  • Patent number: 8277503
    Abstract: A stent comprises a flexible tube having a proximal end, a distal end, and a passageway extending from said proximal end toward said distal end. A first generally straight tube segment extends from the proximal end while a first generally curved segment extends from an end region of the first generally straight tube segment disposed away from the proximal end of the stent. A second generally straight tube segment extends from an end region of the first curved segment away from the first generally straight tube segment and is arranged at an acute angle relative to the first generally straight tube segment. A second generally curved tube segment extends from one end of the second generally straight tube segment and includes a channel on an exterior surface of the second generally curved tube segment.

  • Patent number: 7402924
    Abstract: A cooling assembly including a generally cylindrical body to be inserted inside the generally cylindrical internal stator of an electric machine is described herein. The body includes a cylindrical external contact surface configured and sized to contact the internal surface of the stator. The bottom surface of the body is machine with a channel that is partially closed by a cover to yield a peripheral fluid passage inside the body. An inlet and an outlet aperture are provided.

  • Publication number: 20050284611
    Abstract: A cooling device to which an electric circuit may be mounted includes a cooling body provided with a front edge having bores forming V-shaped channels inside the body. Intersecting V-shaped channels are closed by plugs to thereby define a continuous cooling circuit inside the cooling body.

  • Patent number: 6543452
    Abstract: A nasal intubation device is used to penetrate a nasal region and provide irrigation and/or medication to the nasal region. This intubation device can also be used in other applications. The intubation device comprises a flexible tube and a distal tip at the distal end of the flexible tube. The distal tip includes flanges forming a generally arrow shape that is capable of penetrating the nasal region and allowing the intubation device to remain within the nasal region. The flexible tube includes a passageway communicating with a perforated region proximate the distal end to provide the irrigation and/or medication. An implantation device, such as a canula-trocart, can be used to implant the intubation device.

  • Patent number: 5897521
    Abstract: An intubation device is used to intubate a body passageway or cavity, such as the maxillary sinus, by ventilating, draining, irrigating, medicating or otherwise treating the body cavity. The intubation device includes a flexible tube, for providing access to the cavity, and an anchoring member disposed at a distal end of the flexible tube, for anchoring the tube to a region of the cavity. The tube includes a curved portion proximate the distal end, and the anchoring member includes one or more flanges extending from the distal end. The curved portion of the tube and one of the flanges form a receiving region adapted to receive and conform to a wall in the body cavity, such as the wall of the maxillary sinus. The method of nasal intubation includes inserting the anchoring member and distal end of the tube through a hole formed in the wall of the maxillary sinus.
