A radiographic imaging apparatus includes elongated rigid guide rails having equivalent symmetrical shapes. Carriages attached to the guide rails are configured to move along a length of the guide rails and to support a portion of the imaging apparatus and to facilitate movement thereof along the guide rails. A first type spherical bearing assembly allows a gimbaled connection thereto while allowing substantially no axial movement. A second type spherical bearing assembly allows a gimbaled connection thereto while allowing a limited amount of axial movement. Frame mounts are each attached to one of the first type and second type spherical bearing assemblies to facilitate movement having a one sided tolerance along the guide rails.

A flexible connecting system consists of a flexible connecting rod manufactured from a rigid material, a leading segment and a trailing segment. The body has at least one flexible center section, each having at least one slot to provide flexibility. The slot follows a sinuous, serpentine path to form a plurality of interlocking teeth that can follow a helical or a concentric path. One or more flexible sleeves are dimensioned to fit over the connecting rod to prevent the ingress or egress of material. One or both of the ends of the flexible connecting rod and flexible sleeve can be open or sealed.

A biostimulator transport system, such as a biostimulator delivery system, having a swaged torque shaft, is described. The torque shaft includes an outer cable coaxially arranged with an inner coil. The inner coil has a single wire coil extending around a central axis in a first helical direction, and the outer cable has several outer strands that extend around the central axis in a second helical direction that is different than the first helical direction. The outer cable can be swaged to form a close fit to the inner coil. The close fit of the swaged coaxial torque shaft structure can track to a target site through tortuous vessels and efficiently transfer torque from a handle to a docking cap of the biostimulator transport system to drive a biostimulator into the target site. Other embodiments are also described and claimed.

A telescopic table frame part, in particular a height-adjustable table leg (26), comprising an outer tube (12) and an inner tube (10) which can be moved relative to the former and which is guided by means of a sliding guide, characterized in that the sliding guide comprises at least one injection-molded sliding element (24) made from a slide-promoting plastic, a method for producing a sliding guide for guiding an inner tube (10) in an outer tube (12) movable relative thereto of a telescopic table frame part, comprising attaching of at least one sliding element (24) made from a slide-promoting plastic onto the inner surface (23) of the outer tube (12) or onto the outer surface (25) of the inner tube (10) by injection molding, wherein said plastic is introduced into the inside of the inner tube through an injection molding tool access opening (16) in same, and an apparatus for carrying out the method.

A vibration drive device that suppresses an increase in the number of component parts and can be easily downsized. Vibration is excited in a vibration element in pressure contact with a driven element to thereby rotationally move the driven element relative to the vibration element. A bearing rotatably supports the driven element. A first and a second bearing portions are joined to the driven element. The second and a third bearing portions are pressed against each other via rolling elements in a direction along the axis of the bearing. The rolling elements are brought into pressure contact with the first raceway surface of the first bearing portion, the second raceway surface of the second bearing portion, and the third raceway surface of the third bearing portion. One of the second and third bearing portions is integrally formed with the driven element from the same material.

A measuring method for a liquid metal slide bearing is disclosed. In at least one embodiment, the measuring method includes providing a liquid metal slide bearing to be measured, the liquid metal slide bearing including two bearing parts with liquid metal being arranged between the two bearing parts. The method further includes measuring inductance, or a variable associated with the inductance, of the liquid metal slide bearing; and determining a quantity of liquid metal in the liquid metal slide bearing based upon the inductance, or the variable associated with the inductance, measured. Furthermore, a corresponding measuring device, a liquid metal slide bearing and an x-ray tube and an apparatus are disclosed.

A button lock that selectively retains the angle of an object relative to a handle. The button lock is rotatable between an engaged position, where the angle is retained, and a disengaged position, where the object is disengaged from the handle and can pivotally move about the handle to change the angle. In the engaged position, button teeth on the button engage with handle teeth on the handle. In the disengaged position, the button teeth disengage the handle teeth to space the button from the handle and therefore allow free movement of the handle about the button. The button therefore quickly and easily retains the angle between the object and the handle.

A dock for a surgical equipment holder is disclosed. The dock for a surgical equipment holder includes a base having a central arm mount and a lower clamping jaw. The dock for a surgical equipment holder also includes an upper clamp jaw movably coupled to the base. The dock for a surgical equipment holder also includes a central docking arm coupled to the central arm mount and a central ball cup coupled to the to the central docking arm. The dock for a surgical equipment holder also includes a central attachment nut coupled to the central ball cup. The central attachment nut may include an extendable moment arm, and the dock may also include a ball coupled between the central ball cup and the central attachment nut and a surgical equipment holder attached to the ball.

A method of setting a cannula lock. An orientation of a bore of a brake is set by rotating a base and a head of the brake about at least one axis. An actuator is actuated to cause relative movement between the head and the base to engage internal surfaces of the shell to fix the orientation of the bore. A device may be directed through the bore and into tissue along a trajectory established by the orientation of the bore. The actuator may be rotated about its longitudinal axis to move the head and the base away from one another. Anchors coupled to the shell may be embedded into the section of tissue. The actuator may be an extraction tool for extracting a drive ring from the base of the shell to permit unembedding of the anchors from the tissue. The head and the base may be semi-spherical.
