A method for planning the insertion of bone cement into an orthopedic void of a vertebra. A three dimensional preoperative image of the vertebra is used and the voxels are analyzed to provide the voxel absorption levels. The absorption levels are transformed into mechanical properties of regions of the vertebra, such that a three dimensional mesh of the mechanical properties of the vertebra is generated. An entry point and an entry angle are selected on the vertebra, through which to inject bone cement into the void. Then, using the known viscosity of the bone cement, and using the entry point and entry angle, a finite elements analysis may be performed on the mesh to simulate the propagation of the bone cement into the orthopedic void. The simulation is repeated using different operational parameters until said propagation of said bone cement is deemed satisfactory.

A guide for guiding drill bits to form holes in a bone in a predetermined pattern for receiving fasteners to secure an implant to the bone is provided. The guide includes a guide body having a bone interface side opposite an operative side, the bone interface side having a bone contacting surface engageable with a surface of the bone. The guide also includes a plurality of drill guides extending from the operative side of the guide body for guiding corresponding drill bits, wherein the bone contacting surface of the guide body is configured to substantially conform to surface contours of the bone at a predetermined position on the bone. A method of designing the guide is also provided.

An artificial agent based cognitive operating room system and a method thereof providing automated assistance for a surgical procedure are disclosed. Data related to the surgical procedure from multiple data sources is fused based on a current context. The data includes medical images of a patient acquired using one or more medical imaging modalities. Real-time quantification of patient measurements based on the data from the multiple data sources is performed based on the current context. Short-term predictions in the surgical procedure are forecasted based on the current context, the fused data, and the real-time quantification of the patient measurements. Suggestions for next steps in the surgical procedure and relevant information in the fused data are determined based on the current context and the short-term predictions. The suggestions for the next steps and the relevant information in the fused data are presented to an operator.

Methods, apparatuses, and systems for designing, modifying, and installing a surgical implant optimized for a patient's unique physiology are disclosed. The methods are based upon data from surgical implants installed in other patients. Allowing patient outcomes from previously installed surgical implants to influence the design, placement, and surgical tool path for enable the implanting of surgical implants having the greatest likelihood of a successful patient outcome.

Methods for understanding external and internal anatomy of bones through the use of imaging data and 3D modeling to facilitate the design of anatomically correct plates, devices and implants are disclosed. In one aspect the method results in an implant or plate that includes at least one curved surface wherein a contour of the at least one curved surface corresponds to an anatomic shape of a subject. The anatomic shape of the subject being determined based on an image of the bone.

Medical devices may include a patient-engaging section and an instrument-engaging section positioned on a body of the device and the methods of forming such devices. Medical devices described herein may include resection guides, resection guide locators, and/or instruments for use in surgical methods. Devices described herein may have sections that are complementary to a natural anatomical surface of a target area of bone of a predetermined patient. In some instances, a resection guide and resection guide locator may have portions configured to couple the resection guide to the resection guide locator. Resection guides and/or resection guide locators may include openings for receiving an instrument or tool during an operation on the predetermined patient target area of bone.

A method and apparatus that utilizes a force-time integral for real time estimation of steam pop in catheter-based ablation systems. The apparatus measures the force exerted by a contact ablation probe on a target tissue and an energization parameter delivered to the ablation probe. The exerted force and energization parameter can be utilized to provide an estimation of the probability of steam pop. In one embodiment, the force and energization metrics can be used as feedback to establish a desired contact force and energization level combination to prevent steam popping.

A system and method for streamlining inventory and ordering for certain surgical supplies. The method includes scanning, by an imaging device, a surgical site and receiving, by a processor communicatively coupled to the imaging device, data from the scan. The method also includes the processor analyzing the data, where the analyzing includes searching the data to identify predefined key features in the data that are parameters utilized by a Statistical Shape Model (SSM). The processor applies the SSM to generate a three dimensional replica of a predetermined portion of the surgical site. The processor also defines, based on the replica, at last one of: surgical planes or orientations. The processor then utilizes the replica and the surgical planes or orientations to select a solution.
