Abstract: Various embodiments provide systems and methods for controlling a catheter with a catheter positioning device by using a remote controller and a guidewire control mechanism that may be used to draw a guidewire through a catheter coupled with the catheter positioning system. As the catheter is advanced over the guidewire by the catheter positioning device, the guidewire control mechanism may draw the guidewire away, such as collecting any slack on the guidewire. In further embodiments, the guidewire control mechanism may match the speed at which the guidewire is drawn to the speed at which the catheter advances and thereby maintain the position of the guidewire relative to the patient.

Abstract: Various embodiments enable an introducer for a catheter to be rotated around an axis and/or traversed backward and/or forward along the axis. In various embodiments, positioning of an introducer may be enabled by an introducer support configured to be rotated around an axis and/or extended or retracted along the axis. The introducer may be manually operated and/or operated by motors in a nose cone of a catheter positioning system. In various embodiments, a portion of the introducer support may be configured to flex. In other embodiment, positioning of an introducer may be enabled by an adjustable nose cone of a catheter positioning system.

Abstract: Systems, methods, and devices of the various embodiments provide a remote controller for a catheter positioning system configured to be operated with a single hand by a catheter positioning system operator. In an embodiment, the remote controller may include a thumb joystick control, first wheel control, and second wheel control. In an embodiment, the remote controller may include various visual indicators and/or haptic feedback mechanisms providing information to a catheter positioning system operator.

Abstract: Systems, methods, and devices of the various embodiments provide linearly stationary catheter drive assemblies enabled to move a catheter's sheath along a linear axis while holding the catheter handle stationary along that linear axis. In the various embodiments, the linearly stationary catheter drive assembly may be configured to move the catheter's sheath along the linear axis while holding the catheter handle stationary along the linear axis and rotating the catheter handle about the linear axis. In an embodiment, a linearly stationary catheter drive assembly may include a loop drive configured to move the catheter sheath along the linear axis. In an embodiment, a linearly stationary catheter drive assembly may include a pinch drive configured to move the catheter sheath along the linear axis.

Abstract: Various embodiments provide a catheter positioning device with components for controlling actuators of the catheter in multiple axes. A catheter may be attached to a sled member by a modular plate with one or more actuator interfaces that may couple with the actuators of a catheter handle. One or more motors or drives in the sled member may move the actuator interfaces of the modular plate to control one or more actuators on the catheter in different axes. In various embodiments the sled member may have a clam shell design in which two or more sides of the sled member close around the catheter handle. In further embodiments, the sled member may include adjustable faces that can fit different types of modular plates and thereby control actuators on different types of the catheter.

Abstract: A system for determining the disposition of a probe within the body of a patient includes a probe having probe field transducers and a plurality of reference field transducers. The reference field transducers are independently movable with respect to one another to desired, customizable positions close to the body of the patient. Calibration transducers determine the relative positions of the field transducers with respect to one another after they are located in their desired positions. Non-ionizing fields are transmitted and detected between the probe and reference field transducers. From the detected fields, the relative disposition of the probe with respect to the reference field transducers is determined.
