System for training an interventionalist to perform an invasive percutaneous or endoscopic intervention on an organ includes a pipe having a size and/or shape similar to a body vessel or tubular body cavity connected to the organ. An exit of the pipe simulates or represents an exit of the vessel or cavity at the organ. A tool is inserted at an entrance of the pipe and pushed through the pipe. A stereoscopic camera acquires images of an end portion of the tool as it exits from the pipe. A model generating unit generates a real-time 3D model of this end portion from the images. A merging unit merges in real time the real-time model and a pre-computed 3D model of the organ into a common environment displayed so that the interventionalist can see in real-time where the real-time model of the tool is located with respect to the pre-computed model.

A rotary tool includes a tool body and a powered rotary cutting tooltip that is oriented and positioned relative to the tool body by a plurality of processor-controlled actuators that provide degrees of freedom. The processor uses a surgical tracking system to identify the pose of the tool body and the tooltip relative to a patient's anatomy and controls the actuators to maintain the tooltip within a predetermined cutting plan to compensate for deviation of a surgeon's hand or a robotic arm controlling the tool body during a cutting operation.

A tibial tray system for a resurfaced proximal portion of a tibia for a knee replacement for a patient includes a tibial tray and at least one screw. The tibial tray includes a body having a superior portion, and an inferior tibia-engaging portion having a peripheral inferiorly-extending portion receivable in the at least one cavity formed in the periphery of the resected cancellous bone surface of the tibia of the patient. In some embodiments in the total knee replacement, a greater portion of a shearing force acting transversely on the tibial tray and the resected portion of the proximal portion of the tibia of the patient is resisted by the at least one inferiorly-extending wall compared to a portion of the shearing force being resisted along the center inferior surface of the tibial tray and the resected cancellous bone surface. The screw inhibits lift-off.

The invention provides for a system for estimating a 3-dimensional treatment volume for a device that applies treatment energy through a plurality of electrodes defining a treatment area, the system comprising a memory, a display device, a processor coupled to the memory and the display device, and a treatment planning module stored in the memory and executable by the processor. In one embodiment, the treatment planning module is adapted to generate an estimated first 3-dimensional treatment volume for display in the display device based on the ratio of a maximum conductivity of the treatment area to a baseline conductivity of the treatment area. The invention also provides for a method for estimating 3-dimensional treatment volume, the steps of which are executable through the processor. In embodiments, the system and method are based on a numerical model which may be implemented in computer readable code which is executable through a processor.

A method for analyzing a real dental situation of a patient. The method includes steps, as follows, in succession. At an updated instant, acquisition of an updated image representing a real dental scene as observed by an operator. Determination of a virtual dental scene as a function of the representation of the real dental scene on the updated image. Presentation of the virtual dental scene in transparent mode and overlaid on the real dental scene, or display of the updated image on a screen and presentation of the virtual dental scene overlaid with the representation of the real dental scene on the updated image displayed on the screen, in transparent mode or not on the representation.

A method of treating one of fractures and disfunctions of a pelvic ring of a patient comprising scanning a patient with a transdermal scan, determining, via a machine, from the scan an optimal range of angles of entry and sizes of screw to insert into the patient, communicating the optimal range to a surgeon, and inserting the screw into the patient.

Methods, systems, devices, assemblies and apparatuses for treatment of hypertension in a patient using renal denervation. The therapeutic assembly includes an energy delivery element. The energy delivery element is configured to provide renal denervation energy to a nerve within a blood vessel of a patient. The therapeutic assembly includes a controller. The controller is coupled to the energy delivery element. The controller is configured to determine that the hypertension in the patient is orthostatic. The controller is configured to apply renal denervation energy to the patient using the energy delivery element.

This disclosure describes manufacturing of a device configured to guide bone and tissue regeneration for a bone defect. A method may include receiving a three-dimensional digital model or scan representing an anatomical feature to be repaired, generating a simulated membrane using the three-dimensional model, the simulated membrane being configured to cover the anatomical feature to be repaired, generating a digital two-dimensional flattened version of the simulated membrane, and generating code or instructions configured to cause a three-dimensional printer or milling device to produce a trimming guide that includes an opening corresponding to the flattened version of the simulated membrane and that further includes a cut-out configured to hold a premanufactured membrane. The trimming guide may be operative as a guide for marking or cutting the premanufactured membrane through the opening while the premanufactured membrane is held in the cut-out.

A device for simulating a surgical activity may present a first graphical representation of a portion of anatomy. The device may simulate a path for the surgical activity. The device may determine surgical tool selection points associated with selecting surgical tools on the path for the surgical activity. The device may present a surgical range to select from at surgical tool selection points. In response to receiving an indication of the selected surgical range, the device may simulate a surgical outcome associated with selecting a surgical tool at the surgical tool selection point. In response to receiving an indication of the selected surgical tool, the device may generate the selected surgical tool at the surgical tool selection point.

A computer-implemented method for determining implant positions of two implant components relative to two bones that form a joint is disclosed. The method includes acquiring a set of target poses to be achieved between the two bones, assessing one or more proposed implant arrangements using the set of target poses, and selecting an implant arrangement from the proposed implant arrangements based on the assessment. Assessing an implant arrangement includes determining a real pose between the two bones for each target pose, calculating a pose deviation value for each target pose based on the target pose and the corresponding real pose, and calculating an overall pose deviation value from the individual pose deviation values. The implant arrangement may be selected based on the overall pose deviation values for the proposed implant arrangements.
