Publication number: 20150250514Abstract: Disclosed bone screws include a slotted tip. The slotted design of the tip partially obviates the need for precision while implanting the bone screw. Further, the slotted tip reduces the stiffness differential between the tip of the bone screw and the bone. Yet further, the slotted tip reduces stress concentrations imparted to the bone both during insertion and under bending loads. Moreover, the slotted tip conforms to natural formations within the bone when the bone screw is inserted into the bone. Instrumentation for implanting and orienting the bone screws is also disclosed herein.Type: ApplicationFiled: March 10, 2014Publication date: September 10, 2015Applicant: COORSTEK MEDICAL LLC d/b/a IMDSInventors: Lance Nathan Terrill, Sarah Lynne Lancianese, Tyler Salem, Dain Odegaard

Publication number: 20150250515Abstract: Disclosed bone screws include multiple screw elements engaged together to provide the required strength along a longitudinal direction and the required flexibility in other degrees of freedom. The disclosed bone screws have a low profile. Further, the bone screws allow fine-tuning of the compression to be applied to bones or joints. Instrumentation for implanting and orienting the bone screws is also disclosed herein.Type: ApplicationFiled: March 10, 2014Publication date: September 10, 2015Applicant: COORSTEK MEDICAL LLC d/b/a IMDSInventors: Lance Nathan Terrill, Andrew Douglas Palmer

Patent number: 8864797Abstract: A line lock system may include a line routed through a plate. The plate may have an elongated body with a plurality of passageways. The line is routed to form at least one one-way slide so no knots are required. The system may include filaments routed through the passageways of the plate or around a dogbone feature of the plate. The filaments may be used to toggle the plate after passage through a hole to prevent withdrawal of the plate back through the hole. The system may include a line lock stabilizer or counter-tension tool to stabilize the line lock as the line is adjusted. The system may include a compression limiter to selectively reduce compression in the one-way slide to facilitate adjustment of the line. The line lock stabilizer, counter-tension tool, or compression limiter may be a filament.Type: GrantFiled: September 23, 2011Date of Patent: October 21, 2014Assignee: Coorstek Medical LLCInventors: Daniel F.

Publication number: 20140284016Abstract: A method for creating undercut features in a wax pattern in an investment casting process is disclosed. The method comprises designing a tooling that includes a mold for an object with an aperture and a core corresponding in size and shape of the aperture. Then, the mold is used to injection mold a pattern for the object, wherein the pattern includes an opening corresponding to the aperture. Next, a plug from the core of the tooling is injection molded using the mold. The plug is press-fitted into the opening of the pattern and the opening of the pattern is sealed with the plug.Type: ApplicationFiled: April 16, 2014Publication date: September 25, 2014Applicant: COORSTEK MEDICAL LLC d/b/a IMDSInventor: Stephen Vander Wal

Publication number: 20140271029Abstract: An interlocking interface retains a screw head in a socket to prevent migration of the screw head out of the socket, or to lock the screw head in the socket. The interlocking interface may retain or lock the screw at various polyaxial angles with respect to the socket. The screw head includes external corrugations. The socket includes an internal corrugated structure which interlocks with the external corrugations of the screw head when the screw is at various polyaxial angles with respect to the socket. A counterbore may be adjacent either or both ends of the socket.Type: ApplicationFiled: November 8, 2013Publication date: September 18, 2014Applicant: Coorstek Medical, LLCInventor: Jeffery D. Arnett

Publication number: 20140194879Abstract: A system for preparing a bone for receiving an articulating member is provided. The system includes a superior inferior component, a connection feature, a housing, at least one rotating member and a cutter. The superior inferior component is engaged to a structure. The connection feature is engaged with the superior inferior component. The housing is engaged with the connection feature. The rotating member is configured to rotate within the housing. The first cutter is engaged with the rotating member such that the rotation of the rotating member translates into rotation of the first cutter, wherein the first cutter rotates about an axis that is generally parallel to a natural surface of the bone.Type: ApplicationFiled: March 12, 2014Publication date: July 10, 2014Applicants: Cleveland Clinic Foundation, COORSTEK MEDICAL LLC d/b/a IMDSInventor: Dinesh Koka
