildup in storage reservoirs.

  • Publication number: 20240127381
    Abstract: Machine learning-based techniques for predicting trademark similarity are described. For instance, a first trademark pair comprising an attribute of a first trademark and a corresponding attribute of a second trademark is received. A level of similarity is determined between the first trademark pair and respective second trademark pairs included in respective legal proceedings maintained in a database. A subset of proceedings from the proceedings is selected, each proceeding of the subset including a respective second trademark pair that has the level of similarity with the first trademark pair. A feature vector is generated based on each proceeding of the subset. The feature vector is provided to a machine learning model that outputs a prediction score, based on the feature vector, as to whether a subsequent proceeding would find a likelihood of confusion between the first trademark and the second trademark. The prediction score is provided to a user interface.

  • Patent number: 11406412
    Abstract: An atherectomy catheter includes an elongate flexible catheter body, an elongate deflectable distal tip coupled to the catheter body at a hinge point, a rotatable cutter near the distal end of the catheter body, and a drive shaft extending within the catheter body and configured to rotate the cutter. The atherectomy catheter further includes an optical fiber extending through the drive shaft substantially on-axis with the catheter body and attached to the cutter. The optical fiber is configured to rotate with the drive shaft. The atherectomy catheter further includes a wedge configured to deflect the distal tip away from the catheter body at the hinge point upon axial movement of the drive shaft.
