Abstract: The invention is a total knee endoprosthesis with a fixed flexion-extension xis throughout all degrees of flexion and extension of the knee. The endoprosthesis has a femoral component with spaced apart medial and lateral condyle portions which slidably seat on a tibial implant portion. The fixed flexion-extension axis is directed inferiorly and posteriorly from the medial condyle portion to the lateral condyle portion and is offset from both the transverse and coronal planes equally by 3.0 to 3.8 degrees. A longitudinal axis through the tibia allows the tibia to rotate nonorthogonally and anteriorly of the flexion-extension axis. A patellar groove which is perpendicular to the flexion-extension axis. In the patellar groove slides an optional patellar component or the natural patella.

Abstract: A method for the diagnosis and treatment of infertile women, utilizing norgical, transcervical uterine lavage to recover ova for the purpose of analysis, morphologic assessment, and treatment.

Abstract: A device for enabling substantially-anatomic reduction of a posteriorly uable pelvic disruption, as of a fracture or dislocation of the posterior pelvis. The device is adapted to enable secure fixation thereof to the posterior pelvic disruption. It is further adapted to enable fine adjustment of the alignment and fit of the disrupted surfaces, operable from a position externally of the patient's body, and to retain the united positions of the disrupted surfaces, for substantially-anatomically reducing the posteriorly unstable pelvic disruption. The device includes a plurality of tapper threaded pins, each adapted to be tapped into the outer cortices of the posterior pelvic bone at a location proximate the site of the posterior pelvic disruption. The device further includes a frame, adapted to enable the tapper threaded pins to be connected thereto for interconnection thereof, and mechanisms adapted to enable externally operable fine adjustment of the frame in a plurality of planes.

Abstract: A method and apparatus for the controlled simulation of respiratory gas exchange as it takes place in mammals, for the primary purpose of calibrating and checking the performance of laboratory and clinical test equipment systems. The method and apparatus can reproduce any range of respiratory performance by pumping and mixing atmospheric air with a gas mixture of carbon dioxide and nitrogen. This invention provides an accurate, economical and rapid apparatus for on-line calibration of analytical respiratory test systems.

Abstract: This invention relates a simplified and reliable process for the detection and measurement of viral specific immunoglobulins such as IgG, IgM and IgE wherein relatively large-diameter plastic beads, e.g., 1/4", diameter polystyrene balls with a specular finish, are used as the solid matrix upon which a high concentration of standard cells are first grown or cultured. The cells are then infected with a particular virus to express a high concentration of unpurified viral antigen(s), and are then fixed to preserve the viral antigen(s) concentration. The resulting fixed plastic beads (PB) are washed (to remove fixing agent) and then employed as the basis of the detection of specific immunoglobulins in the patient's serum. The detection process involves simply incubating a measured dilution of patient serum with each PB whereby the various specific immunoglobulins in the patient serum will attach to the viral antigen(s) on the PB. The specific immunoglobulins (e.g.
