Patent number: 10869659Abstract: Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.Type: GrantFiled: October 18, 2017Date of Patent: December 22, 2020Assignee: Medos International SarlInventors: Daniel Thommen, Eric Buehlmann, Joern Richter, Peter Senn, Veronique Christine Zollmann, Thomas Gamache, William Kane, Joseph Amaral, John Pracyk, Bill Horton, John Wright

Patent number: 10869695Abstract: Connectors are disclosed herein that can be used to attach a rod to a bone anchor assembly that is already occupied by a separate rod. Various ways of attaching the connector to the bone anchor assembly are disclosed, including arrangements in which the connector is locked to the bone anchor, arrangements in which the connector is constrained in one or more degrees of freedom relative to the bone anchor, arrangements in which the connector is adjustable in one or more degrees of freedom relative to the bone anchor, and arrangements that include a spherical articulation joint. In some embodiments, attachment of the connector to a bone anchor can be aided with the use of a positioner. The geometry of the connector can be selected to minimize the offset between a first rod received in the bone anchor assembly and a second rod received in the connector, for example using an angled or curved rod recess and/or a fastener, or set screw, that is offset from the center of the rod or angled relative to the bone anchor.Type: GrantFiled: February 20, 2019Date of Patent: December 22, 2020Assignee: Medos International SarlInventors: Robert Carruth, John Dieselman, Kevin Lee, J.

Patent number: 10856967Abstract: A device having one or more adjustable loops or coils associated with an implant body for use in soft tissue reconstructions is provided. One exemplary embodiment of a device includes a body and a suture filament, with the filament being used to form a self-locking sliding knot disposed on a top side of the body and a plurality of adjustable coils that are substantially disposed on the body's bottom side. Terminal ends of the filament located above the body's top side can be passed through an opening of a Lark's Head knot from opposite sides, thus forming a self-locking sliding knot, and then the terminal ends can be tensioned to adjust a circumference of the coils. Changing a coil's circumference changes a location of a ligament graft disposed on the coil. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.Type: GrantFiled: March 30, 2018Date of Patent: December 8, 2020Assignee: MEDOS INTERNATIONAL SÀRLInventors: Mehmet Ziya Sengun, Hugh S.

Patent number: 10806539Abstract: In one embodiment, an impact absorber attaches a reference array of a computer-assisted surgery system to a medical implant. The impact absorber has a coupler that couples the reference array to the implant such that the reference array is rotatable relative to the implant from an undeflected orientation to a deflected orientation when an external impacting force is applied to the reference array, and from the deflected orientation to the undeflected orientation when the external force is removed. The impact absorber has an alignment feature that 1) engages with a corresponding alignment feature so as to align the reference array with the undeflected orientation and 2) disengages from the corresponding alignment feature when the reference array is rotated from the undeflected orientation to the deflected orientation. Allowing the reference array to be returned to the undeflected orientation after it is impacted can avoid a need to recalibrate the system.Type: GrantFiled: May 15, 2019Date of Patent: October 20, 2020Assignee: Medos International SarlInventors: Joern Richter, Laura Naikauskiene

Patent number: 10806498Abstract: Instruments and related methods for breaking reduction tabs are disclosed herein, e.g., for breaking reduction tabs of a bone anchor or other implant. In some embodiments, the instrument can be configured to minimize the space needed to operate the instrument. For example, the instrument can be configured to receive a reduction tab that is to be broken while the instrument is coaxially positioned with respect to a bone anchor receiver to which the reduction tab is attached. As another example, the instrument can have a maximum outer transverse dimension that is less than, equal to, or only slightly greater than a corresponding dimension of a bone anchor from which a reduction tab is to be broken. Guide rods for positioning a tab breaker instrument over a reduction tab are also disclosed.Type: GrantFiled: March 14, 2017Date of Patent: October 20, 2020Assignee: Medos International SarlInventors: Seetal Erramilli, Frank Spratt, Grant Mellor, Chris Culhane, Ben Stungo, Joanna Talis

Publication number: 20200315711Abstract: Systems, devices, and methods are provided for trajectory guidance using instrument position data and planned trajectories into or through a patient's body or an object. Lasers are emitted from a laser system toward the patient's body or object at an area within or proximate to the instrument operator's line of sight. Information about the instrument, including the position of its proximal and distal ends, and the position of the patient's body or object, are used to direct the emission of the lasers in real-time during operation of the instrument. The emitted lasers function as visual cues indicating the manner in which to position the distal and proximal ends of the instrument to properly align with the planned trajectory. A guidance map on the instrument can be used to output visual cues about the position of the distal and proximal ends of the instrument relative to a planned trajectory.Type: ApplicationFiled: April 5, 2019Publication date: October 8, 2020Applicant: Medos International SarlInventors: Joern Richter, Marc Puls, Thomas Gamache
