Abstract: A magnetically-guided catheter includes a tip positioning magnet in the distal electrode assembly configured to interact with externally applied magnetic fields for magnetically-guided movement. A magnetically-guided mapping catheter includes an electrically-conductive capsule in the form of a casing that includes a distal ablation surface and isolates the positioning magnet from bio-fluids to prevent corrosion. An open irrigation ablation catheter includes an isolated manifold that isolates the positioning magnet from contact with irrigation fluid to prevent corrosion.

Abstract: A magnetically-guided catheter includes a tip positioning magnet in the distal end portion thereof configured to interact with externally applied magnetic fields for magnetically-guided movement. The magnet may be geometrically asymmetric, for example, a C-shape in radial cross-section, so as to allow side-loading of an irrigation fluid lumen and other wire(s) or lines during fabrication. The outer shaft includes a plurality of segments, including a generally soft segment at the distal end thereof for magnetically-guided navigation. The fluid lumen, which extends through the outer shaft, and further extends completely through the magnet for coupling to the ablation electrode irrigation fluid inlet, is constructed so that its mechanical properties (i.e., flexibility) substantially matches that of the outer shaft. The combination of the outer shaft, inner fluid lumen and positioning magnet has interoperability with a broad range of ablation tip assemblies.

Abstract: An electrode coupling output system provides indication to the physician, via electrode guidance instrumentation, concerning the electrical coupling of an electrode, such as an ablative or mapping electrode, with a patient. The output can be provided to the physician via an output device incorporated into the handle set of the electrode catheter. For example, a visual, audio or mechanical output can be provided via the handle set. Additionally or alternatively, the output can be provided to the physician via a navigation system. The indication may be provided by changing the color or other display characteristics of the electrode on the navigation system display or by way of providing a waveform indicating the electrode coupling. In this manner, electrode coupling information is provided to a physician in a manner that minimizes physician distraction.

Abstract: An elongate medical device with independently-deflectable segments and a handle for manually deflecting those segments can include a shaft having a distal segment and proximal segment, at least one proximal segment deflection wire adapted to deflect the proximal segment, at least one distal segment deflection wire adapted to deflect the distal segment independent of the proximal segment, and a handle portion. The handle portion may comprise a first manual actuation mechanism coupled to the at least one distal segment deflection wire and a second manual actuation mechanism coupled to the at least one proximal segment deflection wire. Actuation of the first manual actuation mechanism may impart a tensile force on the distal segment deflection wire to cause the distal segment to deflect, and actuation of the second manual actuation mechanism may impart a tensile force on the proximal segment to cause the proximal segment to deflect.

Abstract: A robotic surgical system includes a track, a catheter holding device including a catheter receiving portion translatably associated with the track, a translation servo mechanism to control translation of the catheter holding device relative to the track, a catheter deflection control mechanism, a deflection servo mechanism to control the catheter deflection control mechanism, and a controller to control at least one of the servo mechanisms. The catheter receiving portion is adapted for quick installation and removal of a catheter. The catheter receiving portion may be rotatable, with a rotation servo mechanism to control the rotatable catheter receiving portion. The controller controls at least one of the deflection and rotation servo mechanisms to maintain a substantially constant catheter deflection as the catheter rotates. An introducer, which may be steerable, and an expandable, collapsible sterile tube may also be provided.

Abstract: A system and method for determining a position of a medical device within a body are provided. The system includes an electronic control unit that receives position signals from position sensors of a first type and a second type disposed on the device and applies a filter to each of the position signals to obtain filtered estimated positions for each sensor. The unit computes a spline connecting the position sensors of the first type responsive to the filtered estimated positions for the sensors and estimates a spline position for the sensor of the second type along the spline. The unit generates maps between the spline position and filtered and unfiltered estimated positions for the sensor of the second type and determines actual positions for the sensors of the first type responsive to the filtered estimated position for the sensors and a composite map of the two maps.

Abstract: Systems for detecting when catheter electrodes enter into and exit from an introducer are disclosed. In one form, a system detects a relative position of a catheter (comprising a marker band and an electrode) and an introducer (comprising a proximity sensor adapted to sense the marker band), while the catheter and introducer are in a human body. The system may comprise an electronic control unit to analyze signals from the catheter and/or the introducer, to determine whether the catheter electrode is within the introducer; and to disregard data collected from the electrode when that electrode is in the introducer. The sensor may he on the catheter and the sensed element may be on the introducer. The sensed element may comprise one or several marker bands. A marker band may be applied during the manufacture of a medical device or during its use and is any element capable of electromagnetic detection.
