Selectively Expanding Spine Cage, Hydraulically Controllable In Three Dimensions for Vertebral Body Replacement

Номер: US20120116518A1
Автор: Rudy Pretti, Thomas Grotz
Принадлежит: Coalign Innovations Inc

A selectively expanding spine cage has a minimized diameter in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of vertebrae to effectively distract the anterior disc space, stabilize the motion segments, eliminate pathologic spine motion, or effect vertebral body replacement. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

The valve stent comprises a stent body, a positioning ring and elastic connection wires, wherein the positioning ring in a compressed state is adapted to be arranged in series with the stent body sequentially along an axis thereof, and when the positioning ring has elastically deformed from the compressed state to a propped open state, the positioning ring becomes coaxially sleeved on the stent body due to traction of the elastic connection wire. In the valve stent of the present application, after being implanted, the positioning ring can automatically expand to reach the propped open state by elastic deformation, and due to the traction of the elastic connection wire, the positioning ring can become coaxially sleeved on the stent body. Therefore, in the process of an implanting surgery, the positioning ring and the stent body can be positioned at the same time. Due to the traction of the connection wire, the stent body can be automatically positioned according to the location of the positioning ring, so that respective positioning operations of the positioning ring and the stent body are dispensed with, and the surgery operation can be made simple and convenient. 1. A valve stent , comprising{'b': 1', '9, 'a stent body (), having a ring structure that can be radially propped open, and adapted to accommodate a prosthetic valve leaflet () in an interior thereof;'}{'b': 6', '1, 'a positioning ring (), having a radially compressible ring structure, and adapted to accommodate the stent body () in an interior thereof; and'}{'b': 5', '6', '1, 'an elastic connection wire (), with one end fixedly connected to an upper end of the positioning ring (), and with the other end fixedly connected to a middle or lower part of the stent body ();'}wherein{'b': 6', '1, 'the positioning ring () in a compressed state is adapted to be arranged in ...

The present foot prosthesis includes various structural features that provide the foot with advantageous rollover properties. In certain embodiments, the foot guides rollover toward the medial side. For example, an asymmetrical upper element and a correspondingly shaped resilient ankle member support more of the wearer's weight on the lateral side as the foot rolls over. In another embodiment, stiffeners added to the resilient ankle member increase the stiffness on the lateral side relative to the medial side. In certain other embodiments, the foot provides progressively increasing support from mid stance through toe off.

Selectively expanding spine cage with enhanced bone graft infusion

Номер: US20180064557A1
Автор: Damien J. Shulock, John E. Ashley, Rudy Pretti, Thomas Grotz
Принадлежит: Howmedica Osteonics Corp

A selectively expanding spine cage has a minimized cross section in its unexpanded state that is smaller than the diameter of the neuroforamen through which it passes in the distracted spine. The cage conformably engages between the endplates of the adjacent vertebrae to effectively distract the anterior disc space, stabilize the motion segments and eliminate pathologic spine motion. Expanding selectively (anteriorly, along the vertical axis of the spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces in natural lordosis. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage shape intends to rest proximate to the anterior column cortices securing the desired spread and fixation, allowing for bone graft in, around, and through the implant for arthrodesis whereas for arthroplasty it fixes to endpoints but cushions the spine naturally.

No. 11/615,077, filed Dec. 22, 2006, the disclosure of each of which is incorporated herein by reference.The natural intervertebral disc contains a jelly-like nucleus pulposus surrounded by a fibrous annulus fibrosus. Under an axial load, the nucleus pulposus compresses and radially transfers that load to the annulus fibrosus. The laminated nature of the annulus fibrosus provides it with a high tensile strength and so allows it to expand radially in response to this transferred load.In a healthy intervertebral disc, cells within the nucleus pulposus produce an extracellular matrix (ECM) containing a high percentage of proteoglycans. These proteoglycans contain sulfated functional groups that retain water, thereby providing the nucleus pulposus with its cushioning qualities. These nucleus pulposus cells may also secrete small amounts of cytokines as well as matrix metalloproteinases (MMPs). These cytokines and MMPs help regulate the metabolism of the nucleus pulposus cells.In some instances of degenerative disc disease (DDD), gradual degeneration of the intervertebral disc is caused by mechanical ...
