A system for aiding surgery on a patient is described including a display device and a storage device that stores an image of at least a portion of the anatomy of the patient, including one or more surgical navigation markers positioned on the patient, for display on the display device. An analyser is adapted to receive positional data of a probe based on positioning of the probe relative to the one or more markers on the patient. Based on the positional data, the analyser outputs correctional data to adjust an alignment of the image on the display device to match locations of said one or more markers.

A system and method for providing image guidance for placement of one or more medical devices at a target location. The system can determine one or more intersections between a medical device and an image region based at least in part on first emplacement data and second emplacement data. Using the determined intersections, the system can cause one or more displays to display perspective views of image guidance cues, including an intersection indicator in a virtual 3D space.

A method for displaying guidance information using a graphical user interface during an medical procedure comprises displaying, in a first mode of the graphical user interface, first image data from a perspective corresponding to a distal end of an elongate device. The first image data includes a virtual roadmap. The method also comprises transitioning from the first mode of the graphical user interface to a second mode of the graphical user interface. The transition is based on an occurrence of a triggering condition. The method also comprises displaying, in the second mode of the graphical user interface, second image data from a perspective corresponding to the distal end of the elongate device. The second image data includes a target indicator corresponding to a target location and an alignment indicator corresponding to an expected location of the medical procedure at the target location.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

Systems and methods for camera control within surgical robotic systems are provided. One system includes a computing device, multiple robot assemblies, and a surgeon console. Each robot assembly among the multiple robot assemblies includes a robotic arm. A robotic arm of a first robot assembly is coupled to an image capture device. Robotic arms of at least a subset of robot assemblies, different from the first robot assembly, are coupled to surgical instruments. 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.

The present disclosure discusses a devices, systems and methods for transvascular, transvenous and/or transdural access, to the brain parenchyma, subarachnoid or subdural spaces. In some embodiments, the disclosed systems and methods may be used for local drug delivery, tissue biopsy, nanofluidic or microelectronic device/component delivery/insertion/implantation, in situ imaging, ablation of abnormal brain tissue and the like. Embodiments of the present disclosure include an access catheter system for extravascular procedures in the brain having an elongate, flexible tubular body, with at least one lumen extending axially there through between a proximal end, and a distal end. The access catheter system may include a side exit port and a distal end port. Further, the access catheter system may include a selective deflector positioned within the lumen configured to deflect a procedure catheter and permit a guide catheter.

A system and method are presented for treating targeted tissue using cryoablation. An introducer canula and a cryoprobe are inserted the targeted tissue. The cryoprobe is cooled and an ice ball is formed. The cryoprobe is removed while the ice ball is still frozen, and an ultrasound catheter is inserted. Ultrasound generated within the ice ball is used to determine the distance from the ultrasound catheter to a perimeter of the ice ball. This is repeated at different angles to model a slice of the ice ball. The ultrasound catheter is moved radially, and the process is repeated to create a model of at least a portion of the ice ball. The ice ball model can be displayed on a registered set of images representing the targeted tissue to ensure that the tissue lies within the treatment zone of the ice ball.

Reference data relating to a portion of a patient anatomy during patient motion can be acquired from a magnetic resonance imaging system (MRI) to develop a patient motion library. During a time of interest, tracking data is acquired that can be related to the reference data. Partial volumetric data is acquired during the time of interest and at approximately the same time as the acquisition of the tracking data. A volumetric image of patient anatomy that represents a particular motion state can be constructed from the acquired partial volumetric data and acquired tracking data.

Apparatus and methods are described including an endoluminal device configured to move along a portion of a lumen of a subject's body, an extraluminal imaging device, and at least one computer processor. While the endoluminal device moves along the portion of the lumen, a display displays an extraluminal image of the lumen in which a first indication of a location of the lumen is shown. The extraluminal imaging device acquires a sequence of extraluminal images of the endoluminal device moving along the portion of the lumen. The indication of the location of the lumen that is displayed is updated based upon the acquired sequence of extraluminal images, and the acquired sequence of images is displayed with the updated indication of the location of the lumen overlaid upon the images. Other applications are also described.

An interlocking system for a joystick in a catheter procedure system includes a joystick configured to generate a first voltage output signal based on a linear activation of the joystick and a second voltage output signal based on a rotational activation of the joystick. A joystick cover is disposed over the joystick and includes an upper portion having an electrode plating on an inner surface of the upper portion and a lower portion having an inner surface. A capacitive touch detection circuit is coupled to the electrode plating of the upper portion of the joystick cover and is mounted on the inner surface of the lower portion of the joystick cover. The capacitive touch detection circuit is configured to detect a proximal change in capacitance in the electrode plating of the upper portion of the joystick cover and to generate a touch output signal to indicate whether a change in capacitance has been detected. A signal enable circuit is coupled to the joystick and the capacitive touch detection circuit and is configured to generate a linear enable voltage output signal and a rotational enable voltage output signal based on whether a change in capacitance has been detected.
