Abstract: Stroboscopic endoscopic systems and related methods employ intermittent energization of one or more light sources to generate a sequence of light flashes. A stroboscopic endoscope system includes an endoscope, an imaging device, a light source, a light transmission assembly, and a controller. The imaging device is configured for imaging an object illuminated via the endoscope. The light transmission assembly is configured to transmit light generated by the light source to the endoscope. The stroboscopic endoscopic systems and related methods employ approaches for increasing the amount of illumination light emitted by the endoscope.

Abstract: A system for assisting a surgeon in placing at least one ablation device into a treatment region of a patient, where the system includes at least one computer system having a display, a user interface and software, is described. The system uses patient image data of the treatment region to generate an image of the treatment region on the display and identifies the treatment region to ablate with a target. Tissue properties of the treatment region are identified and used to perform thermal modeling. Treatment parameters are generated and an ablation zone is calculated. A computer system display is generated showing (a) the number of ablation devices required to ablate the treatment region and the location and orientation of each ablation device in the treatment region and (b) the ablation zone.

Abstract: A sterilant source for use in a portable sterilant system includes a gas-impermeable vial, a frangible ampule containing a first sterilant gas precursor material, disposed within the gas-impermeable vial, a second sterilant gas precursor material, disposed within the gas-impermeable vial and outside the ampule. The first and second sterilant gas precursor materials are selected to be mutually reactive to generate a sterilant gas. The system further includes an activation mechanism, actuatable to break the frangible ampule to release the first sterilant gas precursor material to allow it to react with the second sterilant gas precursor material to generate the sterilant gas.

Abstract: Methods, systems and apparatus for planning the position of a prosthesis in a long bone in orthopaedic surgical procedures, such as hip replacement surgery, knee replacement surgery, long bone osteotomies, and the like. A bone model is generated from a scanned image of a bone, a prosthesis model is selected from a library of prosthesis models and then a cavity model is formed based on the prosthesis model and/or the bone model. The cavity model may then be positioned over the bone model, either interactively by the surgeon or automatically through an algorithm based on clinical parameters, to determine a reasonable location for implantation of a prosthesis within the bone. The cavity model allows the surgeon to optimize placement of the implant within the bone, and it provides important clinical information to the surgeon, such as areas in which press fits are provided, extension areas for possible subsidence and access areas for allowing the surgeon to insert the implant into the cavity.

Abstract: Methods and systems for finish cutting of bone cavities rely on making a plurality of axial finish cuts along the cavity wall. Finish cuts are made using a rotary cutter, and a sufficient number of cuts are made to limit the radial height of cusps between adjacent cuts resulting from the arcuate shape of the cut profile. Cutting time is reduced by selectively terminating the axial lengths of the finish cuts in a manner which does not result in unacceptably high radial cusp heights between adjacent cuts.
