  • Publication number: 20250090242
    Abstract: Devices, systems, and methods are provided for registering image data with robotic data for image-guided robotic catheters and other elongate bodies. Fluid drive systems can be used to provide robotically coordinated motion. Precise control over catheter-supported tools is enhanced by alignment of fluoroscopic and ultrasound image data, particularly for structural heart and other therapies in which the catheter will interact with soft tissues. A marker plate having a planar array of machine-readable 2D barcode markers may facilitate alignment of image and robotic data. Determining an ultrasound-based pose of a component in the ultrasound image field allows that component to effectively a fiducial for alignment.

  • Publication number: 20250092511
    Abstract: A vapor deposition system is described. The vapor deposition system includes a reaction chamber and a reactant delivery subsystem coupled with the reaction chamber. The reaction chamber is configured to retain a substrate therein. The reactant delivery subsystem includes inlets, a pre-reaction region, and outlets. The inlets receive precursors and chalcogen precursor(s). The pre-reaction region is configured to receive the precursors from a portion of the inlets and to react at least a portion of the precursors to form modified precursor(s). The modified precursor(s) are more thermally stable than metal-containing precursor(s) of the precursors used to form the modified precursor(s). The outlets are coupled with the reaction chamber and the pre-reaction region. The outlets separately provide the modified precursor(s) and the chalcogen precursor(s) to the reaction chamber. The modified precursor(s) and the chalcogen precursor(s) react and form a chalcogen film on the substrate in the reaction chamber.
