Devices and methods are described for occluding the left atrial appendage (LAA) to exclude the LAA from blood flow to prevent blood from clotting within the LAA and subsequently embolizing, particularly in patients with atrial fibrillation. An implant is delivered via transcatheter delivery into the LAA. The implant includes a conformable structure comprising a foam body and internal support. The support includes anchors that penetrate the foam body and anchor the implant to the walls of the LAA. The implant provides compliance such that it conforms to the native configuration of the LAA.

The surgeon console includes multiple handles, each communicatively coupled to a robot assembly coupled to a surgical instrument. The surgeon console is configured to transmit to the computing device one or more packets that include data related to a movement of at least one handle. The computing device configured to calculate a new position of the image capture device and transmit instructions to the first robot assembly to move the image capture device to the new position.

An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.

An apparatus includes a processor and a non-transitory memory. The processor is configured to receive pre-operative patient specific data. The pre-operative patient specific data is inputted to a first machine learning model to determine a first predicted post-operative joint performance data output including first predicted post-operative outcome metrics. A reconstruction plan of the joint of the patient is generated based on a medical image of the joint, and at least one arthroplasty surgical parameter obtained from the user. The at least one arthroplasty surgical parameter is inputted into a second machine learning model to determine a second predicted post-operative joint performance data output including second predicted post-operative outcome metrics. The second predicted post-operative joint performance data output is updated to include an arthroplasty surgery recommendation, in response to the user varying the at least one arthroplasty surgical parameter, before the arthroplasty surgery, during the arthroplasty surgery, or both.

A system for electroporation ablation including a catheter having an electrode assembly and one or more states. The electrode assembly may be in different shapes when the catheter is at different states. The controller is configured to generate, based on one or more models of electric fields, graphical representations of electric fields generated by the electrode assembly when the catheter is at different states. In some embodiments, the controller is configured to overlay the graphical representations of the one or more electric fields on an anatomical map of a patient.

A system may be configured to facilitate a medical procedure. Some embodiments may: acquire a scan corresponding to a region of interest (ROI); capture an image of a patient in real-time; identify, via a trained machine learning (ML) model using the acquired scan and the captured image, a Kambin's triangle; and overlay, on the captured image, a representation of the identified Kambin's triangle.

Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

A control system for a surgical robot is provided. The control system includes a first embedded computer and a second embedded computer configured to receive status information from the first embedded computer. The status information includes a status of zero-return for a surgical tool driving module or an imaging tool driving module. The control system also includes a host computer configured to receive the status information from the second embedded computer. The surgical tool driving module or the imaging tool driving module includes a controller, a motor connected with a first coupling and configured to drive the surgical tool or an imaging tool, and a zero point switch configured to detect whether the first coupling is at a zero position. The controller is configured to transmit the status of zero-return to the first embedded computer based on whether the first coupling is at the zero position.

A navigation method for a medical operation and implemented by a robotic system is provided. The method includes the steps of: receiving, at a processor of the robotic system, at least one set of navigation data; receiving or generating at least one three-dimensional model of the virtual object in the navigation data; calculating the navigation data to generate a virtual environment and at least one navigation instruction; and presenting, at a user interface associated with the robotic system, the virtual environment and/or the navigation instruction to a user of the robotic system for the user to refer to during the medical operation.

A method for intraoperatively planning and facilitating a revision arthroplasty procedure. The method includes capturing positions of a tracked probe as the tracked probe contacts an interface area between a bone and a primary implant component implanted on the bone, intraoperatively generating a virtual boundary corresponding to a portion of the interface area to be removed to detach the primary implant component from the bone using the positions of the tracked probe and without use of pre-operative medical imaging, facilitating removal of the primary implant component from the bone by providing a constraint on operation of a cutting tool while the cutting tool removes the portion of the interface area, the constraint based on a relationship between the cutting tool and the virtual boundary.
