Devices and systems can be used to treating spinal conditions. For example, this document describes artificial facet joint systems that can be implanted to treat spinal conditions while facilitating normal stability and motions of the spine. Such systems and methods can be used to treat spinal conditions such as, but not limited to, spondylosis, vertebral fractures, and the like.

An implant (1) for modifying the tissue deformation during bone healing between two bone fragments (5; 6), with a first end piece (2) that can be fastened to a first bone fragment (5) with a longitudinal axis L1, and a second end piece (3) that can be fastened to a second bone fragment (6) with a longitudinal axis L2, wherein the first and second end pieces (2; 3) are loosely meshed with one another by means of n1 parallel-connected tissue activators (4a; 4b) in each case to allow relative movement and the tissue activators (4a; 4b) are arranged to be perpendicular to the longitudinal axes L1 and L2 and preferably orthogonal thereto.

Fired magnesium oxide stabilized zirconia ceramic body having a highly smooth, polished or otherwise equivalent surface has, on at least part of the surface, a metal/metal alloy coating. The fired ceramic body can be a magnesium oxide stabilized tetragonally toughened zirconia. The coating can be from a metal or metal alloy other than by tantalum vapor deposition, and can include a titanium metal or alloy. The coating can be a macro coating, up to less than about 0.015 of an inch in thickness. The coated magnesium oxide stabilized zirconia ceramic can be a tool or an orthopedic implant or component for an orthopedic implant, which can be a load bearing implant or component for a load bearing implant having an articular surface and a nonarticular surface where the metal or metal alloy coating is on at least part of the nonarticular surface. Plasma arc spraying under vacuum may be employed.

Technologies are generally provided for devices, systems, and methods to provide spinal fixation, spinal stabilization, and/or spinal fusion. Example devices may include a first end and a second end with a middle portion extending between the first and second end. The first end may be configured to be in contact with a portion of a first or upper vertebra and the second end may be configured to be in contact with a portion of a second or lower vertebra in an adjacent vertebral pair. Portions of the vertebra which may be in contact with the device may include lamina, processes, vertebral bodies, and facet joints. The example devices may include bone engagement features, such as screws or similar fasteners, to enhance stabilization and fixation when in contact with the vertebrae. Additionally, the devices may include a bone integration feature to promote bone growth and to facilitate fusion between the vertebrae.

A device (1) with a stent structure (2) wherein the stent structure (2), preferably at its proximal end, is connected to an insertion aid (3), and wherein the device (1) is deployable for the treatment of a vasospasm and the stent structure (2) is designed so as to be detachable from the insertion aid (3), with at least portions of the stent structure (2) being provided with a coating and this coating comprising a functional layer, with said functional layer containing at least one sugar alcohol and/or being formed by an oligo- or polymerization of monosaccharides functionalized with polymerizable groups. Furthermore, the invention also relates to a relevant method for the treatment of vasospasms.

Devices, systems and methods for surgical treatment of mid-foot disorders such as osteoarthritis, spacing disorders, or alignment disorders, including mid-foot arthroplasty devices and systems for the 2.sup.nd and 3.sup.rd tarsometatarsal (TMT) joint, implants for post-osteotomy spacing and realignment, arthroplasty articular implants, dowel grafts for TMT arthrodesis or fusion, dowel grafts for navicular cuneiform (NC) arthrodesis, dowel grafts for intercuneiform arthrodesis, and/or locking dowels for joint fusion.

An orthopedic implant which generally includes a frame structure and a porous structure. Both the frame and porous structure at least partially define at least six surfaces which make a three-dimensional profile of the implant. The porous structure is positioned at least partially within the three-dimensional profile.

A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site is provided. The system includes a manifold delivery tube and a balloon having an inner space. The balloon is capable of assuming collapsed and expanded positions. The system further includes a manifold having a plurality of flow channels. The manifold is disposed within the inner space of the balloon. A sharp tip is configured to be delivered within the manifold delivery tube to puncture the balloon.

A metal balloon catheter having a main tubular body, a metal balloon proximate a distal end of the main tubular body, a central annulus extending along an entire longitudinal aspect of the catheter for accommodating a guidewire therethrough and an inflation annulus adjacent the central annulus which extends along the longitudinal axis of the main tubular body and terminates in fluid flow communication with an inflation chamber of the metal balloon. The metal balloon catheter may be either unitary integral metal catheter in which the main tubular body and the balloon are fabricated of metal, or it may consist of a polymeric main tubular body and a metal balloon.

A modular acetabular cup assembly for use with multiple bearing liners is disclosed. The acetabular cup assembly includes a shell having a tapered inner wall and two circumferential grooves. The shell may be used with polyethylene, ceramic, metal, and other types of liners.
