Abstract:
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.

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.

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