  • Publication number: 20200030577
    Abstract: A vascular catheter system is provided with a flexible main body and a flexible shaped tip. The tip is located at the distal end of the main body and has at least a portion configured to deviate from a longitudinal axis when in a relaxed state and towards alignment with the longitudinal axis when a guidewire is extended through a lumen of the shaped tip. The shaped tip is no longer than 1 cm and includes at least three sections. The second section is located distally from the first section, and the third section is located distally from the second section. The second section includes a first material having a first durometer and a second material having a second durometer lower than the first durometer. The first section includes the first material without the second material, and the third section includes the second material without the first material.

  • Publication number: 20150157198
    Abstract: Methods and apparatuses for an ophthalmic imaging system are provided. An ophthalmic illumination system with a micro-display projector based head-up display is provided. In accordance with an embodiment, a first optical element is configured to direct light from a light source upon an eye to be examined. A micro-display projector is configured to generate a micro-display image including information associated with the eye to be examined. A third optical element is configured to receive reflected light from the eye resulting from the light directed upon the eye, receive the micro-display image, and transmit at least a portion of the reflected light and at least a portion of light from the micro-display image.

  • Publication number: 20150014047
    Abstract: A method and apparatus for EMI protection is disclosed. Particularly, the present invention is directed to an article of manufacture for electromagnetic interference shielding comprising a cylindrically-shaped sleeve constructed of a conductive fabric adapted to provide electromagnetic interference shielding by conducting at least a portion of electromagnetic radiation, wherein the cylindrically-shaped sleeve is made by rolling a piece of conductive fabric into a cylindrical shape such that opposing sides of the piece of conductive fabric are joined together resulting in the cylindrically-shaped sleeve having a seam at a junction of the opposing sides. In one embodiment, opposing sides of the piece of conductive fabric are sewn together.
