20080269742 | CONNECTOR ASSEMBLY FOR BONE ANCHORING ELEMENT - A connector assembly including a bone anchoring element, an articulating interface element including a bone-anchoring-element interface portion extending from a connecting-element interface portion, the bone-anchoring-element interface portion including a plurality of resilient fingers adapted to resiliently clamp on the bone anchoring element, and wherein the connecting-element interface portion includes a pair of arms that define a channel for receiving therein a connector element, and a cap member that fastens on to the arms, wherein tightening of the cap member against the arms causes squeezing of the fingers to clamp them on the bone anchoring element. | 10-30-2008 |
20090024217 | EXPANDABLE BONE DEVICE - An expandable bone device including first and second bone support elements, a manipulator positioned between the first and second bone support elements and connected to them by link members, the manipulator adapted to move the first and second bone support elements between a collapsed orientation and an expanded orientation, wherein in the collapsed orientation the first and second bone support elements are drawn towards the manipulator and in the expanded orientation the first and second bone support elements are moved outwards away from a longitudinal axis of the manipulator, and deformable support struts connected between the manipulator and the first and second bone support elements that deform when moved by the manipulator from the collapsed orientation to the expanded orientation and vice versa, wherein in the expanded orientation the deformable support struts form a structure that maintains the first and second bone support elements in the expanded orientation. | 01-22-2009 |
20090143827 | DOUBLE COLLET CONNECTOR ASSEMBLY FOR BONE ANCHORING ELEMENT - A connector assembly including a bone anchoring element including a spherical head, a double collet that includes an inner clamping portion formed by inner surfaces of a plurality of resilient fingers, the resilient fingers defining a first wedge surface and a second wedge surface, an outer closure element that includes an inner clamping portion that corresponds in shape to an outer contour of the double collet, the outer closure element including a pair of arms that define a channel shaped for receiving therein a connector element, and an interface ring that includes a base formed with an inner wedge surface and a pair of wing extensions that extend from the base. | 06-04-2009 |
20090210007 | CROSS-CONNECTOR ASSEMBLY - An assembly including a connector element including a receptacle from which extends a neck, a lug element sized to fit in the receptacle of the connector element, ears pivotally connected to the lug element, and a mechanical fastener that fastens the connector element together with the lug element, thereby causing the ears to pivot and grip a connector rod placed between the ears. | 08-20-2009 |
20110319946 | BONE IMPLANTATION AND STABILIZATION ASSEMBLY INCLUDING DEPLOYMENT DEVICE - The present disclosure provides for improved bone implantation and stabilization assemblies, and improved systems/methods for deploying and/or undeploying such bone implantation and stabilization assemblies. More particularly, the present disclosure provides for improved devices, systems and methods for stabilizing bones and/or bone segments. In exemplary embodiments, the present disclosure provides for improved devices, systems and methods for deploying bone implantation and stabilization assemblies into bone tissue (e g., spinal structure, vertebrae, cancellous bone, cortical bone, etc.) in order to stabilize bones and/or bone segments. | 12-29-2011 |
20120165880 | BONE FRACTURE TREATMENT DEVICES AND METHODS OF THEIR USE - The present disclosure provides for improved devices, systems and methods for stabilizing bones and/or bone segments that have become displaced and/or unstable due to fractures. In exemplary embodiments, the present disclosure provides for improved devices, systems and methods for deploying bone anchoring elements into bone tissue in order to stabilize bones and/or bone segments that have become displaced and/or unstable due to fractures or the like. In one embodiment, a bone treatment assembly includes a shaft configured to extend at least partially into bone tissue. The shaft includes at least one bone anchoring element with a tissue-piercing portion that is selectively displaced or deployed to engage bone tissue. The at least one bone anchoring element may be displaced by one or both of an inner member sized to extend into a lumen in the shaft and/or an outer member that is translatable over the shaft. | 06-28-2012 |
