Patent number: 8864785Abstract: A surgical access system for accessing a surgical target site within a spine includes a retractor and an elongated element. The retractor has a closed configuration defining a lumen with an internal circumference, and an open configuration in which the internal circumference, at least at the distal end of the retractor, is enlarged relative to said closed configuration. The open configuration creates and maintains an operative corridor to said target site. The elongated element is releasably coupled to an interior wall of the retractor and has an extension extending distal of the distal end of the retractor into the surgical target site. When coupled to the retractor, the elongated element covers a body structure at the target site without blocking access to the operative corridor.Type: GrantFiled: September 10, 2012Date of Patent: October 21, 2014Assignee: Zimmer Spine, Inc.Inventors: James J. Pagliuca, John D. Unger, Thomas Davison

Patent number: 8852234Abstract: An apparatus for anchoring a rod to a bone fastener in a spine stabilization system. A first resilient insert may have two deflectable arms and a first channel formed therein. A second resilient insert may have two deflectable arms and a second channel formed therein. A cylindrical body may have a passage, wherein the first resilient insert and the second resilient insert have a width greater than the inner diameter of the cylindrical body when the first resilient insert is in a neutral state. Advancement of the first resilient insert or the second resilient insert into the passage deflects the two deflectable arms inward, causing the width of the first or second channel to decrease, and inhibiting the first resilient insert or the second resilient insert from moving relative to the cylindrical body.Type: GrantFiled: June 1, 2012Date of Patent: October 7, 2014Assignee: Zimmer Spine, Inc.Inventors: Wesley Hunt, H.

Patent number: 8849439Abstract: A plurality of individual medical devices is created that define a medical device family. Within the family of medical devices, each of the plurality of medical devices has at least one dimension that, within an acceptable tolerance, is substantially equal to the same dimension of another of the plurality of medical devices. Thus, for each medical device in the family, another, corresponding medical device has at least one substantially similar dimension. For example, a first medical device may have a first value for a dimension and a second medical device may have a second value for the same dimension that is equal to one of the sum of the second dimension and the acceptable tolerance or the difference between the second dimension and the acceptable tolerance. Thus, each of the plurality of medical devices varies from another of the plurality of medical devices by the acceptable tolerance.Type: GrantFiled: December 2, 2009Date of Patent: September 30, 2014Assignee: Zimmer, Inc.Inventors: Adam H.

Patent number: 8845749Abstract: A case for modular neck components for hip implants. The case may include indicators based on independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The case allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables. A method described herein may include preoperative planning in which a template including a grid coordinate system is used, which advantageously provides an intuitive system for the surgeon both preoperatively and during surgery.Type: GrantFiled: May 7, 2012Date of Patent: September 30, 2014Assignee: Zimmer, Inc.Inventors: Steven L. Meulink, Ryan D. Schlotterback, Barish Banerjee, Steven J. Vankoski
