Title: Reusable laparoscopic retrieval mechanism
Inventor: PAGEDAS ANTHONY C
IPC: A61B17/30
Filed: 2001-11-21
Abstract: Various embodiments of a reusable surgical device for retrieving a mass during laparoscopic surgery are shown and described. The surgical device has a wand, a rod attached to the wand near the front by a disengaging connector and extending generally parallel to the wand, and a pouch or bag attached to the wand and rod. A portion of the rod is flexible for bowing out from the wand when the rod is pushed forward. The flexible portion straightens to come close to the wand when the rod is pulled backward. The back of the may be slidably connected to the wand. A bag suitable for sterilizing may be attached to the rod and wand for receiving a mass during surgery. When the rod bows out, the bag is opened. When the rod straightens, the bag is closed to form a seal. Methods of using the surgical device include attaching a bag, engaging the disengaging connector, and inserting the device through a laparoscopic sleeve for enclosure, manipulation, and retrieval of the mass. Further steps include, removing the surgical device from the body cavity, disengaging the disengaging connector, removing the bag, disposing of the mass, and sterilizing the rod, wand and/or bag.        Alternatively, the wand and rod may each be comprised of two individual coaxial sections, with each section being arranged for disengagable, end-to-end attachment with one another.

Title: Electrically operated parking brake apparatus
Inventor: TANIGUCHI MAKOTO
IPC: B60T7/02
Filed: 2002-01-24
Abstract: An electrically operated parking brake apparatus that includes a ball screw mechanism driven by an electric motor so as to move a nut member along a screw-threaded shaft. Two Bowden cables, for example, are connected to left and right ends of an equalizer supported on the nut member via an upper support shaft and a lower support shaft for transmitting brake operation force to wheel brakes. Since an axis of the upper and lower support shafts provided at positions-facing each other across the screw-treaded shaft for swingably supporting the equalizer on the nut member passes through the center of the screw-threaded shaft, and a line connecting portion where the pair of Bowden cables are connected to the equalizer passes through the center of the screw-threaded shaft, the application of an unbalanced load to the screw-threaded shaft is prevented.

Title: Arrangement for pumping an anisotropic laser crystal
Inventor: HOLLEMANN GUNTER
IPC: H01S3/06
Filed: 2002-07-02
Abstract: The object in an arrangement for pumping an anisotropic laser crystal is to reduce the influence of the destruction limit of the laser crystal on increased pump power density and, in this connection, to achieve improved beam quality and increased efficiency of a diode-pumped solid state laser. In so doing, the pump volume and cross-sectional area are kept as small as possible along a length of the crystal corresponding at least approximately to the absorption length.      The arrangement operates with an asymmetric pump beam whose pump beam cross section has different dimensions perpendicular to one another and with a laser beam cross section which is adapted to this asymmetry. That axis of the crystallographic axes of the anisotropic laser crystal in whose direction the highest value of the crystal breaking limit exists is oriented along the greatest temperature gradient in the direction of the smaller dimension of the pump beam cross section.
