Publication number: 20240115455Abstract: A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.Type: ApplicationFiled: September 15, 2023Publication date: April 11, 2024Inventors: Joshua Sigsworth, Matthew Gingras, Eric Ankerud, Brian Morin, Dan Becker, Mark Brodie, Leland Ray Adams, Joseph Paul, Amy T. Potts, J. Derek Riemer

Patent number: 9241698Abstract: An intracorporeal surgical tissue retractor is provided having an anchor selectively deployable in a first tissue not to be retracted and a grasper selectively deployable on a second tissue to be retracted. A longitudinally selectively movable support is threadable through the anchor and attached at a substantially distal end of the movable support to the grasper. A deployment user interface is couplable to the movable support and has a proximal end manipulable by a user extracorporeally and a distal end releasably attachable to both the anchor and the grasper, adapted to intracorporeally deploy the anchor into the first tissue and the grasper onto the second tissue. The user interface includes a first actuator having an anchor positioning tool enabling selective deployment of the anchor in the first tissue, and a second actuator enabling selective opening and closing of the jaws of the grasper.Type: GrantFiled: October 7, 2014Date of Patent: January 26, 2016Assignee: Novatract Surgical, Inc.Inventors: Jeffrey Ransden, Leland Ray Adams, Gregor Weaver, Vincent Mata, III, Adam Lehman
