Systems and methods for inter-arm registration include a computer-assisted system having a control unit coupled to a repositionable arm of a computer-assisted device. The control unit is configured to: receive, from an imaging device, successive images of an instrument mounted to the repositionable arm; determine an observed velocity of a feature of the instrument; determine an expected velocity of the feature of the instrument based on kinematics of the repositionable arm; transform the observed velocity and/or the expected velocity to a common coordinate system using a registration transform; determine an error between directions of the observed and expected velocities in the common coordinate system; and update the registration transform based on the determined error. In some embodiments, the instrument is a medical instrument and the imaging device is an endoscope. In some embodiments, the control unit is further configured to control the instrument using the registration transform.

A robotic catheter procedure system includes a bedside system and a workstation. The bedside system includes an actuating mechanism configured to engage and to impart movement to a percutaneous device. The workstation includes a user interface and a control system configured to be operatively coupled to the user interface, the bedside system, and a medical imaging system. The control system is responsive to a first input and to a second input, and the user interface receives the second input from a user. The control system is configured to generate a first control signal to the medical imaging system based on the first input, and the medical imaging system captures at least one image in response to the first control signal. The control system is configured to generate a second control signal to the actuating mechanism based on the second input, and the actuating mechanism causes movement of the percutaneous device in response to the second control signal. The first input is indicative of upcoming percutaneous device movement.

An ultrasound cardiac stimulation system includes: a system for measuring the heart electrical activity; a system for generating a beam of focussed ultrasound signals focussed on a targeted zone, the signals being calibrated to generate electrical stimulation in a zone of the heart, the beam generation being synchronised with a first selected time of the electrocardiogram, the generation of the beam corresponding to a pulse with a duration of less than 80 ms; a system for locating the targeted zone coupled with a system for positioning the system for generating the focussed beam to control the beam of focussed ultrasound signals in the targeted zone, the location system being synchronised with the system for generating the beam of focussed signals; a single monitoring system following in real time a temperature and tissue deformation in the targeted zone, the monitoring system taking measurements in synchronisation with the rhythm of the electrocardiogram.

A method and system for determining a target location for a medical device having complex geometry relative to an anatomical feature, and for navigating and positioning the medical device at the target location. The system may include a medical device including a treatment element having a centroid, one or more navigation electrodes, and a longitudinal axis and a navigation system in communication with the one or more navigation electrodes, the navigation system including a processing unit. The processing unit may be programmed to define a plane that approximates a surface of the anatomical feature, define a centroid of the anatomical feature, define a vector that is normal to the plane and extends away from the centroid of the anatomical feature, and determine a target location for the treatment element of the medical device based on the vector to assist the user in placing the device for treatment.

A tissue expansion system includes an expandable bladder for placement beneath the skin corresponding to a tissue to be expanded, a fluid source, a pump coupled to both the fluid source and the expandable bladder to deliver inflation medium thereto, a controller for the pump, a pressure sensor for monitoring pressure within the expandable bladder and informing the action of the controller, and a carrier for holding at least the fluid source, pump, and controller. The carrier is wearable as a bra or form-fitting vest and is shaped to mimic the appearance of natural breasts for the patient. The fluid source can have an outward facing surface that is relatively rigid to maintain a curved shape mimicking that of natural breast(s). The inward facing surface of the fluid source may be flexible to conform to the shape of the underlying skin and tissue as it is expanded.

Apparatus, systems, and methods are provided for localization of a needle within a patient's body using markers. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region and one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region. A processor processes the modulated reflected signals at one or more of the surface locations to determine marker locations along the needle and generate a three-dimensional model of the body region and needle.

An aspiration thrombectomy system is described with an aspiration catheter assembly having fittings interfaced with conduit and a pump. The aspiration catheter assembly can include a guide catheter and an aspiration catheter. The aspiration catheter can be positioned into an artery with a distal opening positioned proximal to a clot. The fittings can include a filter for removing thrombus from the aspiration flow. The fittings can include a flow meter for measuring flow to the pump. The fittings can include a pressure sensor for measuring pressure in the fittings. The aspiration catheter can be manipulated based on pressure and flow measurements. The fittings can include a docking manifold that can dock the connection suction of the suction extension to allow removal of the suction extension from hemostatic isolation and clearing of clots from the suction extension without further fittings such that the cleared suction extension can be efficiently reinserted for additional use.
