  • Publication number: 20210317933
    Abstract: A fitting includes a first and second threaded fitting component and a conduit gripping device receivable within the first threaded fitting component. A stroke resisting member is integral with the first threaded fitting component and includes a web having a first radial thickness and extending axially inward from the first threaded fitting component to a distal ring portion having a second radial thickness greater than the first radial thickness. A radially extending bearing surface of the distal ring portion axially engages a radially extending portion of the second fitting component when the first and second fitting components are joined together to the first relative axial position. The stroke resisting member resists additional axial stroke of the first and second fitting components, such that a tightening torque beyond the first relative axial position is increased by the axial engagement.

  • Patent number: 11124319
    Abstract: An assembly for deployment and retraction of a panel for outer space environment usage, includes a member secured to the panel with the member having an axis of rotation. Mass component connected to the panel, with panel wrapped about member with mass component positioned a first radial distance from the axis of rotation. Mass component has a mass per unit area greater than a mass per unit area of the panel adjacent to the mass component. With a rate of rotation of the mass component and member being same, the mass component rotates about the axis of rotation at a second radial distance from the axis of rotation, wherein the second radial distance is greater in dimension than the first radial distance. With a rate of rotation of the mass component and the member changed to be different, radial distance of the mass component to the axis of rotation decreases.

  • Publication number: 20210031007
    Abstract: Devices, systems, and methods can articulate catheters and other tools using fluid drive systems that provide robotically coordinated motion. The drive power will often be transmitted from a fluidic driver to the catheter through a series of pneumatic or hydraulic channels and the driver can be isolated from a sterile field by encasing the driver in a sterile housing and directing drive fluid through a sterile junction between the catheter and driver. Interventional physicians can retain tactile feedback by manually advancing the catheter over a wire or the like, and can subsequently bring an interface of the catheter down into engagement with a corresponding driver interface once a therapeutic tool approaches a target site. A sensor may provide signals during manual advancement of the driver and catheter along the catheter axis.

  • Publication number: 20200179652
    Abstract: Devices, systems, and methods for articulating elongate flexible structures such as catheters optionally include an array of fluid-expandable bodies such as balloons. The array can be formed using separate strings of balloons formed along single-lumen balloon tube material. The balloon strings can be twisted together to form a multi-channel bundle, or the balloon strings may be circumferentially separated, each extending axially. Regardless, the balloons along a common lumen may be aligned so as to bend the catheter in a desired lateral direction. The fluid-expandable bodies may include an elastomeric bladder with a fiber braid so that inflation of the bladder shortens the assembly and applies axial tension to articulate the catheter. The elongate flexible structures may be pre-biased so as to form a bend when in a relaxed configuration, with the structures being articulatable from the bend.

  • Patent number: 10279147
    Abstract: Articulation devices, such as comprising pull rings, are provided having improved or increased visibility under conventional visualization techniques, such as fluoroscopy. Such improved visibility is achieved by the presence of at least one insert comprised of a material that is more visible or detectable under imaging techniques than the pull ring. The at least one insert is positionable within a cut-out in the articulation device and fixed into place by a suitable method such as adhesive, soldering, swaging, welding, laser welding, etc. The insert resides within the dimensions of the walls of the pull ring so as to not increase the outer diameter or decrease the inner diameter of the pull ring. This maintains the profile of the overall articulation device.

  • Patent number: 7166125
    Abstract: An intraluminal grafting system having a delivery catheter comprising a flexible elongate tubular member having proximal and distal extremities and a capsule mounted on the distal extremity of the tubular member and including a graft disposed within the capsule. The graft is comprised of a tubular body configured to be secured to a blood vessel by a self expanding attachment system. The attachment system comprises a generally sinusoidal wire frame having apices which extend longitudinally outward from the end of the tubular body apices which are secured within the tubular body. Both the protruding apices and the base apices are formed with helices which bias the attachment system radially outward. The attachment system further includes a plurality of lumen piercing members that are oriented in a responsive relationship to the radially outward bias of the attachment system.

  • Publication number: 20030090083
    Abstract: A removable supplementary hitch pivots into operational position on a trailer tongue in concert with a primary trailer hitch of the dependent vehicle used in pulling the trailer. The secondary hitch includes at least one additional hitch between the trailing vehicle and the dependent vehicle. Another additional hitch is also commonly provided resulting in an additional hitch on either side of the primary hitch. To introduce a measure of tolerance to breaking the connection through unwanted turning of the power vehicle after the secondary hitch is attached between the vehicles, the connection between the bar and the channel may comprise a flexible spring connection that allows the bar to move off parallel to the channel in absorbing unwanted turning forces while biasing the bar to return to its parallel position.

  • Publication number: 20020032391
    Abstract: The present invention comprises a guidewire having a compressible guide section capable of deflecting a catheter to abut a lumen wall. The compressible guide section exerts an outward radial force while it is at least partially compressed within a lumen. The guide section permits a physician to precisely locate a catheter within a body lumen and adjust a catheter tip orientation to be directed to a particular side of a body lumen. A method is disclosed for properly matching a guidewire and a catheter to operate together in the present invention, along with a force measuring instrument to assist in measuring a catheter's resistance force value. This method and systems of the present invention involve determining the exact force relationship between the compressible guide section and the resistance of the catheter in vitro.
