Patent number: 11215428Abstract: An example barrier can be switchable between an at least partially collapsed state and at least partially expanded state (e.g., a deployed state). For example, the barrier can be formed from a continuous sheet and a plurality of rigid sections (e.g., rigid panels) attached or incorporated into the continuous sheet. The barrier can also include a plurality of hinges, such as hinge lines, between the panels that are formed from the continuous sheet. The hinges enable the barrier to be rigid foldable (e.g., the hinges can fold and unfold while the rigid sections remain stiff and rigid) between the expanded and collapsed states.Type: GrantFiled: September 6, 2017Date of Patent: January 4, 2022Assignee: BRIGHAM YOUNG UNIVERSITYInventors: Larry L. Howell, Spencer P. Magleby, David C. Morgan, Terri Bateman, Jeffrey E. Niven, Alex Avila, Erica Crampton, Kyler Tolman, Jacob Greenwood, Peter Schleede

Publication number: 20210369371Abstract: The embodiments described herein can be used in a variety of grasping, cutting, and manipulating operations. In some embodiments, an apparatus includes a shaft, a tool member, and a flexure. The shaft has a distal end portion and a proximal end portion, and defines a longitudinal axis. The distal end portion includes a ground portion. The tool member has an engagement portion and an actuation portion. The engagement portion is disposed distally from the actuation portion, and can exert an engagement force on a target structure. The actuation portion receives an actuation force. The flexure has a first end portion coupled to the ground portion of the shaft, and a second end portion coupled to the tool member. The flexure is configured to deform elastically when the actuation force is exerted on the actuation portion of the tool member such that the tool member rotates relative to the shaft.Type: ApplicationFiled: August 16, 2021Publication date: December 2, 2021Applicant: Intuitive Surgical Operations, Inc.Inventors: Jason DEARDEN, Jordan TANNER, Clayton GRAMES, Bryce EDMONDSON, Brian D.

Patent number: 10398842Abstract: An auto-injection syringe shaped similar to a credit card and having a biased injection mechanism operable to drive a needle into a user's body by a fixed distance to dispense a dose of fluid at a subcutaneous location. A safety may be provided to avoid undesired actuation of the injection mechanism. After the safety is bypassed, a trigger may be actuated by the user to allow operation of the injection mechanism. A reciprocating needle-cover resists casual view of the needle by the user during and after use of the syringe. A locking mechanism automatically holds the needle-cover at an extended position to isolate the needle from further contact and to resist re-use of the syringe.Type: GrantFiled: February 28, 2017Date of Patent: September 3, 2019Assignee: Brigham Young UniversityInventors: Jeffrey E.
