Disclosed embodiments determine, at an early stage, suitability of an intraoperative image for further intraoperative surgical analysis. The determination of suitability may be made using a first angle (such as a first obturator angle) based on at least three pelvic feature points in a preoperative image, a corresponding second angle (such as a corresponding second obturator angle) based on at least three corresponding pelvic feature points in an intraoperative image, and by comparing the first angle and the corresponding second angle to determine intraoperative image suitability. The first intra-operative image is indicated as suitable for further intraoperative analysis when an absolute value of a difference between the first angle and the corresponding second angle does not exceed a threshold. When the intraoperative image is determined as unsuitable for further intraoperative analysis, an indication of a movement direction for a fluoroscopy camera used to capture the intraoperative image is provided.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

Provided is a method for forming an implant with an autonomous manufacturing device. The method includes accessing a first computer-readable reconstruction of a being's anatomy; accessing a second computer-readable reconstruction of an implant; accessing a third computer-readable reconstruction comprising the first computer-readable reconstruction superimposed with the second computer readable reconstruction; generating at least one computer-readable trace from a point cloud; and forming an implant with an autonomous manufacturing device, wherein the autonomous manufacturing device forms the implant into a shape defined by at least one dimension of the computer-readable trace.

A method for manufacturing a personalized naturally designed mitral valve prosthesis to precisely fit a specific patient for which the valve prosthesis is made for is provided. The method includes measuring size and shape of a mitral valve of the specific patient by using imaging methods, calculating geometry and dimensions of annular ring, leaflets and chords per the specific patient based on validated algorithms, and cutting and connecting the annular ring, leaflets and chords to form a personalized prosthesis mitral valve.

A method for creating a segmented alignment rod, the method including receiving a request for a segmented alignment rod, receiving at least one image of a deformed spine, generating, a normal spinal curvature, and generating a segmented alignment rod design.

A virtual reality system providing a virtual robotic surgical environment, and methods for using the virtual reality system, are described herein. Within the virtual reality system, various user modes enable different kinds of interactions between a user and the virtual robotic surgical environment. For example, one variation of a method for facilitating navigation of a virtual robotic surgical environment includes displaying a first-person perspective view of the virtual robotic surgical environment from a first vantage point, displaying a first window view of the virtual robotic surgical environment from a second vantage point and displaying a second window view of the virtual robotic surgical environment from a third vantage point. Additionally, in response to a user input associating the first and second window views, a trajectory between the second and third vantage points can be generated sequentially linking the first and second window views.

A conformational state of a medical device operated within a body lumen is determined by measuring, using the medical device as an electrode, an electrical parameter which varies in a correspondence with a conformational state (e.g., deployment state) of the portion of the medical device used as the electrode. The conformational state of the medical device is determined, based on the electrical parameter; and an image is presented indicating the determined conformational state. In some embodiments, the electrical parameter is a self-impedance of the portion of the medical device used as the electrode. In some embodiments, current positioning of the medical device is used as part of calibrating a parametric relationship between the electrical parameter and conformational states of the medical device.

A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.

The present teachings relate to a method for processing a digital dental impression comprising: displaying an image of the digital dental impression; wherein the image comprises: a shaded region representative of a part of the oral anatomy which is relevant for a dental procedure, and the shaded region being enclosed within a boundary; and an unshaded region representative of a part of the oral anatomy which is not relevant for a dental procedure, wherein the unshaded region and the shaded region are separated from each another by the boundary, receiving user input for altering the shaded region and/or unshaded region; detecting completion of a stroke generated by the user input; altering, the shaded region and/or the unshaded region, in response to the stroke completion. The present teachings also relate to a method for processing digital three-dimensional shapes, a dental procedure assisting system, uses and computer software products.

A multi-modal visualization system (MMVS) is provided, which may be used to analyze and visualize bioimaging data, objects, and pointers, such as neuroimaging data, surgical tools, and pointing rods. MMVS can integrate multiple bioimaging modalities to visualize a plurality of bioimaging datasets simultaneously, such as anatomical bioimaging data and functional bioimaging data.
