| 20090036934 | BONE ANCHORING DEVICE - A bone anchoring device includes a bone anchoring element having a shaft for anchoring in the bone and a head; and a receiving part for coupling a rod to the bone anchoring element. The receiving part includes a first portion with a first end and a second end and a U-shaped recess for receiving the rod, the recess extending from the first end in the direction of the second end thereby forming two free legs and a second portion at the side of the second end opposite to the first end for accommodating the head, the second portion having a free end and being flexible so as to allow introduction and clamping of the head. The bone anchoring device also includes a locking ring embracing the second portion. The head is locked by means of exerting pressure with the rod onto the locking ring resulting in compression of the second portion of the receiving part and wherein the locking ring is mounted to the receiving part from the free end of the second portion. | 02-05-2009 |
| 20100042154 | FLEXIBLE STABILIZATION DEVICE INCLUDING A ROD AND TOOL FOR MANUFACTURING THE ROD - A flexible stabilization device for connecting at least two bone anchoring devices which are attached to vertebrae of the spinal column includes a flexible rod made of an elastomer material. The rod has a surface in which at least one recess is provided which is generated by separation of a portion of said elastomer material. | 02-18-2010 |
| 20100042155 | MODULAR SYSTEM FOR THE STABILIZATION OF THE SPINAL COLUMN - A modular system for stabilization the spinal column or other bones includes a first stabilization element, a second stabilization element to be connected to the first stabilization element, and an outer connection element to connect the first stabilization element to the second stabilization element. An end portion of the first stabilization element and an end portion of the second stabilization element each include a structure engaging with a corresponding structure provided in the outer connection element to establish a form-fit connection. | 02-18-2010 |
| 20100087863 | ROD-SHAPED IMPLANT IN PARTICULAR FOR STABILIZING THE SPINAL COLUMN AND STABILIZATION DEVICE INCLUDING SUCH A ROD-SHAPED IMPLANT - A rod-shaped implant for stabilizing bone structures, in particular the spinal column includes a rod-shaped implant having a rod-shaped member with a first end and a second and a longitudinal axis. The rod-shaped member is at least partly made from a plastic material exhibiting flexibility and includes a longitudinal bore. A reinforcing rod is accommodated in the bore and is made from a material which is more rigid than the material of the rod-shaped member itself. The reinforcing rod is slidable in the bore. | 04-08-2010 |
| 20100094348 | BONE ANCHORING ELEMENT AND STABILIZATION DEVICE FOR BONES, IN PARTICULAR FOR THE SPINAL COLUMN - A bone anchoring element includes an anchoring section for anchoring in the bone and a receiving part connected to the anchoring section. The receiving part includes an opening suitable for accommodation of a stabilization rod having a rod axis, the opening being limited along the rod axis by two side walls. The side walls include guides orientated along the rod axis for guiding at least one connection rod therethrough. | 04-15-2010 |
| 20100160975 | RECEIVING PART FOR RECEIVING A ROD FOR COUPLING THE ROD TO A BONE ANCHORING ELEMENT AND A BONE ANCHORING DEVICE WITH SUCH A RECEIVING PART - A receiving part for receiving a rod for coupling the rod to a bone anchoring element includes a receiving part body including a rod receiving portion with a channel for receiving a rod, and a head receiving portion for accommodating a head of a bone anchoring element, the head receiving portion having an open end and being flexible so as to allow introduction and clamping of the head, the head receiving portion having an exterior surface with a tapered portion; and a locking ring around the head receiving portion and including an interior surface with a curved portion configured to engage the tapered portion of the exterior surface of the head receiving portion to clamp the head. | 06-24-2010 |
| 20100160976 | RECEIVING PART FOR RECEIVING A ROD FOR COUPLING THE ROD TO A BONE ANCHORING ELEMENT AND A BONE ANCHORING DEVICE WITH SUCH A RECEIVING PART - A receiving part for receiving a rod for coupling the rod to a bone anchoring element, the receiving part including: a receiving part body including a rod receiving portion with a channel for receiving a rod, and a head receiving portion for accommodating a head of a bone anchoring element, the head receiving portion having an open end and being flexible for inserting and clamping of the head; a locking ring around the head receiving portion to exert a first force onto the head receiving portion to lock the head therein; and a pre-locking ring separate from the locking ring and around the head receiving portion to exert a second force less than the first force onto the head receiving portion to clamp the head in a temporary pre-locking position. | 06-24-2010 |
| 20100168800 | RECEIVING PART FOR RECEIVING A ROD FOR COUPLING THE ROD TO A BONE ANCHORING ELEMENT AND A BONE ANCHORING DEVICE WITH SUCH A RECEIVING PART - A receiving part for coupling a rod to a bone anchoring element includes a receiving part body including a rod receiving portion having a channel for receiving a rod, and a head receiving portion for accommodating a head of a bone anchoring element, the head receiving portion having an open end and being flexible for inserting and clamping of the head; and a locking ring around the head receiving portion, wherein in a pre-locking position, a spring portion on one of the locking ring or the receiving part body engages a corresponding portion on the other one of the locking ring or the receiving part body, and the locking ring exerts a first force onto the head receiving portion, and wherein in a locking position, the locking ring exerts a second force greater than the first force onto the head receiving portion to lock the head therein. | 07-01-2010 |
| 20100168801 | RECEIVING PART FOR RECEIVING A ROD FOR COUPLING THE ROD TO A BONE ANCHORING ELEMENT AND BONE ANCHORING DEVICE WITH SUCH A RECEIVING PART - A receiving part for receiving a rod for coupling the rod to a bone anchoring element includes a receiving part body including: a rod receiving portion with a channel for receiving a rod, and a head receiving portion for accommodating a head of a bone anchoring element, the head receiving portion having an open end and being flexible for inserting and clamping of the head, and an exterior surface with a curved portion; and a locking ring around the head receiving portion, wherein the locking ring has an interior surface with a curved portion for engagement with the curved portion of the exterior surface of the head receiving portion for locking a position of the head relative to the head receiving portion. | 07-01-2010 |
