An intramedullary fixation device and associated method. The intramedullary fixation device includes a first intramedullary component having a first bone-attachment end and a first elongated member, a second intramedullary component having a second bone-attachment end and a second elongated member, and a compliant member coupling the first and second intramedullary components for applying bone-compressing stress. The second intramedullary component defines a sleeve such that the first elongated member can pass therethrough.
摘要:
A prosthetic system for replacement of a portion of a hip bone including a plurality of acetabular components and a plurality of flange components. The prosthetic system also includes a plurality of pubis components. Each of the pubis components and each of the flange components are operable to connect to each of the acetabular components. Each of the pubis components define a clamping portion that is configured to attach to an opposed healthy pubis bone. An angle between the flange component and the pubis component varies among the acetabular components.

A prosthesis includes an implant defining an attachment surface thereon. A porous insert is selectively coupled to the implant. The porous insert is adapted to be received at the attachment surface of the implant in a retained position. The porous insert is adapted to facilitate tissue ingrowth. In one embodiment the implant comprises a femoral component. The femoral component comprises an inner condylar portion having a first and second lateral sidewalls, an anterior wall and a posterior wall defining a box. The box defines the attachment surface. In other embodiments, the implant comprises a hip stem and an acetabular shell.

A minimally invasive and open surgery surgical system for implanting spinal screw assemblies to be connected by a spinal rod is disclosed. In one form, the system includes an improved tool device for inserting a cap insert into an initial and final locking of a screw assembly and securing a spinal rod inserted through an incision to a vertebra. In another form, the system also includes a screw fixation system that allows greater variability in thread diameter for orthopedic implant for in the spine, iliac crest, or bones.
摘要:
A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force.

A vertical connection apparatus for connecting a pipeline to a subsea structure comprises a guide funnel for controlling the position of the pipeline relative to the subsea structure; a moveable barrier and a attachment region for a drive mechanism; the moveable barrier is operable between an open position in which the pipeline can pass through the guide funnel and a closed position in which the barrier prevent the end of the pipeline passing through the end of the guide funnel. A tool with a drive mechanism can be attached between the pipeline and guide funnel to manipulate the pipeline into a connectable position. A clamp connector secures the connection between the pipeline and subsea structure conduit.

A self-adjusting door closer is disclosed. The door closer is self powered and includes a control unit to intelligently control a valve within the door closer to vary the operating characteristics of the door closer as needed. The controller includes a position sensor to determine a position of the door, and at least one input switch to enable user selection of at least one door closer parameter for an installed door closer. The control circuitry is operable to set the valve in response to the user selection of the door closer parameters, and the position of the door, in order to control force exerted by the door closer on the door. A generator can be provided to provide electricity to power the controller and store power to operate the controller.
