According to an aspect, there is provided an apparatus for use with a treatment device for providing feedback to a user on a treatment operation performed on a body part of a subject, wherein the treatment device is configured to apply light pulses to skin of the body part to perform the treatment operation, wherein a light pulse applied to the skin treats an area of the skin. The apparatus comprises a processing unit configured to receive a first measurement signal from a first sensor, the first measurement signal comprising information about positions and/or movements of the treatment device over time; for a light pulse previously applied by the treatment device to the body part during the treatment operation, process the first measurement signal to estimate a previous treatment position as a position of the treatment device relative to the body part when the light pulse was generated; for the previously applied light pulse and based on the estimated previous treatment position, estimate a previous treatment area for the light pulse corresponding to the area of skin of the body part that the light pulse was applied to when the treatment device was at the previous treatment position; process the first measurement signal to estimate a current position of the treatment device relative to the body part; based on the estimated current position of the treatment device, estimate a current treatment area corresponding to an area of skin that the treatment device would apply a light pulse to while in the current position; and generate a feedback control signal for a feedback unit, wherein the feedback control signal is configured to cause the feedback unit to generate feedback indicating whether the current treatment area corresponds, or substantially corresponds, to a previous treatment area.

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.

Improvements to devices, systems, and methods for delivering and/or deploying an implantable medical device are described. An implantable medical device may include an annuloplasty ring for implantation on a valve of a patient. Systems and methods may be configured to present graphical user interfaces with device images to implement efficient and accurate implantation of the implantable medical device. The device images may be based on sensor information obtained via sensors associated with the implantable medical device, such as a camera device, a diagnostic imaging device, position sensors, and/or the like. In other aspects, systems and methods may determine optimized configurations for the implantable medical device based on device characteristics including, without limitation, a shape formed by components of the implantable medical device and/or component coordinate information. Systems and methods may operate to facilitate deployment of the implantable medical device to correspond with the optimized configuration. Other embodiments are described.

Methods and systems for determining and mapping a location of a distal end region of an elongate shaft. An illustrative method may comprise obtaining data from an accelerometer located in the elongate shaft adjacent a distal end thereof, determining a length of the elongate shaft inserted into a body from a reference point, merging the accelerometer data and the length of the elongate shaft to localize the distal end region of the elongate shaft, reconstructing a line of travel of the medical device within the body, and superimposing the reconstructed line of travel over an image of an anatomy of the patient.

A method for visualizing and targeting anatomical structures inside a patient utilizing a handheld screen device may include grasping the handheld screen device and manipulating a position of the handheld screen device relative to the patient. The handheld screen device may include a camera and a display. The method may also include orienting the camera on the handheld screen device relative to an anatomical feature of the patient by manipulating the position of the handheld screen device relative to the patient, capturing first image data of light reflecting from a surface of the anatomical feature with the camera on the handheld screen device, and comparing the first image data with a pre-operative 3-D image of the patient to determine a location of an anatomical structure located inside the patient and positioned relative to the anatomical feature of the patient.

Systems, methods, and devices are disclosed for end effector identification in robotic surgical systems. A surgical robot can be coupled to an end effector. The system can identify the end effector using data received from the end effector. The system can adjust operation of the surgical system, including the robot arm, based on the data received from the end effector. Data received from or regarding the end effector can include detected characteristics, retrieved characteristics, or data stored on the end effector and communicated to the system. Both the identification and the operation adjustments can be performed automatically such that the system experiences little to no lag or downtime when coupling with different end effectors.

A light system includes a main body defining an internal chamber and a lighting assembly secured to the main body, wherein the lighting assembly comprises at least one light unit configured to emit light. The light system further includes a fan configured to generate an airflow and an airflow circuit configured to direct the airflow out of the main body of the lighting assembly. The light system also includes a tilt detection unit configured to detect a tilt angle of the lighting assembly and to generate a control signal to cause a speed of the airflow generated by the fan to change based at least on a detected change in the tilt angle of the lighting assembly.
