  • Patent number: 10905464
    Abstract: In some embodiments an apparatus for providing access for a medical procedure in a patient's body cavity includes a stem configured for insertion through an opening in a body cavity wall. The stem has a bore and a cap is disposed at a proximal end thereof and includes an entry port in communication with the bore which receives an instrument to be inserted into the body cavity. An inflatable annular seal is disposed on the stem proximate the cap and a conduit extends through the cap providing pressurized gas at a first outlet in fluid communication with the body cavity providing insufflation pressure. A second outlet of the conduit is in fluid communication the seal, which when disposed inside the body cavity proximate the wall and inflated by pressurized gas, bears on an inner surface of the wall urging the cap into contact with an outer surface of the wall while sealing the opening.

  • Publication number: 20200209730
    Abstract: In some embodiments, a stereoscopic imaging apparatus includes a tubular housing having a bore extending longitudinally through the housing. First and second image sensors are disposed proximate a distal end of the bore, each including a light sensitive elements on a face and mounted facing laterally outward. The apparatus further includes a first beam steering element associated with the first image sensor and a second beam steering element associated with the second image sensor. The beam steering elements receive light from first and second perspective viewpoints and direct the received light onto the faces of the image sensors forming first and second images. Either the first and second beam steering elements or the first and second image sensors are moveable to cause a change a spacing between or an orientation of the perspective viewpoints to cause sufficient disparity between the first and second images to provide image data including three-dimensional information.

  • Publication number: 20200178792
    Abstract: A refraction device includes a main body, a spherical power lens coupled to the main body, an astigmatic power lens movably coupled to the main body, and a visual display coupled to the main body and oriented toward an optical pathway extending through the spherical power lens and the astigmatic power lens. The visual display is configured to display an image for testing visual acuity.

  • Publication number: 20200154094
    Abstract: In accordance with some embodiments, a stereoscopic imaging apparatus includes a tubular housing configured to be inserted into a confined space and including a bore there through. The apparatus also includes first and second image sensors adjacently mounted on a common sensor circuit substrate sized to be received within the bore, each image sensor including light sensitive elements on a face oriented to capture respective images of an object field from different perspective viewpoints for generating 3D image data. The apparatus includes processing circuit substrates each including processing circuitry for processing signals from the image sensors and sized so as to correspond to size of the sensor circuit substrate.
