Patent number: 8721692Abstract: Minimally invasive methods and devices are provided for positioning a spinal fixation element in relation to adjacent spinal anchors. In an exemplary embodiment, the device is a percutaneous access device that can be coupled to a spinal anchor, and the method includes the step of positioning a spinal fixation element through at least one sidewall opening of at least two percutaneous access devices such that the spinal fixation element extends in a lengthwise orientation that is substantially transverse to the longitudinal axis of each percutaneous access device. The spinal fixation element can then be advanced in the lengthwise orientation to seat the spinal fixation element in or adjacent to the receiver heads of at least two adjacent spinal anchors. A fastening element or other closure mechanism can then be applied to each spinal anchor to engage the spinal fixation element within the receiver heads of the adjacent anchors.Type: GrantFiled: August 2, 2013Date of Patent: May 13, 2014Assignee: DePuy Synthes Products LLCInventors: David Greg Anderson, George Joseph Ross

Patent number: 8444676Abstract: A spinal anchor assembly for securing a spinal fixation element has an anchor element adapted for attachment to bone. The anchor element has an opening for receiving a spinal fixation element and side walls on opposed sides of the opening with a plurality of inferior surfaces defined on the side walls. A twist-lock closure closes the opening and captures the spinal fixation element. A locking element can be provided on the closure element and the anchor element. The locking element can be configured so that when the closure element is rotated from the open position to the closed position, the locking element engages to deter the closure element from twisting back to the open position.Type: GrantFiled: June 2, 2006Date of Patent: May 21, 2013Assignee: DePuy Spine, Inc.Inventors: Frank Scott Bono, George Joseph Ross, Christopher W.

Publication number: 20120078316Abstract: Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patient's spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.Type: ApplicationFiled: December 2, 2011Publication date: March 29, 2012Applicant: DEPUY SPINE, INC.Inventors: David Greg Anderson, Christopher W.

Patent number: 7125426Abstract: A spinal anchor assembly for securing a fixation element includes an anchor element and a twist-in cap. The anchor element is configured for attachment to a bone, typically by comprising a mono- or polyaxial screw or hook, and includes a proximal portion having an open slot for receiving the fixation element and having radially inwardly protruding flange segments. The twist-in cap is received in and closes the open slot. The proximal portion of the anchor and the cap are adapted to twist-lock together by a partial rotation of the cap from an open position to a closed position to cover the slot so as to capture the fixation element and to lock the cap in the closed position.Type: GrantFiled: June 25, 2003Date of Patent: October 24, 2006Assignee: DePuy Spine SARLInventors: Missoum Moumene, Ian Burgess, George Joseph Ross, Christopher Sicvol, Frank Bono

Patent number: 7081117Abstract: An assembly such as an anchor screw, bone plate, offset hook, post, transverse connector or other spinal anchor for anchoring to bone and clamping a linkage such as a rod, wire cable or the like. The assembly has a top member with an open slot to receive the linkage, and a twist-lock closure cap to close the open end, capturing the linkage in the slot. One closure cap fits over and around the top member, with a set of segmented protrusions that extend through a corresponding set of protruding flange segments spaced about the circumference of the top member. The cap is configured to rotate and lock against the top member like a flange-locking bayonet mount when turned through a limited degree of rotation.Type: GrantFiled: April 20, 2004Date of Patent: July 25, 2006Assignee: DePuy Acromed, Inc.Inventors: Frank Scott Bono, George Joseph Ross, Christopher Werner Sicvol, Ian Burgess
