Patent number: 9655682Abstract: A computerized system provides assistance for placement of localization markers for medical operations such as ACL repair procedures. The system displays, on a graphical user interface, an image of an anatomical structure and allows identification, via an input device on the graphical user interface, of a set of landmark locations identifying respective anatomical positions within the displayed image of the anatomical structure. The system displays a graphical overlay over the image of the anatomical structure. Placement of the graphical overlay is based on the set of landmark locations. The system displays at least one localization marker within the graphical overlay. The localization marker(s) identify a location for performing a surgical operation associated with the anatomical structure, such as ACL repair surgical operations.Type: GrantFiled: December 8, 2015Date of Patent: May 23, 2017Assignee: Smith & Nephew, Inc.Inventors: Paul Robert Duhamel, Carlos Rodriguez, Charles H. Brown

Patent number: 9546662Abstract: A surgical instrument includes a hub, a rotating member, an impeller, and an impeller enclosure. The hub has a proximal portion and a distal portion and defines a lumen therebetween. The distal portion of the hub includes a sleeve portion configured to rotatably support the rotating member. The rotating member extends through the hub and has a proximal end and a distal end. The proximal end of the rotating member is configured to couple to an external driving mechanism. The impeller is coupled to the distal end of the rotating member and is configured to accelerate fluid flowing into or out of the lumen. The impeller enclosure is coupled to the distal portion of the hub and defines an impeller volume around the impeller. One or more openings are defined around the sleeve portion of the hub such that the lumen is in fluid communication with the impeller volume.Type: GrantFiled: November 20, 2012Date of Patent: January 17, 2017Assignee: Smith & Nephew, Inc.Inventors: Cemal Shener-Irmakoglu, Brian J. Loreth, Rafal Z. Jezierski, Paul Robert Duhamel

Patent number: 9480493Abstract: A dynamic sensing method and apparatus employs microelectromechanical systems (MEMS) and nanoelectromechanical (NEMS) surgical sensors for gathering and reporting surgical parameters pertaining to a drive mechanism of a surgical device, such as speed, rotation, torque and other characteristics of the surgical device. The surgical device employs or affixes the surgical sensor on or about a surgical device for detecting electromechanical characteristics during the surgical procedure. The surgical procedure disposes the medical device in the surgical field responsive to the drive mechanism of a shaver or other endoscopic instrument inserted in a surgical field defined by the surgical procedure.Type: GrantFiled: September 29, 2015Date of Patent: November 1, 2016Assignee: Smith & Nephew, Inc.Inventors: Todd Edward Smith, Paul Robert Duhamel

Patent number: 9456868Abstract: An instrument includes a handle portion, an actuator, a shaft, a rigid member, and an angular control mechanism. The shaft has a proximal end and a distal end with an electrode region, and a flexible region in between. Moving the actuator causes portions of the flexible region distal of a pivot region to bend such that an angular orientation and a radial offset of the electrode region reach an angular orientation and a radial offset, respectively, when the actuator reaches the end position. A distal portion of the rigid member defines the pivot region. Moving the rigid member along the shaft causes the pivot region to translate. The radial offset varies depending on the position of the pivot region.Type: GrantFiled: March 31, 2015Date of Patent: October 4, 2016Assignee: Smith & Nephew, Inc.Inventors: Mathew Erle Mitchell, Christopher D. McDonald, Paul Robert Duhamel

Patent number: 9011429Abstract: An instrument includes a handle portion, an actuator, a shaft, a rigid member, and an angular control mechanism. The shaft has a proximal end and a distal end with an electrode region, and a flexible region in between. Moving the actuator causes portions of the flexible region distal of a pivot region to bend such that an angular orientation and a radial offset of the electrode region reach a maximum angular orientation and a maximum radial offset, respectively, when the actuator reaches the end position. A distal portion of the rigid member defines the pivot region. Moving the rigid member along the shaft causes the pivot region to translate. The maximum radial offset varies depending on the position of the pivot region. The angular control mechanism is configured to control the angular orientation such that the maximum angular orientation is same regardless of the position of the rigid member.Type: GrantFiled: June 7, 2012Date of Patent: April 21, 2015Assignee: Smith & Nephew, Inc.Inventors: Mathew Erle Mitchell, Christopher D.

Patent number: 7245039Abstract: This invention teaches an apparatus, method, means, and computer readable media to address the problem of the inconsistent, unreliable nature of wind, and in particular low-wind speeds, through utilizing a blower and/or startup assist to aid in turning an electricity generating electrical generator during periods of low-wind speed. This generator provides electrical power for an electrolyzer used to generate hydrogen gas from water. Some embodiments include wind speed and direction sensors and control programming and/or circuitry that tracks trends in direction and speed, and anticipate the need to move the direction of the wind-collecting funnel to best take wind into the funnel, and to provide a start-up assist to the wind-powered turbine at a wind speed that is lower than could start rotation of the turbine without assist, or to maintain rotation when the wind temporarily slows below the speed needed to maintain rotation.Type: GrantFiled: December 8, 2005Date of Patent: July 17, 2007Inventor: Robert A.
