Surgical system and related methods
A surgical system can include a surgical probe having a deflectable tip, and a plurality of guide arms that are movable so as to cause the tip to deflect. Thus, the surgical probe can be steered toward a target anatomical location. The surgical system can further include a control system that includes a free floating user interface, and a motion sensor that detects motion of the user interface. The control system is configured to cause the probe tip to deflect in response to the detected motion of the user interface.
Tissue ablation and monitoring thereof
An ablation catheter including an elongate shaft, an inflatable balloon positioned at a distal region of the elongate shaft, a first ablation electrode disposed outside of and carried by an outer surface of the inflatable balloon, a first ultrasound transducer disposed outside of the inflatable balloon, and a flexible circuit. The flexible circuit includes a first conductor and a second conductor and is disposed outside of and carried by the outer surface of the inflatable balloon. The first conductor is in electrical communication with the first ablation electrode, and the second conductor in electrical communication with the first ultrasound transducer.
REMOTE ROBOTIC ACTUATION OF A TRANSEOPAGEL ECHOCARDIOGRAPHY PROBE
A replica control tool (70) for remotely controlling a control handle (71) of an interventional tool (e.g., a probe, a catheter and a flexible scope) robotically controlled by a robotic actuator (50). The replica control tool (70) employs a replica control handle (71) substantially being a replica of a structural configuration of the control handle (71) of the interventional tool, and a control input device (72) (e.g., a joystick or a trackball) movable relative to the replica control handle (71). The replica control tool (70) further employs a robotic actuator controller (75) for remotely controlling the robotic actuator (50) in response to any movement of the control input device (72) relative to the replica control handle. The replica control tool (70) may further employ an electromechanical device (73) (e.g., an accelerometer) co-rotatable with the replica control handle (71) whereby the controller (75) remotely controls the robotic actuator (50) in response to a rotation of the electromechanical device (73).
VISUALIZATION DEVICES FOR USE DURING PERCUTANEOUS TISSUE DISSECTION AND ASSOCIATED SYSTEMS AND METHODS
A device and method for visualization of the intravascular creation of autologous valves, and particularly venous valve, is disclosed herein. One aspect of the present technology, for example, is directed toward a delivery catheter that can include a lumen configured to receive a dissection assembly and a trough having a plurality of transducers electrically coupled to a proximal portion of the delivery catheter. At least one of the transducers can be configured to emit a signal towards a portion of a blood vessel adjacent the trough, and at least one of the transducers can be configured to receive a reflection of the emitted signal.
INDUCTIVE DOUBLE FLAT COIL DISPLACEMENT SENSOR
A catheter adapted to measure a contact force includes a proximal segment, a distal segment, a spring segment extending from the proximal segment to the distal segment, and at least one inductive sensor. The at least one inductive sensor includes a first plate of high magnetic permeability material disposed on the proximal segment, a second plate of high magnetic permeability material disposed on the distal segment opposite the first plate, at least one first coil disposed adjacent to the first plate between the first plate and the second plate, and at least one second coil disposed adjacent to the second plate opposite the first coil between the first plate and the second plate. The second coil is electrically connected in series with the first coil. The first coil and the second coil are configured to output a signal indicative of displacement between the first coil and the second coil.
Flexible RF ablation needle
Devices, methods, and systems for the treatment of tissue using energy delivery. Specifically, certain embodiments may be used for the treatment of lung tissue, such as lung nodules, using RF ablation, via a catheter provided with a first electrode attached to a distal end of the catheter, wherein the first electrode is hollow, wherein the first electrode comprises a piercing tip configured to pierce through an airway wall and a second electrode received in a movable manner within the first electrode, wherein the second electrode is extendable from the first electrode to form a first extended configuration.
ASSESSMENT OF SUTURE OR STAPLE LINE INTEGRITY AND LOCALIZATION OF POTENTIAL TISSUE DEFECTS ALONG THE SUTURE OR STAPLE LINE
A method for assessing suture line integrity includes loading a navigation plan into a navigation system, the navigation plan including a planned pathway shown in a 3D model, inserting a probe into a patient's airways, the probe including a location sensor in operative communication with the navigation system, registering a sensed location of the probe with the planned pathway, and selecting a target in the navigation plan, the target including a proposed suture line. The method further includes presenting a view of the 3D model showing the planned pathway and indicating the sensed location of the probe, navigating the probe through the airways of the patient's lungs toward the target, and imaging the proposed suture line of the target, via the probe, to determine tissue integrity surrounding the proposed suture line.
Methods and apparatus for utilizing impeller-based rotationally-scanning catheters
An ablation catheter includes a tubular catheter body having a lumen, a tip portion, a liquid inlet, at least one liquid outlet, a liquid flow path defined between the liquid inlet and the liquid outlet, and an ablation element mounted on the tip portion of the catheter body. A rotationally-scanning ultrasound assembly is disposed within the lumen of the catheter body adjacent the tip portion. The ultrasound assembly includes an ultrasound transducer having an active face, an acoustic mirror acoustically coupled to the active face of the ultrasound transducer, and an impeller positioned in the liquid flow path and operably coupled to at least one of the ultrasound transducer and the acoustic mirror to impart rotational motion thereto when a liquid flows through the impeller.
Material removal device and method of use
A catheter having a tubular body and a rotatable shaft disposed within a lumen of the tubular body. A cutting element is coupled to the rotatable shaft, the cutting element having a cutting edge, the cutting element and rotatable shaft being longitudinally moveable within the tubular body between a stored position in which the cutting element is parallel a longitudinal axis of the tubular body and a cutting position in which the cutting element is deflected between the proximal and distal ends of the tubular body to extend beyond an outer diameter of the tubular body. The cutting element is configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The catheter includes a collection chamber positioned proximally of the cutting window.
ARRANGEMENT FOR MONITORING A POSITIONING OF A PROSTHETIC CARDIAC VALVE AND CORRESPONDING METHOD
A prosthetic cardiac valve implantation arrangement is described. The prosthetic cardiac valve implantation arrangement includes a prosthesis catheter with a prosthetic cardiac valve to be implanted; and an ICE catheter for introduction into area surrounding a cardiac valve to detect a relative position and/or relative direction of orientation of the cardiac valve with respect to the ICE catheter with the aid of an ultrasound image of the cardiac valve recorded by the ICE catheter. In addition, a navigation system is for determining an absolute position and an absolute direction of orientation of the ICE catheter; and a control facility is for controlling the insertion of the prosthetic cardiac valve into the annulus of the cardiac valve on the basis of the ultrasound image recordings of the ICE catheter and positional and/or orientation-direction information from the navigation system. Also described is a method for monitoring a catheter-based prosthetic cardiac valve implantation.
