SACROILIAC JOINT FUSION SYSTEMS AND METHODS
A sacroiliac joint implant is formed from a web structure having a space truss with two or more planar truss units having a plurality of struts joined at nodes. The web structure is configured for fusion of a sacroiliac joint.
SUPPORTING MEMBER AND SUPPORTING MEMBER ASSEMBLY FOR IMPLANTATION INTO OR BETWEEN SUBJECTS BONES, AND TEMPLATE PLUG AND TAMPER CORRESPONDING TO THE SAME
The present invention provides a supporting member and a supporting member assembly including the same to be implanted into or between a subject's bones, and a template plug and a tamper corresponding to the supporting member. The supporting member comprises a main body; a first connecting portion and a second connecting portion formed on the upper and lower sides of the main body respectively and forming a dovetail joint with each other; and a guiding structure formed at a side of the main body and including guiding holes as well as a buffer groove for mating with an external template plug. The supporting members of the invention can be sequentially implanted and connected into a bone or between two connected bones, and improve the defect of the conventional one-size giant implants injuring the surrounding nerves.
BIOCOMPATIBLE MEDICAL DEVICE AND METHOD OF MAKING SAME
The present invention relates generally to biocompatible medical devices, such as cranial implants, and a method and means of attaching to hone. More specifically, the present invention relates to multilayered porous material with controlled porosity and drug load designed to control the release of drugs from a medical device. Additionally the present invention provides methods for controlling release of drugs by integrating the multilayer structure in medical devices with successive layers of polymer coatings of different porosities and drug contents. The multilayer material is inserted in between two plates such as meshes that provide strength to the implant. The present invention relates to biocompatible medical devices that has osseointegration and antibacterial properties. The present invention also relates to a method and means of attaching the medical device to defect in a bone structure and comprises of tree mounting parts configured to secure the medical in place.
Expandable interbody fusion device
An expandable interbody fusion device includes superior and inferior endplates that are configured to receive a sequentially inserted stack of interlocking expansion members or wafers. The like-configured wafers include features on their top and bottom surfaces that interlock the wafers in multiple degrees of freedom so that the wafer stack is not disrupted when the fusion device is fully expanded. One of the interlocking features includes a plurality of prongs projecting from an upper surface of the wafers and into a recess defined in the lower surface of an adjacent previously inserted like-configured wafer. The prongs and recesses are configured to prevent retrograde movement of each new wafer in a direction opposite the direction of insertion. Other interlocking features prevent movement in the direction of insertion, transverse to the insertion direction and vertically within the stack.
Graft collection and containment system for bone defects
A device for containing bone graft material comprises a body including an inner sleeve extending longitudinally from a proximal end to a distal end and an outer sleeve surrounding the inner sleeve and extending longitudinally from a proximal end to a distal end such that a bone graft collecting space is formed therebetween.
MULTI-PIECE INTERVERTEBRAL IMPLANTS
Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.
RECONSTRUCTION PROSTHESIS
The disclosure relates to a reconstruction prosthesis including a plurality of prosthesis units connected in series. Each of the prosthesis units includes a main part and a cushion structure. The main part has an abutment insertion opening and an accommodation space. The cushion structure is located in the accommodation space and movably located at the abutment insertion opening and defining an abutment mounting hole connected to the abutment insertion opening. The cushion structure is deformable with respect to the main part.
Articulating knee spacer and method of manufacture
A joint implant for temporary or permanent use has a femoral component and tibial component. The femoral component has a base and rod extending therefrom and defines a pin. The tibial component has a base and rod extending therefrom and defines a bore in which the pin is seated so that the femoral component is rotatable relative to the tibial component.
ORTHOPAEDIC IMPLANT WITH POROUS STRUCTURAL MEMBER
A tool for use with an orthopaedic implant includes: a tubular assembly including a tubular passage having a first end and a second end, the first end including a means for attachment to an implant body; a plug; and a plunger coupled to the plug. The tubular passage is configured to receive, via the second end, a material agent and the plunger coupled to the plug. The plunger is configured to slide through the tubular passage for expelling the material agent from the tubular passage into a load bearing member via the at least one first opening. The plunger is configured to rotate within the tubular passage for coupling the plug with the first opening to seal the first opening against expulsion of the material agent from the load bearing member via the first opening.
Multi-piece intervertebral implants
Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.
