  • Screwdriver
    Patent number: 11945079
    Abstract: A screwdriver includes a main body and a switch. The main body is coupled to a handle and includes a pair of parallel, spaced apart slots, and a pawl positioned in each slot. Each pawl is biased outwardly by a spring. The switch is pivotable relative to the main body, and the switch includes a groove extending along an arcuate portion of an inner surface. Pivoting the switch in a first direction moves the switch toward a first position in which the groove is positioned in-line with the first pawl. When the switch is in the first position, the first pawl extends outwardly from the slot and engages the internal tooth surface such that application of a torque in a first direction drives a shank in the first direction and application of a torque in the second direction causes the shank to ratchet relative to the main body.

  • Delivery systems and methods of endoluminal delivery of branched vascular endoprosthetic devices
    Patent number: 11559417
    Abstract: A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.

  • Exposure unit and method for exposing photosensitive materials
    Patent number: 5386268
    Abstract: An exposure unit and method for imaging a photosensitive material includes a source of radiation for exposing the photosensitive material to actinic radiation such that the radiation strikes the photosensitive material at a plurality of angles of incidence, and apparatus for moving the radiation source relative to and in a plane parallel to the photosensitive material. The exposure unit also has a reflector for controlling (1) the proportion of (a) radiation having perpendicular angles of incidence to (b) radiation having non-perpendicular angles of incidence, such that the radiation having non-perpendicular angles is increased, and (2) the distribution of non-perpendicular angles of incidence.
