Benefits of technology

[0009]A magnetically-guided ablation catheter is introduced into the chamber to be used to deliver therapeutic energy. The an ablation catheter can be used in an ablation procedure to apply energy (e.g., radio frequency electrical) to a specific location within the heart is to necrotize (kill) tissue and block neural conductio

Problems solved by technology

Unfortunately, mapping of the heart chamber using prior art systems is a time-consuming process that increases the cost and risk of ablation procedures.
The mapping process is complicat

Embodiment Construction

[0023]FIG. 1 shows a distal end of a spiral mapping catheter 4 and a distal end of an ablation catheter 1. The mapping catheter 4 includes a plurality of electrodes including an electrode 4.1 disposed at or near the distal end of the catheter 4, an electrode 4.2 disposed at a position on the catheter 4 less distal than the electrode 4.1, etc. The ablation catheter 1 is introduced into a coronary chamber via a sheath (or introducer) 2. The sheath (or introducer) 2 includes a tube which is inserted through a vein or other pathway or orifice into the heart. Catheters, wires and / or fluids can be introduced into the heart chamber through this tube.

[0024]In one embodiment, the tip of the ablation catheter 1 contains a magnetically-doped core element and sensory electrodes. The magnetic indicator 3 displays the current direction of the magnetic field that is guiding the catheter tip. A spiral mapping catheter 4 is introduced into the chamber and manually guided by levers on its handle (e.g...

Abstract

A system and method is described for a catheter guidance system which allows an operator to use a mapping catheter to specify tissue target locations for the automatic guidance of a second therapeutic catheter. The operator places a mapping catheter at a desired location, and commands the catheter guidance system by either selecting a point on that catheter or one of the catheter electrode electrocardiograms. The operator may target the selected dynamic location, or tissue contact beyond that location on a specific side of the mapping catheter.

Description

BACKGROUND[0001]1. Field of the Invention[0002]The invention relates to the systems and methods for guiding, steering and advancing an invasive medical device in a patient.[0003]2. Description of the Related Art[0004]In cardiac electrophysiological procedures, mapping catheters are used to define the geometry of a coronary chamber and map its surface electrocardiogram. Mapping catheters contain an array of electrodes which are used for position location and sensing the surface electrical activity. For sensing electrical activity, these electrodes are either used individually or in differential pairs, depending upon the type of sensory hardware available. When the surface has been fully mapped, a mapping catheter is often used in conjunction with an ablation catheter to locate and deliver therapeutic treatment at specific locations. The mapping catheter is returned to the area of interest, and the electrogram at each electrode or electrode pair is observed on the data recorder to det...
