A transapical removal device that can be deployed in a catheter procedure to capture for removal or alteration a mitral valve clip or heart tissue, such as the anterior leaflet of the mitral valve, and methods of use are disclosed. The removal device includes a delivery catheter configured to be deployed near a mitral valve using a guide catheter. The delivery catheter has a snare head at the distal end, which assumes a collapsed state during movement of the delivery catheter through the guide catheter and deployed state for capturing a mitral valve clip or anterior leaflet. The snare head has one or more ablation delivery catheters configured to ablate tissue surrounding the pre-positioned mitral valve clip or anterior leaflet. In some arrangements within the scope of the present disclosure, the removal device includes a deployment mechanism for deploying a new transcatheter valve into the mitral valve.

A robotic catheter procedure system includes a bedside system that has a percutaneous device, and an actuating mechanism configured to engage and to impart movement to the percutaneous device. The system also includes a workstation coupled to the bedside system. The workstation includes a user interface configured to receive a user input, ma display device configured to display an image, a control system operatively coupled to the user interface and the actuating mechanism. The control system is configured to generate a control signal and the actuating mechanism causes movement of the percutaneous device in response to the control signal. The control system is configured to slow movement of the percutaneous device via the actuating mechanism as an identified point on the percutaneous device approaches a structure requiring a change in direction of the percutaneous device.

An intracardiac echocardiography (ICE) catheter system that includes a control system disposed in a portable housing, the control system including a battery, and an ICE ultrasound circuit connected to the battery. The ICE ultrasound circuit is configured to be connected to be in communication with an ICE catheter and process data received from an ultrasonic array positioned of the ICE catheter. The Ice catheter system also includes a computing module having electronics and software loaded thereon capable of processing data, and a wireless module connected to the battery and the computing module, the wireless module configured to wirelessly communicate signals to a control counsel in one or more displays that are configured for use in an ICE catheter procedure. A catheter handle can be configured to include the control system obviating the need for a cable connecting the catheter handle in the control system.

A drive assembly for a catheter procedure includes a body configured to receive a percutaneous device where the body has a first end and a second end. A distal pinch is configured to releasably engage the percutaneous device. A proximal pinch is positioned on the first end of the body and is configured to releasably engage the percutaneous device. A linear drive mechanism is coupled to the body and configured to move the body to cause linear movement of the percutaneous device in a first direction while the proximal pinch is disengaged from the percutaneous device and the distal pinch is engaged with the percutaneous device.

A method of delivering an elongate medical device along a path to a target location using a catheter procedure system includes generating a cover for the path, tracking a location of a distal portion of the elongate medical device based on a set of real-time images, and determining a remaining path length based at least on the location of the distal portion of the elongate medical device. The remaining path length is a distance between the distal portion of the elongate medical device and the target location. The remaining path length decreases as the distal portion of the elongate medical device approaches the target location. The method further includes updating the remaining path length during movement of the elongate medical device; determining if the distal portion of the elongate medical device deviates from the path; adjusting the position of the elongate medical device if the distal portion of the elongate medical device deviates from the path; monitoring a distal portion of the elongate medical device in a real-time image set to identify prolapse; and advancing the elongate medical device to the target location at a velocity determined based at least on the remaining path length.

Provided is a catheter simulator capable of achieving an improved procedure in a catheter procedure for a tissue responsible for a heart structure. This catheter simulator comprises: a container 10 into which a liquid is filled; a heart model 100 which is installed in the container 10 in a state of being filled with the liquid, and is provided with an outer wall and a septum; and a pulsation pump 50 which is connected to the heart model 100 and generates a pulsatile flow in an internal space of the heart model. The heart model 100 is characterized in that a portion to be varied by the pulsatile flow is thinned compared with the other portions, and a space including the thinned portion is formed in a substantially closed state.
