Publication number: 20200046407Abstract: An apparatus for forming a passageway through tissue includes a dilator mounted to a shaft, wherein the dilator includes a first portion, which has an increasing taper from a first outer diameter to a larger second outer diameter, and a second portion, which has a decreasing taper from the first portion to a distal end of the dilator, and which includes an external non-cutting thread formed along the decreasing taper. Lumens of the dilator and shaft provide a conduit for means to pierce through the tissue, for example, an elongate wire that includes a piercing tip. In some cases, the dilator first portion is expandable to, and contractible from, the larger second outer diameter, wherein the apparatus may include a spreading member configured to slide between the shaft and the first portion. The apparatus may be included in a system with an introducer sheath.Type: ApplicationFiled: October 17, 2019Publication date: February 13, 2020Inventors: Ronald A. Drake, Matthew D. Bonner, Trent M.

Publication number: 20200046408Abstract: Modular devices, assemblies, and methods for coupling one or more fixation elements, such as bone fasteners and/or elongate rods. The device includes at least one coupling element having a body portion for receiving a bone fastener and an extension portion extending transversely from the body portion. A locking assembly is received in the coupling element and includes a locking member, a clamp portion, and a ring portion, wherein the locking member is configured to contact an upper portion of the clamp portion and the ring portion is configured to at least partially surround a lower portion of the clamp portion. When unlocked, the bone fastener is moveable within the clamp portion to allow for polyaxial movement of bone fastener relative to the coupling element, and when locked, the bone fastener is fixed relative to the coupling element.Type: ApplicationFiled: October 21, 2019Publication date: February 13, 2020Inventors: Jeff Nichols, Khiem Pham

Publication number: 20200046410Abstract: A rod reducer includes a housing, an anvil, a locking anvil configured to engage a locking plug of a bone screw assembly, an arm assembly, a reducing screw extending through the housing and rotatably coupled with the anvil, and a locking screw extending through the housing and rotatably coupled with the locking anvil. The arm assembly includes an arm hingedly coupled to the housing, and first and second grasping members configured to engage the bone screw assembly. The first and second grasping members are hingedly coupled to the housing and extend through the anvil. Rotation of the reducing screw transitions the arm assembly between an open position, in which, distal portions of the arm and the first and second grasping members are radially expanded, and a closed position, in which, the distal portions of the arm and the first and second grasping members are radially contracted.Type: ApplicationFiled: October 17, 2019Publication date: February 13, 2020Inventors: Kan Min, Brian Kunes

Publication number: 20200046411Abstract: An intramedullary (IM) nail system for the fixation of fractured bones in a patient comprising a nail and compression screws. The length of the body is divided into a distal section and a proximal section with the distal section containing multiple interference sections having a diameter less or greater than that of the body. The threads adjacent the nail head have an apex generally greater than the diameter of the body. The compression screws are dimensioned to be inserted through the bone and contact the nail, pressing it against the bone canal. The nail, once inserted, lies below the surface of the bone.Type: ApplicationFiled: August 9, 2019Publication date: February 13, 2020Inventors: Thomas E. Rushton, Kevin R. Desmond, Mark J. Warburton
