Patent number: 11571246Abstract: A transverse coupling for connecting multiple implant extensions includes at least a first sleeve and a second sleeve. The first sleeve defines a first aperture adapted to axially receive a first implant extension through the first aperture. The second sleeve defines a second aperture adapted to axially receive a second implant extension through the second aperture. The transverse coupling also includes a central housing. A first shaft connects the first sleeve to the central housing, and a second shaft connects the second sleeve to the central housing. The central housing includes at least one joint for connecting the central housing to at least one of the first and second shafts in a movable arrangement that allows the shaft(s) to move through one or more degrees of freedom relative to the central housing.Type: GrantFiled: December 11, 2020Date of Patent: February 7, 2023Assignee: Aesculap Implant Systems, LLCInventors: Jacob Park, Andrew Dauster

Patent number: 9775654Abstract: A surgical ratchet tool and system along with associated methods are disclosed. The surgical ratchet tool can include a relatively simple encompassing member that included a pawl extending into the opening for directly contacting a nut during surgery. The ratchet tool and system can be used for various types of surgery in which easy sterilization and a reduced profile for a ratchet tool is desired. For example, the ratchet tool can be used during surgery for adjustment of a spinal implant, where manipulation of a nut located on a downtube connected to a screw and/or spinal rod is desired. The encompassing member and pawl can be constructed/molded as a single piece unitary structure. A first handle and possibly a second handle can extend from an outer periphery of the encompassing member.Type: GrantFiled: March 15, 2013Date of Patent: October 3, 2017Assignee: AESCULAP IMPLANT SYSTEMS, LLCInventor: Andrew Dauster

Patent number: 9138265Abstract: Apparatuses and methods for inserting elongated fixation elements into screw implants include one or components for visualizing the insertion process from a unique vantage point. One apparatus features a steering apparatus for adjusting the position of a receiver element on a screw implant, so that an elongated fixation element, such as a rod, can be inserted through a transverse passage in the receiver element. The steering apparatus may include an extension tube and a steering control member coupled to the extension tube. The extension tube may be configured for coupling to the receiver element, and the steering control member may be configured for coupling to the extension tube. The steering control member may include an opening for receiving an endoscope. The endoscope may be used to visually monitor the elongated fixation element as it is inserted into the transverse passage of the receiver element.Type: GrantFiled: March 19, 2012Date of Patent: September 22, 2015Assignee: Aesculap Implant Systems, LLCInventors: Andrew Dauster, Anthony R.

Patent number: 9005260Abstract: A receiver body for an elongated spinal fixation element includes a housing portion with one or more flanges extending outwardly. In one embodiment, the receiver body includes first and second flanges extending outwardly from the housing portion. The housing portion includes first and second slots that form a passage through the housing portion. Each flange has a circular perimeter edge and a chamfered section, the chamfered section having a notched undercut for engagement with an instrument. In another embodiment, the receiver body includes a housing portion having a circular flange with a first chamfered section and a second chamfered section diametrically opposite the first chamfered section. The first chamfered section has a first aperture that opens out beneath the flange, and the second chamfered section has a second aperture that opens out beneath the flange. The first and second apertures form diametrically opposed pivot-attachment points for an instrument.Type: GrantFiled: January 15, 2009Date of Patent: April 14, 2015Assignee: Aesculap Implant Systems, LLCInventors: Andrew Dauster, Matthew Kovach, Paul Weaver

Patent number: 8998958Abstract: An instrument includes components configured to secure a locking device inside a rod fixation assembly. In one embodiment, an instrument includes an outer sleeve and a pusher member arranged telescopically within the outer sleeve. A drive assembly cooperatively engages the pusher member. In another embodiment, an instrument includes an outer sleeve, a pusher member arranged telescopically within the outer sleeve, and a pair of drive assemblies. A first drive assembly engages the pusher member to distally advance the pusher member under a first loading. A second drive assembly also engages the pusher member to distally advance the pusher member under a second loading, the second loading being substantially greater than the first loading. In another embodiment, a method for reducing and locking a spinal rod includes the step of advancing a locking element while the locking element is retained in a fixed orientation.Type: GrantFiled: December 20, 2007Date of Patent: April 7, 2015Assignee: Aesculap Implant Systems, LLCInventors: Andrew Dauster, Matthew Kovach, Paul Weaver
