  • Patent number: 11439464
    Abstract: The device serves for the controlled conveying of a cable. The device has a housing, having a cover plate, on which are externally mounted a drive wheel and contact wheel which can be radially pressed onto the drive wheel, between which the cable can be clamped. The cable can be conveyed by means of the drive wheel being driven by a drive unit in the interior of the housing. The rotational motion of the drive wheel is guided through a stationary light barrier by means of a counting disc, running synchronously therewith and having radial slots or holes in the circumferential area, for determining the motion and rotational speed of the drive wheel. The cover plate and the housing can be sterilized. The drive unit in the interior of the housing is not sterilizable, yet is completely enclosed by the sterilized housing and cover plate.

    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.

  • Patent number: 10813690
    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: 10799291
    Abstract: A method of treating a mobile target tissue with a laser beam includes: providing a laser device for generating a laser beam and providing an optical fiber having a delivery end for guiding the laser beam to the target tissue; a controller causes the laser device to generate one or more laser pulses substantially along the same longitudinal axis. The controller causes the laser device to provide one or more laser pulses. The one or more pulses are selected to allow a vapor bubble formed by the one or more pulse to expand an amount sufficient to displace a substantial portion of the liquid medium from the space between the delivery end of the fiber and the target tissue. The one or more pulses are delivered to the target tissue through the vapor bubble after the vapor bubble has reached its maximum extent and has begun to collapse to reduce retropulsion of the mobile target tissue.
