  • Patent number: 11560952
    Abstract: A rotary valve includes a rotary component configured to rotate about an axis of rotation thereof. The rotary component includes a plurality of fluid openings formed at an exterior surface thereof with each of the fluid openings forming a fluid inlet or a fluid outlet into one of a plurality of fluid passageways formed through the rotary component. The rotary component further comprises a valve body rotatably receiving the rotary component therein. The valve body includes a five fluid ports formed therethrough with each of the fluid ports configured to be selectively aligned with one of the fluid openings of the rotary component depending on a rotational position of the rotary component relative to the valve body to allow the rotary valve to operate as a five-way switching valve.

  • Patent number: 7828807
    Abstract: One embodiment is directed to instrumentation for performance of a spinal implantation procedure. In one form, this instrumentation includes: a tube device with an inner surface defining a passage from a proximal end portion to a distal end portion, a conveyor including a threaded conveying rod to be received in the passage of the tube device that can be rotated in the tube or moved in translation along the passage, and a deformable prosthesis structured to move through the passage of the tube by rotating the threaded conveying rod while at least a portion of the deformable prosthesis is positioned between the inner surface and the rod. Optionally, a tool to maintain position of the tube device can be included that has a jaw mechanism, among other things.
