A method of performing a surgical procedure includes storing a software application on a memory associated with a computer, which when executed by a processor causes the software application to develop a model of a patient's anatomical structure, process images of the patient's anatomy, display the images of the patient's anatomy on a user interface associated with the computer, superimpose critical structures within the patient over the displayed images of the patient's anatomy, determine a location within the patient's body cavity where the images of the patient's anatomy were taken, and display the model of the patient's anatomical structure on the user interface, the displayed model indicating the determined location where the images of the patient's anatomy were taken.

A method of modeling lungs of a patient includes acquiring computed tomography data of a patient's lungs, storing a software application within a memory associated with a computer, the computer having a processor configured to execute the software application, executing the software application to differentiate tissue located within the patient's lung using the acquired CT data, generate a 3-D model of the patient's lungs based on the acquired CT data and the differentiated tissue, apply a material property to each tissue of the differentiated tissue within the generated 3-D model, generate a mesh of the 3-D model of the patient's lungs, calculate a displacement of the patient's lungs in a collapsed state based on the material property applied to the differentiated tissue and the generated mesh of the generated 3-D model, and display a collapsed lung model of the patient's lungs based on the calculated displacement of the patient's lungs.

Devices, systems, and methods of the present disclosure are directed to generating three-dimensional surface representations of an anatomic structure such as a heart cavity. More specifically, a three-dimensional surface representation of the anatomic structure is constrained relative to one or more anchor portions corresponding to received input regarding the location of anatomic features of the anatomic structure. The resulting three-dimensional surface representation includes salient features of the anatomic structure and, therefore, can be useful as visualization tool during any of various different medical procedures, including, for example, cardiac ablation.

A surgical retractor includes a part defining a longitudinal axis. A first radiolucent blade is connected with the part. A second radiolucent blade is connected with the part. The blades are independently translatable relative to the part. At least one of the blades includes spaced apart arms that are connected via a member. The member and the arms are relatively disposed in a configuration to guide at least one surgical instrument in a selected orientation relative to a surgical site. Surgical systems, instruments, constructs, implants and methods are disclosed.

Methods and system for characterizing ligament properties using elastography are disclosed. An ultrasound system capable of performing shear wave elasticity imaging and/or supersonic shear imaging may retrieve one or more images from a proposed surgical site. The one or more images may be provided to a surgical planning system that identifies one or more properties of ligaments proximate to the surgical site. Musculoskeletal simulations may be performed using the identified properties to preoperatively identify a surgical plan. Preoperative identification of a surgical plan may enable a surgeon to select from more fine-tuning options for a joint replacement than conventional systems.

A method and a system for image-guided intervention such as a percutaneous treatment or diagnosis of a patient may include at least one of a pre-registration method and a re-registration method. The pre-registration method is configured to permit for an efficient virtual representation of a planned trajectory to target tissue during the intervention, for example, as a holographic light ray shown through an augmented reality system. In turn, this allows the operator to align a physical instrument such as a medical probe for the intervention. The re-registration method is configured to adjust for inaccuracy in the virtual representation generated by the pre-registration method, as determined by live imaging of the patient during the intervention. The re-registration method may employ the use of intersectional contour lines to define the target tissue as viewed through the augmented reality system, which permits for an unobstructed view of the target tissue for the intervention.

A method and system of correcting alignment of catheter relative to a target including receiving signals from an inertial measurement unit located at a distal end of a catheter, determining movement of the distal end of the catheter caused by physiological forces, receiving images depicting the distal end of the catheter and the target, identifying the distal end of the catheter and the target in the images, determining an orientation of the distal end of the catheter relative to the target and articulating the distal tip of the catheter in response to the detected movement to achieve and maintain an orientation towards the target such that a tool extended from an opening at the distal end of the catheter would intersect the target.

A method for surgically treating a spine comprising the steps of: pre-operatively imaging vertebral tissue; displaying a first image of a surgical treatment configuration for the vertebral tissue from a mixed reality display and/or a second image of a surgical strategy for implementing the surgical treatment configuration with the vertebral tissue from the mixed reality display; determining a surgical plan for implementing the surgical strategy; and intra-operatively displaying a third image of the surgical plan with the vertebral tissue from the mixed reality display. Systems, spinal constructs, implants and surgical instruments are disclosed.

A system for performing a microwave ablation procedure includes an ablation probe, a tracking system for tracking a position and orientation of the ablation probe, and a computing device. The computing device is configured to receive the position and orientation data of the ablation probe from the tracking system, display a graphical representation of the ablation probe on a display based on the received position and orientation data of the ablation probe, filter axial shift data from the position and orientation data of the ablation probe corresponding to axial movement of the ablation probe along a trajectory axis, and generate an alert based on the filtered axial shift data.

A surgical device controllable by a surgical robotic system is provided. The surgical device includes a housing capable of being coupled to the surgical robotic system; a drive system at least partially mounted in the housing; and a shaft rotatably coupled to the drive system at a first end of the shaft. The surgical device further includes a tissue-removal assembly coupled to the second end of the shaft. The tissue-removal assembly includes a first cutting member having a plurality of rotatable blades. The first cutting member is coupled to a second end of the shaft. The tissue-removal assembly further includes a second cutting member, one or more support elements slidably or fixedly coupled to the second cutting member, and one or more extendable elements slidably or fixedly coupled to the second cutting member.
