  • Patent number: 10940038
    Abstract: Cataract surgery is in recent years more and more augmented and supported by the application of laser cuts in the eye tissue. Such laser systems are separate units from the phacoemulsification system units that are usually used for cataract extraction. The laser systems require the patient to be positioned under the laser unit and then being moved under the surgical microscope next to the phacoemulsification unit. The here described invention relates to systems combining several aspects of the laser system and the phacoemulsification system. In particular, this invention relates to combining at least some parts of the control system and the housing for both systems and thereby minimizing and optimizing setup time, operating room footprint, patient flow and cost. Furthermore the here disclosed invention relates to integrating the laser system under the surgical microscope and thereby significantly reducing the surgery setup and complexity.

    Abstract: A catheter enables real-time light measurements, for example, without limitation, diffuse reflectance, fluorescence, etc., from biological materials, such as tissue (including blood), while performing RF ablation. The catheter tip design isolates illumination and collection paths within the tip electrode such that light for illuminating the tissue of interest (e.g., cardiac tissue or blood) is isolated within the tip electrode from light that returns from the tissue to the catheter tip, and vice versa. Such a design advantageously avoids saturation of the optical detector, and ensures diffusion of the illumination light within the medium of interest. The catheter has a catheter body and a tip electrode with a shell wall and a hollow cavity. The shell wall has at least an illumination opening and a collection opening.

  • Patent number: 10602960
    Abstract: A device and method are described for navigating and positioning a central venous catheter into the venous system using two different modes of location. For example, a peripherally inserted central catheter (“PICC”) may be navigated and positioned within the superior vena cava. A light emitting element is used in the first mode to navigate the PICC to the superior vena cava. To improve visibility during navigation, the light emitted from the light emitting element may include a narrow range of wavelengths that generally matches the wavelengths of light that are transmissable through a light absorbing material defining the wall of the catheter. A conductive medium is used in the second mode to monitor an ECG signal in order to position the PICC in the superior vena cava. One advantage of this procedure is that X-ray visualization can be eliminated to reduce the danger associated with X-rays.

  • Patent number: 10559077
    Abstract: An image processing apparatus is disclosed, which uses OCT to process a plurality of cross-sectional images obtained by moving an imaging core inside a catheter in an axial direction while rotating the imaging core. Cross-sectional image data is acquired in association with position information in the axial direction when each of the cross-sectional images. A first cross-sectional image in which a disappearance section enabling determination having a disappeared portion of an external elastic membrane included in a vascular tomographic image starts, and a second cross-sectional image in which the disappearance section ends are extracted from the plurality of cross-sectional images. The position information in the axial direction is acquired for the first cross-sectional image and the second cross-sectional image, and an ablation range influenced by ablation at a position associated with the disappearance section is calculated based on a difference in the acquired position information in the axial direction.

  • Patent number: 10543043
    Abstract: The present disclosure relates to a system and method for providing laser energy through a catheter towards a second end portion of the catheter. Based on a characteristic of the laser energy multiple types of ablation therapy may be implemented. A first ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a first characteristic. A second ablation therapy is directed at the target site when the laser energy at the second end portion of the laser energy delivery system has a second characteristic. The first ablation therapy may be an optical ablation therapy wherein the laser energy is directed at the target site as optical energy and the second ablation therapy may be a pressure wave ablation therapy wherein pressure waves are directed at the target site as pressure wave energy.
