Publication number: 20220015806Abstract: Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a plate that is seated between the receiver member and the rod and accommodates one or more auxiliary bone anchors that augment the fixation of the assembly's primary bone anchor. Another exemplary assembly can include a hook that extends out from the receiver member to hook onto an anatomical structure or another implant to augment the fixation of the assembly's primary bone anchor. Surgical methods using the bone anchor assemblies described herein are also disclosed.Type: ApplicationFiled: September 29, 2021Publication date: January 20, 2022Applicant: Medos International SarlInventors: J.

Publication number: 20210401450Abstract: Access port cutters and related systems and methods can be used to cut an access port to a desired length based on particular patient and/or surgical procedure needs at a point of use. More particularly, an access port cutter can include a base with an opening that can receive an access port therein such that a desired length of the access port can extend from the opening. An actuation mechanism can translate a blade linearly along at least a portion of the base such that the blade can traverse the opening and cut across the access port. In some embodiments, the actuation mechanism can include a handle that can pivot relative to the base to drive the blade. One or more safety features can reduce the risk of inadvertent actuation of the blade and/or prevent debris from contaminating a surgical site or falling onto a patient.Type: ApplicationFiled: June 30, 2020Publication date: December 30, 2021Inventors: Roman Lomeli, Jae Stelzer, Nicholas Pavento, Alicia McDermott, Paul Maguire, Christopher Ramsay

Patent number: 11191581Abstract: Longitudinally-adjustable bone anchors and related methods are disclosed herein. The ability to adjust a bone anchor longitudinally can allow the surgeon to bring an implanted bone anchor up to the rod instead of or in addition to bringing the rod down to the bone anchor, which can simplify or eliminate the rod contouring step and reduce or eliminate reduction forces. For example, the surgeon can use a pre-bent rod or put “ideal contours” into a rod, lay the rod across a series of bone anchors, and adjust each bone anchor longitudinally to meet the rod. As another example, coarse adjustment of the fixation system can be achieved by contouring the rod and then fine adjustments can be made by bringing each bone anchor up or down to the rod. Various adjustment mechanisms are disclosed, including bone anchors with telescoping portions and bone anchors with risers or spacers.Type: GrantFiled: October 24, 2019Date of Patent: December 7, 2021Assignee: Medos International SarlInventors: Heiko Koller, J.

Publication number: 20210365919Abstract: Various methods, apparatuses/systems, and media for implementing a payment optimizer application module are disclosed. A supplier system accepts a predefined fixed net payment term for all participating buyers on a network. A processor determines weighted average cost of capital (WACC) data of buyer key data points from buyer audited statements data corresponding to a payment file data and WACC data of supplier key data points from supplier audited statements data corresponding to the payment file data. The processor also determines an optimal disbursement date of payment over the predefined fixed net payment term based on the WACC data; applies the stored set of payment rules to determine an optimal payment method corresponding to the WACC data; and automatically executes disbursement of a payment to the supplier in accordance with the optimal disbursement date based on the optimal payment method.Type: ApplicationFiled: May 20, 2021Publication date: November 25, 2021Applicant: JPMorgan Chase Bank, N.A.Inventors: Praveen KUMAR, Christopher RAMSAY, Shashin DALAL, Jacob Allen OLINS, Amit Ramraj SINGH, Vivek B.

Patent number: 11058463Abstract: Implant connectors and related methods are disclosed herein. In some embodiments, a connector can include a low-profile portion to facilitate use of the connector in surgical applications where space is limited. In some embodiments, a connector can include a biased rod-pusher to allow the connector to “snap” onto a rod and/or to “drag” against the rod, e.g., for provisional positioning of the connector prior to locking.Type: GrantFiled: June 17, 2019Date of Patent: July 13, 2021Assignee: Medos International SarlInventors: Kevin Lee, Christopher Ramsay, J.

Publication number: 20210186572Abstract: Articulating implant connectors and related methods are disclosed herein. Exemplary connectors can include first and second bodies that are rotatable relative to one another about a rotation axis and selectively lockable to resist or prevent such rotation. Each of the bodies can be configured to couple to a rod or other fixation component, and the connector can be used to lock first and second rods together even when the rods are obliquely angled with respect to one another.Type: ApplicationFiled: March 3, 2021Publication date: June 24, 2021Inventors: Kevin Lee, Christopher Ramsay, Francisco Amaral, Carl Livorsi, Aubrey Ortiz, Mark Hall, Robert Carruth

Patent number: 11026730Abstract: Bone anchors and related methods are disclosed herein. In some embodiments, a bone anchor can include a drag interface. Exemplary drag interfaces include (i) friction between a shank and a bushing, (ii) friction between a bushing and a drag ring, (iii) friction generated by a biased saddle, and (iv) combinations of the above. The drag interface can help maintain the relative position between a receiver member and a shank of the bone anchor prior to locking the bone anchor, preventing unintended movement while still allowing free movement when intended by the user. In some embodiments, a bone anchor can include over-rotation blocking features, such as a groove, lip, or protrusion formed on a bushing of the bone anchor. Various other bone anchor features are also disclosed, including high aspect ratio drag rings and compressible drag posts.Type: GrantFiled: May 10, 2017Date of Patent: June 8, 2021Assignee: Medos International SarlInventors: Christopher Ramsay, J.

Publication number: 20210085375Abstract: Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.Type: ApplicationFiled: September 25, 2019Publication date: March 25, 2021Inventors: Kevin Lee, Christopher Ramsay, J.
