Patent number: 8061360Abstract: A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site of a patient. A fluid parameter associated with applying a reduced pressureto the tissue site may be sensed. An audible fluid leak location sound may be generated in response to sensing the fluid parameter. The audible fluid leak location sound may be altered in response to sensing that the fluid parameter changes. By altering the audible fluid leak location sound in response to sensing a change of the fluid parameter, a clinician may detect location of a fluid leak at the drape by applying force to the drape. The force applied to the drape may be a clinician pressing a finger onto an edge of the drape.Type: GrantFiled: September 18, 2007Date of Patent: November 22, 2011Assignee: KCI Licensing, Inc.Inventors: Christopher Brian Locke, Mark Stephen James Beard, David Robson Blandford, Timothy Mark Robinson

Publication number: 20110087245Abstract: A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. An optional suture receiver may be disposed adjacent to the opposite jaw. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The needle may also be configured to retrieve a suture. A retaining mechanism holds a suture in place to be engaged by the needle. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.Type: ApplicationFiled: December 17, 2010Publication date: April 14, 2011Applicant: DEPUY MITEK, INC., A MASSACHUSETTS CORPORATIONInventors: Christopher Weinert, Ron Farkash, Dan Nelsen, Breck Petrillo, Mike Michael Pereira, David Robson, Thomas Weisel, Charles Johnson, David Skinlo

Publication number: 20100295753Abstract: A satellite antenna arrangement for a satellite communication system comprising: a reflector for producing a far field pattern with near-zero field strength at a predetermined location to reject unwanted signals from said predetermined location or minimise signal power transmitted to said predetermined location, the reflector having a surface comprising a stepped profile arranged to generate the near-zero field strength in the predetermined location. The stepped profile may comprise a radial step. The location of the near-zero field strength can be steered by moving the reflector or by adjusting the amplitude and phase of an additional beam that covers substantially the same region as the main beam reflected by the reflector.Type: ApplicationFiled: February 17, 2010Publication date: November 25, 2010Inventors: David Robson, Simon John Stirland

Publication number: 20100147309Abstract: There is provided a tracheal catheter designed so that a suction catheter may be used to suction out any secretions that accumulate in the zone above the balloon. There is further provided a tracheal catheter having a ventilation lumen with a flexible wall to provide a flexible lumen which takes up negligible volume when the catheter is not inserted. The suction catheter may be inserted into the flexible lumen, bending the flexible lumen wall that normally lies substantially flat against the ventilating lumen. As the suction catheter is inserted into the lumen, the lumen opens to accept it. When the catheter is removed, the wall of the flexible lumen moves back into position against the ventilating lumen wall, again taking up negligible volume. There is also provided a method of suctioning the subglottic space of an intubated patient. This involves providing a tube as described above, inserting a catheter into the flexible lumen from the proximal end, and providing suction to the proximal end of the catheter.Type: ApplicationFiled: December 12, 2008Publication date: June 17, 2010Inventors: Brian J. Cuevas, Michael Sleva, Joseph A. Cesa, Scott M. Teixeira, David Robson

Publication number: 20100060546Abstract: A reflector for a reflector antenna is provided for producing a far field pattern with near-zero field strength at a predetermined position, the reflector having a surface comprising a stepped profile for generating the near-zero field strength. The stepped profile may comprise a radial step. The location of the near-zero field strength can be steered by moving the reflector only or by adjusting the amplitude and phase of an additional low resolution beam, produced by, for example, a simple horn, covering the same region.Type: ApplicationFiled: October 8, 2008Publication date: March 11, 2010Inventors: David Robson, Simon John Stirland
