  • Publication number: 20190201216
    Abstract: An interlaminar fixation device (“ILFD”) and related tools for implanting and extracting the ILFD in surgical procedures to provide support for patients having degenerative spinal conditions. The ILFD comprises an implant body, a pair of fixation pin assemblies, and a locking plug. The body may be a boxlike structure made of a material such as polyetheretherketone (PEEK) or other material with similar beneficial properties. An implant-sizing tool is provided for determining the appropriately sized ILFD. An implant-grasper tool is provided for grasping the ILFD for insertion and positioning of the ILFD. A bone-punch tool is provided for creating openings aligned for insertion of fixation pins. A pin-inserter tool is provided for urging fixation pins into position. A locking-plug inserter tool is provided for inserting the locking plug into the body of the ILFD. A locking-plug extractor tool is provided for removing the locking plug.

  • Patent number: 9989044
    Abstract: A fluid end (15) for a multiple reciprocating pump assembly (12) comprises at least three plunger bores (61) or (91) each for receiving a reciprocating plunger (35), each plunger bore having a plunger bore axis (65) or (95). Plunger bores being arranged across the fluid head to define a central plunger bore and lateral plunger bores located on either side of the central plunger bore. Fluid end (15) has suction valve bores (59) or (89), each suction valve bore receiving a suction valve (41) and having a suction valve bore axis (63) or (93). Discharge valve bores (57) or (87), each discharge valve bore receiving a discharge valve (43) and having a discharge valve bore axis (63) or (93). The axes of at least one of suction and discharge valve bores is inwardly offset in the fluid end from its respective plunger bore axis.
