Patent number: 8277503Abstract: 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.Type: GrantFiled: May 7, 2009Date of Patent: October 2, 2012Assignee: Intersect ENT, Inc.Inventor: Francois Lavigne

Patent number: 7402924Abstract: 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.Type: GrantFiled: May 24, 2006Date of Patent: July 22, 2008Assignee: TM4 Inc.Inventors: Louis-Philippe Bibeau, Jane Roundell, Jean-François Lavigne

Patent number: 6543452Abstract: 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.Type: GrantFiled: November 16, 2000Date of Patent: April 8, 2003Assignee: Medilyfe, Inc.Inventor: Francois Lavigne

Patent number: 5897521Abstract: 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.Type: GrantFiled: June 30, 1997Date of Patent: April 27, 1999Assignee: Medilyfe, Inc.Inventor: Francois Lavigne
